Using Ruby to get email attachment ID

I am trying to loop through a set of emails, and get their email attachment ID. I can't seem to get down to the ID, though.

I've gotten this far:

class AccessEmailController < ApplicationController

def access_email

    client = Signet::OAuth2::Client.new(access_token: session[:access_token])
    service = Google::Apis::GmailV1::GmailService.new
    service.authorization = client

    user_id = 'me'

    email_list = service.list_user_messages('me', q: "subject:(CCC Data)")
    
    message = 'No Emails Found' if email_list.messages.empty?
   
    email_list.messages.each do |message|
        message_id = message.id
        @subject = service.get_user_message(user_id, message_id).payload.parts

    end
end

end

And, if I display @subject in a view, I get:

[#<Google::Apis::GmailV1::MessagePart:0x00007f8630c397a0 @headers=[#<Google::Apis::GmailV1::MessagePartHeader:0x00007f8630c344a8 @name="Content-Type", @value="multipart/alternative; boundary=\"00000000000020396d05b7ceda38\"">], @mime_type="multipart/alternative", @body=#<Google::Apis::GmailV1::MessagePartBody:0x00007f8630c39250 @size=0>, @filename="", @part_id="0", @parts=[#<Google::Apis::GmailV1::MessagePart:0x00007f8630c30588 @headers=[#<Google::Apis::GmailV1::MessagePartHeader:0x00007f8630c2d2e8 @name="Content-Type", @value="text/plain; charset=\"UTF-8\"">], @mime_type="text/plain", @body=#<Google::Apis::GmailV1::MessagePartBody:0x00007f8630c2ed50 @size=91, @data="-- \r\nKim Floyd (Davis)\r\n\r\nWeb Developer, EvenVision\r\n707.845.3073\r\nk.davis@evenvision.com\r\n">, @filename="", @part_id="0.0">, #<Google::Apis::GmailV1::MessagePart:0x00007f8630c2be98 @headers=[#<Google::Apis::GmailV1::MessagePartHeader:0x00007f8630c2a840 @name="Content-Type", @value="text/html; charset=\"UTF-8\"">, #<Google::Apis::GmailV1::MessagePartHeader:0x00007f8630c29ff8 @name="Content-Transfer-Encoding", @value="quoted-printable">], @mime_type="text/html", @body=#<Google::Apis::GmailV1::MessagePartBody:0x00007f8630c2b858 @size=344, @data="<div dir=\"ltr\"><br clear=\"all\"><div><br></div>-- <br><div dir=\"ltr\" class=\"gmail_signature\" data-smartmail=\"gmail_signature\"><div dir=\"ltr\">Kim Floyd (Davis)<div><br><div>Web Developer, EvenVision</div><div>707.845.3073</div><div><a href=\"mailto:k.davis@evenvision.com\" target=\"_blank\">k.davis@evenvision.com</a></div></div></div></div></div>\r\n">, @filename="", @part_id="0.1">]>, #<Google::Apis::GmailV1::MessagePart:0x00007f8630c28f68 @headers=[#<Google::Apis::GmailV1::MessagePartHeader:0x00007f8630c27b90 @name="Content-Type", @value="image/png; name=\"image.png\"">, #<Google::Apis::GmailV1::MessagePartHeader:0x00007f8630c26fd8 @name="Content-Disposition", @value="attachment; filename=\"image.png\"">, #<Google::Apis::GmailV1::MessagePartHeader:0x00007f8630c266f0 @name="Content-Transfer-Encoding", @value="base64">, #<Google::Apis::GmailV1::MessagePartHeader:0x00007f8630c25d40 @name="X-Attachment-Id", @value="f_kjdr80n00">, #<Google::Apis::GmailV1::MessagePartHeader:0x00007f8630c25250 @name="Content-ID", @value="<f_kjdr80n00>">], @mime_type="image/png", @body=#<Google::Apis::GmailV1::MessagePartBody:0x00007f8630c28a90 @size=459005, @attachment_id="ANGjdJ9LKnYW-GChtR3_oaBWnwi0DjHG4I8ZeDuMskuJ6htxLGmwNaB-v3x0k_cP94ybJFg0HLPO0AkSLWb-zXvF25qaGyhA20R89kwPSC9j3ttVEsBhByEAxrPkJQVwKuf3H8EblPhNNfPA7iYEJ7zT56do8-_UbMbDuXo-fVU445mtPHSYHWOEX_4z8aUyNTU3MCzNY8EHz90mJRpJnseelK3whaZdcJ2E98XmxQ">, @filename="image.png", @part_id="1">]

Which, does contain the attachment I am looking for. How can I get down to that attachment, though, and get it's ID?

