I am learning a rails on YouTube and here I am having issues with table style. The video is old and rails are update already. However, I am following exactly what he is doing in the video, but I ended up with this weird looking table of friends list.
I want to put all friends info next to each other up-and-down like the video.

In my uploader, if I am overriding the filename method present in Store.rb library of carrierwave, then upload functionality is not working. It is showing code executed properly but file was not uploaded on GCS bucket.
Below is the Carrierwave lib:
##
# Override this in your Uploader to change the filename.
#
# Be careful using record ids as filenames. If the filename is stored in the database
# the record id will be nil when the filename is set. Don't use record ids unless you
# understand this limitation.
#
# Do not use the version_name in the filename, as it will prevent versions from being
# loaded correctly.
#
# === Returns
#
# [String] a filename
#
def filename
@filename
end
This is what I implemented after overriding:
def filename
case model.type
when :video
"video_file"
when :mp3
"mp3_file"
end
end
Any help would be appreciated here. I wanted to change the filename if file is video or audio while uploading.

I tried to edit and update columns using Faraday Call on my rails app, I am successfully updating the columns by adding new value.
But I want during update, initially in edit_form, it must show my old values where i can edit it, and then update.
This is my Connection Request
def connection
Faraday.new(url: ENV['URL'],
params: { clientId: ENV['CLIENT_ID'] },
headers: { 'Authorization' => oauth_token_generation })
end
This is my edit_request to call end point for connection and update
def edit_request(type,id, params)
response = connection.patch("#{type}/#{id}", params)
JSON.parse(response.body)
rescue JSON::ParserError
Rails.logger.error 'Invalid Json Data'
nil
rescue Faraday::Error => e
Rails.logger.error "Connection Failed #{e}"
nil
end
This is my calling method:
def self.get_entities(id,params)
response = Api::Connection.edit_request('entities',id, params)
end
My Controller:
def edit
@schemas = Api::ApiCall::Schema.get_entities(params[:id],params)
end
def update
end
This is my Edit Form where I want to initailly retrive all data then edit and update:
<%= form_for(:schemas, url:schemas_path) do |f| %>
<%= f.text_field :schemaId, placeholder:"Schema Id"%>
<%= f.text_area :name, placeholder: "Schema Name"%>

I have an 2 array with some String values. I wanted to check if one array's all value are part of another arrays. Is there any defined method available to check it or how to implement in optimised way.
Ex:
arr1['abc', 'def']
arr2['abc', 'def', 'ghi', 'jkl']
if values of array 1 is present in array 2 then only control should move ahead in code else it should return.

I want to upload a file from remote url to GCS bucket via ruby code. Any suggestion here would be really appreciated.
In my workflow yaml file, I have a step that sends slack notifications if the deployment step fails i.e if it exits with a non-zero exit status. The build succeeds in Heroku but the release phase fails and the app fails to deploy to the server. We don't get notified of this release failure. How can I modify the code such that it sends us release failure notifications as well? Thank you.

I am using rails 3 and for one of the use cases, I need to detect a change in a hash field. I am making changes to the f attribute which is a hash inside the hash attribute. Something like this: Table.field = {:e=> 'hello', :f=> {"new_field"=>"In progress"}} So when I make changes to new_field it's not reflecting in previous_changes method or changes method in after_update callback. I need to trigger a few events based on this. However, it always gives {}. I tried to replace the whole field with a different value and that change is detected. Is there any other method that we can use to detect hash changes?
so i have users ,airlines and review .An airline has_many :reviews has_many :users,through: :reviews.A user has_many :reviews has_many :airlines,through: :reviews and a review belongs to an airlines and user.A user can experience multiple airlines.I dont understand a way to get all the reviews of a user of travelling by a particular airline.
here is my seed data
singapore_airlines=Airline.create(name: 'Singapore Airlines')
cathy=User.create(name:"Cathy",email:"cathy@jetsetgo.com",admin:false)
Review.create(image:"https://worldofwanderlust.com/wp-content/uploads/2022/03/866D61D2-FFD1-4392-9596-0E4E372D18D9.jpg", date: DateTime.new(2021, 11, 1),destination:"Singapore to Tokyo",seat:"Business class",description:"If you want comforting long flights always take Singapore airlines",likes:0,dislikes:0,airline_id:singapore_airlines.id,user_id: cathy.id)
so im aware in the console i can do something like sing=Airline.find(1) and then sing.reviews.........but that will give me all the reviews of singapore airline. i want only the review given by cathy.
I am struggling with the following problem: I want to have two different tabs, one that displays all recent chugs (Done), and one that displays the chugs that are the fastest per person.
However, this needs to remain an ActiveRecord, since I need to use it with link_to and gravatar, thus restraining me from group_by, as far as I understand it.
AKA: If there are three users who each have three chugs, I want to show 1 chug per user, which contains the fastest time of that particular user.
The current code looks like this, where chugs_unique should be edited:
def show
@pagy, @chugs_all_newest = pagy(@chugtype.chugs.order('created_at DESC'), items: 10, page: params[:page])
@chugs_unique = @chugtype.chugs.order('secs ASC, milis ASC, created_at DESC').uniq
breadcrumb @chugtype.name, chugtypes_path(@chugtype)
end
In this case, a chug belongs to both a chugtype and user, and the chugtype has multiple chugs.
Thanks in advance!