How can I make a Rails which can auto locate place and display as google map?

I am trying to make a simple program which can locate your place, for example when you enter your place my program will display your map as google map.

When I search by google, they said that I can use Gmaps4rails, but unfortunately that it seems obsolete and I can not use it anymore.

Could you please give me any idea? Or some link ?

Thank you very much.

JWT Auth giving error when attempting to login user

Im using JWT with a Rails backend/React frontend. Im attempting to have my user redirected when they log into their account to the /home page of the site. The error I am receiving is

TypeError: Cannot read property 'push' of undefined
Login.<anonymous>
src/components/Login.js:20
 17 |   if(res.user){
 18 |     localStorage.token = res.token

Ive did make a change, to the home component but since reverted back to what it was but still having issues....

my controllers...

Uploading .heic images in Rails 3.2 using paperclip gem

Users are unable to upload .heic images. Doesn't seem to be as simple as adding "images/heic" to content_type validations or just changing the file type to .jpg or .png. Is there a way to get this done using paperclip or should we use an API to convert the .heic image to .jpg or .png before attaching and uploading?

        format.json { render :show, status: :ok, location: @review }
      else
        format.html { render :edit }
        format.json { render json: @review.errors, status: :unprocessable_entity }

  def correct_user
    @review = current_user.reviews.find_by(id: params[:id])
    redirect_to reviews_path, notice:" Not Authorized to Edit This Review" if @review.nil?
    end

Still pretty new to Rails, any help would be great!

Correct Installation of Google Analytics on Ruby on Rails

I have a friend who has a developer working on this site: https://www.cannasaver.com/

When I access different pages on the site the UA code seems to duplicate over and over again according to the Google Tag Manager extension.

The developer is saying this is normal implementation and there there is nothing wrong. However on the other sites they own such as this: http://cannapages.com/ -- this does not seem to be the case.

I am wondering if the Google Analytics code is correctly implemented on https://www.cannasaver.com/ -- Any help you have as to if it is correctly added or what to do to fix it would be great appreciated!

Could not run the `identify` command. Please install ImageMagick

I am using Paperclip and getting this error on the deployed site, not on my local server. And that's why it is becoming more difficult for me to get out of this.

A Paperclip::Errors::CommandNotFoundError occurred in images#update:
enter code hereCould not run the `identify` command. Please install ImageMagick.

I have tried these solutions but was not able to fix this (For ubuntu):

Ran apt-get install imagemagick
I don't use brew. So, won't be able to use brew install imagemagick
Added and deployed these lines to paperclip_options.yml

:image_magick_path: '/opt/ImageMagick/bin' :command_path: '/opt/ImageMagick/bin'

Can anyone suggest how to resolve this error?

View action should show same response which I get on form submission

I have registration form , once I have submit that form , I was getting some response. I want to show same response on view action. Currently, I have registration page which have two tabs, one is for registration form and other is for post register activity form.where second tab is disabled till I have submitted the registration form. I am able to submit a form and getting response as well, now I want show same response on view action, How should I achieve that in rails web project ? How should my routes work in that case ?

Match request URL params with rails routes via recognize_path

I want to check if any incoming request actually exists in routes.rb as an entry via recognize_path like this

def path_exists?(path)
  Rails.application.routes.recognize_path(path)
  true
  rescue
   false
end

This works for most URLs but if the URL has a parameter, then it fails to recognize it.

Example:

In routes.rb, say I have an entry like this

put "foo/bar/:param" => "foo#bar"

and the incoming request URL is of the form /foo/bar/5

Then the function recognize_path doesn't recognize the URL as the value of the parameter is 5 but it is matched with :param

How do I match requests that have parameters to their entries in routes.rb using recognize_path or any other similar function?

Reason

I'm filtering out malicious attempts to hit the server using random URLs like /dump.sql.tar.gz, /conf.xz, etc using the gem rack::attack and throttling requests whose URLs are not a part of routes.rb. Hence the above problem.

Ruby on Rails - Criteria - Mongoid - where condition with 2 by 2 columns

I'm working with RoR + MongoDB (Mongoid) and I need to apply a filter using or condition by 2 columns.

I saw some recommendations like this one but didn't work.

query = query.where(name: /#{attributes[:name]}/i).or(query.where(email: /#{attributes[:email]}/i))

If I use this one, looks like the or will be applied for all conditions:

query = query.where(name: /#{attributes[:name]}/i).or(email: /#{attributes[:email]}/i)

Anyone has any suggestion?

Get this "RSA/ECB/OAEPWithSHA-256AndMGF1Padding" combination for ruby

I have this java code for encryption and decryption, which I want to change/convert to Ruby code. I looked up in OpenSSL gem but dint find the "RSA/ECB/OAEPWithSHA-256AndMGF1Padding" combination available for ruby. How do I implement it?

public class EncryptDecryptService {
    
    public String encryptRequestObject(RequestObject requestObject) throws UnsupportedEncodingException, FileNotFoundException, CertificateException, InvalidKeyException, NoSuchAlgorithmException, NoSuchPaddingException, IllegalBlockSizeException, BadPaddingException {
        PublicKey publicKey = getPublicKey(requestObject.getKeyFilename());
        byte[] message = requestObject.getString().getBytes("UTF-8");
        byte[] secret = encrypt(publicKey, message);
        return Base64.encodeBase64String(secret);
    }
    
    public String decryptRequestObject(RequestObject requestObject) throws UnrecoverableKeyException, KeyStoreException, NoSuchAlgorithmException, CertificateException, IOException, InvalidKeyException, NoSuchPaddingException, IllegalBlockSizeException, BadPaddingException {
        PrivateKey privateKey = getPrivateKey(requestObject.getKeyFilename(), requestObject.getKeyPassword());
        byte[] cipherText = Base64.decodeBase64(requestObject.getString());
        byte[] decrypted = decrypt(privateKey, cipherText);
        return new String(decrypted, "UTF-8");
    }
    
    private PublicKey getPublicKey(String filename) throws FileNotFoundException, CertificateException {
        FileInputStream fin = new FileInputStream(filename);
        CertificateFactory factory = CertificateFactory.getInstance("X.509");
        X509Certificate certificate = (X509Certificate) factory.generateCertificate(fin);
        PublicKey publicKey = certificate.getPublicKey();
        return publicKey;
    }
    
    private PrivateKey getPrivateKey(String filename, String password) throws KeyStoreException, NoSuchAlgorithmException, CertificateException, IOException, UnrecoverableKeyException {
        FileInputStream fin = new FileInputStream(filename);
        KeyStore ks = KeyStore.getInstance("pkcs12");
        ks.load(fin, password.toCharArray());
        String str = ks.aliases().nextElement();
        PrivateKey privateKey = (PrivateKey) ks.getKey(str, password.toCharArray());
        return privateKey;
    }
    
    private byte[] encrypt(PublicKey key, byte[] plainText) throws NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException, IllegalBlockSizeException, BadPaddingException {
        Cipher cipher = Cipher.getInstance("RSA/ECB/OAEPWithSHA-256AndMGF1Padding");
        cipher.init(Cipher.ENCRYPT_MODE, key);
        return cipher.doFinal(plainText);
    }
    
    private byte[] decrypt(PrivateKey key, byte[] cipherText) throws NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException, IllegalBlockSizeException, BadPaddingException {
        Cipher cipher = Cipher.getInstance("RSA/ECB/OAEPWithSHA-256AndMGF1Padding");
        cipher.init(Cipher.DECRYPT_MODE, key);
        return cipher.doFinal(cipherText);
    }
}

Find records have count of association > n

class PurchaseOrder < ApplicationRecord
  has_many :purchase_order_materials 
end 
class PurchaseOrderMaterial < ApplicationRecord
  belongs_to :purchase_order
  belongs_to :material
end

I have this query:

PurchaseOrderMaterial
  .includes(:purchase_order, :material)
  .where("purchase_orders.provider_id IS NULL AND purchase_orders.status = ? 
          AND (purchase_orders.is_waiting != ? 
               OR purchase_orders.is_waiting IS NULL)", 
         PurchaseOrder.possibleStatus.first, true)

All i want it's filter results to purchase_order.purchase_order_materials.count > 1. Some way to achieve it?

Weird time.beginning_of_month rails 3 behavior

I am working on this query:

Student.where(created_at: time.beginning_of_month..time). Let's say the time here is: `15/10/2020 00:00:00`

I thought this is supposed to return the created students from 1/10/2020 00:00:00 to 15/10/2020 00:00:00 because time.beginning_of_month returns 1/10/2020 00:00:00

However, it returns me the created students from 30/09/2020 22:00:00 to 15/10/2020 00:00:00

I have checked with other months and I get the same results. Somehow, it always returns me the records starting from the last day of the previous month, not the first day of the current month

I am using Rails 3.2.2 and Ruby 2.1.5

Gems are not found inside Docker container After sourcing RVM path

scenario1

So the problem I am facing like after building the docker images. If I am going inside the docker container and doing GEM_PATH=$GEM_HOME gem list it is not showing all the gems installed at the time of building the image. it is showing only a few gems.

scenario2

If I am not sourcing the RVM path inside the Dockerfile. Then If I am going inside the docker container and doing GEM_PATH=$GEM_HOME gem list then it is showing all the gems.

Can anyone please explain to me why this is happening and how I should install and source RVM? So I can see all the gems inside the container. Basically, I want the scenario1 should work. Thanks

Below is my Dockerfile

Create multiple objects while seeding in Ruby on Rails

I have the following seed file that creates many animals which are then added to the animal_store object

animal_store_seeder:

animal1 = create(:animal)
animal2 = create(:animal)
animal3 = create(:animal)

create(
  :animal_store,
  json: {
    "animals": {
      animal1.id=> {
       }, 
      animal2.id =>{
    }
   ... 
  }
}

So far this works. However, I want to create a store with at least 20 animals. I don't think creating each variable is the correct way to go. Is there a better way to instantiate more animals and adding them to the animal_store without having to create them one at a time?

rspec parallel tests without database

I'm using RSpec as an API test harness that does not have a database during testing, and would like to parallelize the runs. I've tried https://github.com/grosser/parallel_tests but the rake task fails when there is no database with Don't know how to build task "'parallel:spec'".

I then moved to the deprecated https://github.com/yuku/parallel-rspec which worked, but it's not passing the arguments I've been using to filter tests correctly.

For example, if I had 10 tests, 2 of which had metadata feature=search would historically run:

bundle exec rspec --tag feature:search

And only those 2 tests would be run.

Now running

`` bundle exec parallel-rspec spec --tag feature:search

still runs all 10 tests.

How can I split up my specs into parallel runs while still preserving the ability to filter by metadata?

No such file or directory - java rake aborted

I'm having a rails project running properly on my local machine but when I deploy it on heroku I get the error below. I seem not to understand what I'm not doing well. Initially, the project was using gem bootstrap-will_paginate, I removed it and switched to gem bootstrap. Right now as I have mentioned above, locally, the project is running as expected but when I try to deploy to heroku, I run into the error below. Any assistance will be highly appreciated. Thanks

I will also highlight the line whatever line shows the error it is just one line. I do not I think it coding thing is right. but, I guess I am missing some inside the code or probably on routes.rb

Is it possible to use onchange on base select option

Is there a way to use a submit onchange on this select option. I know I can do it on the <% f.select%> one with :onchange => 'this.form.submit()'), but I can't find any documentation on how to do it on this select statement.

<%= form_for(@profile_option, remote: true) do |form| %>

    <div class="form-group" id="profile_options_budgetid" >
      <div class="h7 text">Select Budget to Show</div>
         <select class="custom-select" name="profile_options[budget_id]" id="profile_options_budgetid">
           <option disabled value="" selected hidden>Please Select</option>
           <% Budget.where(user_id:current_user).each do |budget| %>
           <option value=<%= budget.id %>> Budget: <%= budget.month %> <%= budget.year %>
            </option>
                                            
             <% end %>

Having trouble using unless current_page? to hide a button

I'm trying to hide this button from all the show pages of the Rooms model. I have an array of the rooms id stored in @extra but whenever I try to use current_page?(room_path(@extra)) it doesn't work, but when I specify the id, for example, current_page?(room_path(6)) it works and hides the button. What am I doing wrong?

<% unless current_page?(controller: 'rooms') || current_page?(room_path(@extra))%>

   <button onclick="myFunction()" class="button btn btn-light bg-white rounded-pill shadow-sm px-4 mb-4" 
   style="vertical-align:middle">
   <span>
      <small class="text-uppercase font-weight-bold"> Nav-bar Toggle</small>
   </span>
</button>

      <% end %>

How do I hide button text with CSS?

I'm trying to hide the text Following when a user hovers over a button. I don't really have too much experience with CSS and am having difficulties doing this.

This is my button

<span>
   <%= link_to  'Following', follow_url(found), method: :delete, 
                class: "btn unfollow-button", id: 'unfollow-button', 
                data: { confirm: 'Are you sure?' } 
    %>
</span>

Below is the application.scss

.unfollow-button {
  width: 100px; /* set a width so it doesnt change upon hover */
  content: 'Following';
  border-color: #bd2b2b;
  background-color: #140d6d;
  color: white;
  margin-left: 20px;
  &:visited, &:focus, &:hover {
    content: 'Following';
    border-color: #FF0000;
    background-color: #FF0000;
    color: white;
  }

  
}
.unfollow-button:hover span {
  display:none
}
.unfollow-button:hover:before {
  content:" Unfollow ";
}

Right now the button is appending the new content Unfollow to the front of the button, but not removing the old content

So the button goes from Following to Unfollow Following instead of the desired result of Following to UnFollow

Any help would be greatly appreciated. Thanks!

Can I replace (Date.current - created_at.to_date).to_i <= number_of_days with number_of_days.days.ago.to_date? Is it a good idea?

In my models/book.rb I have this

  def created_since?(number_of_days)
    (Date.current - created_at.to_date).to_i <= number_of_days
  end

That is used in view files like

<% if @book.created_since?(30) %>

Can I optimize it editing with something like this?

  def created_since?(number_of_days)
    number_of_days.days.ago.to_date
  end

Is it a good idea? will it work the same?

Need a block of ruby code explained - or at least what I need to do to look it up

I'm a programmer, but I don't know ruby and/or ruby on rails at all. All I need to do is skip this validation check - have it return true - or return whatever value it returns if the hash is unique. I can't find explanations for the use of : nor :on Can anyone either explain to me what is happening here, or tell me how I can look up the pertinent symbols/terms?

class Stl < ApplicationRecord
  before_validation :compute_hash
  validates_uniqueness_of :md5hash, :on => :create

  mount_uploader :file, StlUploader
  belongs_to :product


  def compute_hash
    self.md5hash = Digest::MD5.hexdigest(self.file.read)
  end

How can I scrape a Website with onClick event listener using Nokogiri

I am trying to scrape a website using Nokogiri and download documents thats are posted on the website. I can scrape other websites like this one: Matatiela Website and get the documents from it. But when I try to scrape this website: Mbhashe Website I can't get the documents because I have to first triger the onclick event in order to get to the document.

The problem now, I don't know how to triger the onclick event in order to get to the document. I have tried this code that I worked on with my friend but it didn't work:

if url.include?('http://www.alfredduma.gov.za/bids-tender-notices/')
   file = anchor['onclick'].to_s.gsub("location.href=","").gsub(";return false;","").gsub("'","")
   f = mech.get(file)
   fileNmae = f.header['content-disposition']
   fileNmae = fileNmae.match('"(.*?)"').andand[1].to_s
   fileNmae = municipalityName+ " -" +fileNmae.gsub("_"," ")
   downld(municipalityName,file,filepath,fileNmae,provinceName)
end

This code didn't work. But bellow is the code that is similar to the one i used to scrape Matatiela website but it's not working on the website of Mbhashe. Can you please help me because it does not return anything.

["https://www.mbhashemun.gov.za/procurement/tenders/","div.tb > div.tbrow > a","http://www.mbhashemun.gov.za","Mbhashe municipality","Eastern Cape"]

My Myfuction gets the css from this array.

                            parenturl = anchor['href']

The code supposed to go throught the website and download the documents and save them on the public/uploads folder on the app.

Rails self reference one model with has_many

We want to achieve the following:

Be able to compare 'Projects' with other (multiple) Projects.
Save the comparison reference in the database.

In the past we did this by storing an array in the database like below:

t.string "comparisons", default: [], array: true

Now we are thinking about using another table - unless there is a better way?

Ideally something like this:

We already have this table:

|  projects |
|-----------|
| id | name |
| 1  | abc  |
| 2  | def  |
| 3  | ggg  |
| 4  | fff  |

We want to create another table similar to this:

|       project_comparisons     |
|-------------------------------|
| id | project_id | compared_id |
| 1  |     1      |      2      |
| 2  |     1      |      4      |
| 3  |     2      |      3      |
| 4  |     2      |      4      |

Where in the end we could do something like this:

Project.find(1).project_comparisons.each do |x|
  x.name
end

# Output:
'def'
'fff'

But we are getting lost in the relationship setup.

This is what we have so far:

rails g model ProjectComparison project:references compared:references

# Migration file (edited)
create_table :project_comparisons do |t|
  t.references :project, foreign_key: true
  t.references :compared
end


class Project
  has_many :project_comparisons
  has_many :projects, through: :project_comparisons
  # ... Here I think we need something in the line above?
end


class ProjectComparison
  belongs_to :project
end

This now has the the incorrect output. If we now iterate the example:

Project.find(1).project_comparisons.each do |x|
  x.name
end

# Output:
# aaa
# aaa

It should have been 'def' and 'fff'

Can I somehow specify that we want the 'compared_id' to get the correct Project, or are we on the wrong path here?

RSpec test module location

I am new to RSpec and I saw that in the sample the class tested is located in the lib folder. when 'require' class, it can directly import?(that is how I took it) the class from that folder. I tried require app/controllers/the_file_with_the_class_I_want_to_test and it says that it was not found. Should I copy and paste the file into the lib path?

trying to solve /usr/local/opt/openssl/lib/libssl.1.0.0.dylib (LoadError) led to bad interpreter: /usr/local/opt/python/bin/python2.7

After a brew upgrade, I couldn’t run any of my Ruby on Rails apps anymore. I got this error message:

: dlopen(/Users/ll/.rbenv/versions/2.6.2/lib/ruby/2.6.0/x86_64-darwin18/openssl.bundle, 9): Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib (LoadError) Referenced from: /Users/ll/.rbenv/versions/2.6.2/lib/ruby/2.6.0/x86_64-darwin18/openssl.bundle Reason: image not found - /Users/ll/.rbenv/versions/2.6.2/lib/ruby/2.6.0/x86_64-darwin18/openssl.bundle
So I tried

brew switch openssl 1.0.2t

solution sugests here https://stackoverflow.com/a/59184347/11410556 But couldn't find openssl 1.0.2t, my version was openssl@1.1 1.1.1h

Then I tried

brew uninstall --ignore-dependencies openssl brew tap-new $USER/old-openssl brew extract --version=1.0.2t openssl $USER/old-openssl brew install openssl@1.0.2t ln -s /usr/local/Cellar/openssl@1.0.2t/1.0.2t /usr/local/opt/openssl

suggest here: https://stackoverflow.com/a/64479513/11410556. But when I ran

brew switch openssl 1.0.2t

I got this Error:

openssl does not have a version “1.0.2t” in the Cellar.
openssl’s installed versions

So I went for this solution

brew unlink openssl@1.1 brew link openssl@1.0.2t

And then get:

Warning: Refusing to link macOS provided/shadowed software: openssl@1.0.2t
If you need to have openssl@1.0.2t first in your PATH run:
 echo ‘export PATH=“/usr/local/opt/openssl@1.0.2t/bin:$PATH”’ >> ~/.zshrc
For compilers to find openssl@1.0.2t you may need to set:
 export LDFLAGS=“-L/usr/local/opt/openssl@1.0.2t/lib”
 export CPPFLAGS=“-I/usr/local/opt/openssl@1.0.2t/include”
For pkg-config to find openssl@1.0.2t you may need to set:
 export PKG_CONFIG_PATH=“/usr/local/opt/openssl@1.0.2t/lib/pkgconfig”

I ran the first choice :

echo 'export PATH="/usr/local/opt/openssl@1.0.2t/bin:$PATH"' >> ~/.zshrc

restart my server and now I have

omz_urlencode:2: /usr/local/bin/pygmentize: bad interpreter: /usr/local/opt/python/bin/python2.7: no such file or directory (edited)

Whatever I do.

I'm not used to try things I don't understand and I think I went too far. I would be very grateful for any help to get out of this mess.

How to stop select statement from overwriting the other if they save to the same column

so I am trying to save one of these select statements depending on another select. I have both of these select statements hidden and if the previous select option is 1 goals is shown. If 2 is selected the budget is shown. But the problem is when I try to set the next value. The last select value overwrites the other. So if I select goals and try to save that value the budget select will overwrite it. What is the best way to stop this from happening?

<div class="form-group" id="goal_attachid" style="display: none;">
<%= form.label :"Select Goal to Attach" %>
   <select name="post[attachid]" id="goal_attachid">
    <option disabled value="" selected hidden>Please Select</option>
    <% Goal.where(user_id:current_user).each do |goal| %>
       <option value=<%= goal.id %>> Goal: <%= goal.title %></option>
    <% end %>
   </select>
  </div>

    <div class="form-group" id="budget_attachid" style="display: none;">
       <%= form.label :"Select Budget to Attach" %>
       <select name="post[attachid]" id="budget_attachid">
        <option disabled value="" selected hidden>Please Select</option>
        <% Budget.where(user_id:current_user).each do |budget| %>
           <option value=<%= budget.id %>> Budget: <%= budget.month %> <%= budget.year %>
        </option>
       <% end %>
  </select>
</div>

How to add a default value to sort: in query_type.rb

Existing code in query_type.rb:

def flags(program_id:, filter: {}, sort: {})
      program = Program.find(program_id)
      context[:auth].set_current_parent_program_id(program.id)
      flags = Report.joins(:participant).where(registrants: { program_id: program.id })
      Types::Programs::FlagsFilter.get_filtered(flags: flags, filter: filter, sort: sort)
 end

I am new to Ruby and the flags are coming in reverse order (ascending) and I want to set the default value to descending. I tried setting it like this:

def flags(program_id:, filter: {}, sort: { column: 'CREATED_AT', direction: 'DESCENDING' })
      program = Program.find(program_id)
      context[:auth].set_current_parent_program_id(program.id)
      flags = Report.joins(:participant).where(registrants: { program_id: program.id })
      Types::Programs::FlagsFilter.get_filtered(flags: flags, filter: filter, sort: sort)
 end

but I'm getting an error and my flags table is no longer rendering. Any suggestions?

Uppercase column names from MYSQL

Have an external MYSQL DB and I am connecting it to the ruby app. All the columns are changes to uppercase and when I try to query something it works but ruby gives an undefined method error when i try to call some field from the object like:

user = User.first works but when i do user.firstname it says undefined method firstname because the user object I get has firstname column as FIRSTNAME. How can I make it a case-incentive query so either i do user.firstname or user.FIRSTNAME it works?

i tried adding ActiveRecord::ConnectionAdapters::SQLServerAdapter.lowercase_schema_reflection = true into my cofig/initializers/activereport_sqlserver_adapter.rb but still no change.

Ng-repeat in angularjs with rails association

I am the beginner in angular js. I'm working on the project in which I have to use ng-repeat. In the backend, I have many to many self relationships(RoR). For example, I am using model A in rails for many to many self relations. Now my question is How should I use ng-repeat to show through table along with the model itself. I have used a single model using ng-repeat=" item in items" but this approach not good in this scenario. Please guide me in this regard thankyou.

(Relation Explanation) Suppose Model A has self-relation (many to many) with itself. I need model A to show some value through Model.something along with the attribute of model A through ng-repeat. We can easily use ng-repeat for i in Model A but i need rails associated object as well.

Conditional statement in Ruby on Rails

I'm working on Jira integration in my project. I wanted to add a condition to check if project_id is generated from the valid user account (same user account). If it is generated from valid user account then show the message Jira integration is successfulotherwise Jira integration is not successful.

This is the code that I'm using.

Jira.prototype.setJiraProject = function(projects) {
    var projectField = $("#project_id"),
      projectID = $("#project_id").val();
    projectField.find('option[data-type=jira-int]').remove();
    projects.map(function(el){
      if (projectID != el[0])
        projectField.append($('<option>', { 'data-type': 'jira-int', value: el[0], text: el[1]}));
    });
    projectField.attr('disabled', false).focus();
    showError('Jira integration is successful.', 'success');
  };

Is there anyway possible to achieve it?

Less/More option disappears on closing one notification (Ruby on Rails)

I'm writing a ROR code in which a notification at top will appear if transaction fails with Less/More option. But problem occurs when user closes one notification then Less/More option disappears for the other.

This is the code that I'm using

$(document).ready(function() {
    if ( $(window).width() < 1025 ) {
    var showChar = 20;
    var ellipsestext = "...";
    var moretext = "More";
    var lesstext = "Less";
    
    $('.confirm-account').each(function() {
        var content = $(this).html();
 
        if(content.length > showChar) {
 
            var c = content.substr(0, showChar);
            var h = content.substr(showChar, content.length - showChar);
 
            var html = c + '<span class="moreellipses">' + ellipsestext+ '&nbsp;</span><span class="morecontent"><span>' + h + '</span>&nbsp;&nbsp;<a href="" class="morelink">' + moretext + '</a></span>';
 
            $(this).html(html);
        }
    });
 
    $(".morelink").click(function(){
      $('.system-message').empty();
        if($(this).hasClass("less")) {
            $(this).removeClass("less");
            $(this).html(moretext);
        } else {
            $(this).addClass("less");
            $(this).html(lesstext);
        }
        $(this).parent().prev().toggle();
        $(this).prev().toggle();
        return false;
    });
  }

Is there any way possible in which the Less/More option remains there even after closing one notification?

How do I print out model data without printing the array?

I know that this is basic, but I cannot figure it out for whatever reason.

I'm trying to return some model data and the majority of the time I return it with pluck, but pluck is returning an array. How do I return the value without the array?

<dd><%= Goal.where(id:post.attachid).pluck(:title) %></dd>

This is the code that I have and it is returning, for example, ["Computer"]

How do I just make it return Computer

Sidekiq memory leak issue

I am using sidekiq gem to move my heavy reporting jobs to background. The problem is that sidekiq does not release memory even after a job is completed and it is causing an ever increasing memory bloat, resulting in sidekiq restart after every 4-5 jobs. I have tried ActiveRecord::Base.uncached and even tried this in my application.rb - config.middleware.delete "ActiveRecord::QueryCache" but still no use. Even GC.start is not working. How do I clear memory after every job?

Is there a way to use a where statement with multiple tables?

I have three tables

Table name: follows
#
#  id         :bigint           not null, primary key
#  following  :bigint
#  requestor  :bigint
#  created_at :datetime         not null
#  updated_at :datetime         not null
#  user_id    :bigint
#
# Indexes
#
#  index_follows_on_user_id  (user_id)
    belongs_to(
        :user,
        class_name: 'User',
        foreign_key: 'user_id',
        inverse_of: :follows
    )

User
has_many(
    :follows,
    class_name: 'Follow',
    foreign_key: 'user_id',
    inverse_of: :user
  )

Post
belongs_to(
        :user,
        class_name: 'User',
        foreign_key: 'user_id',
        inverse_of: :posts
    )

The requestor column takes a user.id.

I would only like to show the Posts where the requestor attribute == current_user.id. Am I only able to do this with a join or is there a way to do this with a where statement?

How do I use image_tag in

I'm unsure of how to replace the src= in the code below because previous attempts to replace it ended in failure.

<img class="rounded-circle" width="45" src="https://picsum.photos/50/50" alt="">

Previously I use to used <%= image_tag(@user.avatar, style: 'width:50%') %> to show images, but I prefer the styling of the <img class> more. If anybody can help we out with this on point me into the direction of some documention on this I would greatly appreciate it

AWS SecretsManager password rotation does not work in Rails

We are using AWS SecretsManager (SM) to store a rotating database password for our rails app. However, when SM rotates the password, we get "FATAL: password authentication failed for user".

The password is read in database.yml

password: '<%= AwsSecretService.new.get_db_pwd(ENV['DATABASE_USERNAME']) if Rails.env.production?   %>'

The problem appears to be that ActiveRecord is caching the database credentials from database.yml upon initialization and does not reparse database.yml.

My thought is to somehow trap the authentication failed error and reinitialize ActiveRecord. With the following command:

ActiveRecord::Base.establish_connection(::Rails.application.config.database_configuration[::Rails.env])

I'm not sure how to trap the error. Would I need to put an error handler in application_record.rb since all activerecord models inherit from it?

Or would it be better to use an Observer of some sort?

Ideas?

How to destroy model with values

I'm kind of new to rails. I have a model called follows that has to values (requestor and following). I am having trouble creating a button that destroys a select model with two values



<dt>User ID:</dt>
<dd><%= @user.id %></dd>

<dt>User email:</dt>
<dd><%= @user.email %></dd>

<% if Follow.where(:requestor => current_user.id, :following =>@user.id).present? %>    
    <%= button_to 'Unfollow', follow_url, method: :delete, class: "text-danger", data: { confirm: 'Are you sure?' } %>
<% else %>
    <%= button_to "Follow", {:controller => 'follows', :action => 'create', :requestor => current_user.id, :following => @user.id}, {:method => :post} %>
<% end %>

The Follow button below in the else statement works, but I cannot figure out how to get the destroy button to work. I'm executing these buttons on the User show page instead of on the follow index.

def destroy
    @follow.destroy
    respond_to do |format|
      format.html { redirect_to follows_url, notice: 'Follow was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_follow
      @follow = Follow.find(params[:id])
    end

    # Only allow a list of trusted parameters through.
    def follow_params
      params.permit(:requestor, :following)
    end
    def require_permission
      if Follow.find(params[:id]).user != current_user
        redirect_to goals_url, flash: { error: "You do not have permission to do that."}
      end
    end
end

I keep getting couldn't find Follow with 'id' error. It deletes sometimes, but the majority of the time I get this error.
