How can I detect any bot scripts in a huge project?

It is a huge project. There are many other developers too. The project is made on ruby on rails. Many of its modules are made in javascript. I want to detect bots and I haven't found any method to do that.

returning the array created on a function to the initialize of a other function object

I'm making a simple "sell, client" program to practice in Ruby and I'm on a dilem taking the code, how is it possible to add the "itemsell" from the function "selecproduct" to the last argument on the init of object Venda (just where I tagged ##HELP##)

I'm having no problem in the process of add a Object as a variable, I'm just having the problem to return that value on one function to another one

def manipvendas
  while true
    puts "\n1- Adicionar venda"
    puts ""
    escolha = gets.chomp
    return if escolhe == "0"

    if escolha == "1" #adicionar venda
      print "\nInsira o número da venda: "
      numvend = gets.chomp
      numvend = numvend.to_i
      print "\nInsira a data da venda (Ano, Mês, Dia): "
      ano = gets.chomp
      mes = gets.chomp
      dia = gets.chomp
      data = Time.new(ano.to_i, mes.to_i, dia.to_i)
      print "\nInsira o cliente (número pela ordem cadastrada) para o qual a venda foi feita: "
      clientenum = gets.chomp
      selecproduct
      vendai = Venda.new(numvend,data,clientenum,##HERE##)
      @vendas.push(vendai)
    end
  end
end

def selecproduct
  while true
    print "\nInsira o produto (número pela ordem cadastrada) vendido: "
    print "Insira -1 para encerrar"
    produtonum = gets.chomp
    return if produtonum == "-1"
    print "\n Insira a quantidade do produto vendida: "
    produtoqnt = gets.chomp
    valor = produtoqnt * @produtos[produtonum].get_valor
    itemsell = ItemVenda.new(produtonum, @produtos[produtonum].get_valor, valor)
    @itemvenda.push(vendaitem)
  end
end

Query in rails with where array clause

I have an array field, author_ids in books table, I need to write a query to find the array data.

Is there any way i can get, even if author_ids has [1,3] in its value, but when I check with array [1,5], I still could get the data because it has 1 common ? here('author_ids @> ARRAY[?]::integer[]',[1,5])

where('author_ids @> ARRAY[?]::integer[]',[1,5])

this doesnot return data, where('author_ids @> ARRAY[?]::integer[]',[1,3]) whis does because It has [1,3]. Iwant to get the data where [auther_ids] ? any [passed_aray]

I am debugging the each and every line of the code. Is this might be the reason for the occurrence of this error? If so then how can I debug the code?

For the eval_orchestration method, there is no method call but in the rails server this method is being hitted. Where the method call is happening?

module Va::OrchestrationNode
  include Va::OrchestrationConstants
  include Workflow::FunctionalDataUtil
  include Va::Util
  include Marketplace::ApiActions
  include Metering::Helper
  include Workflow::FunctionalNodesUtil
  include Workflow::OsrCommonMethods

  def eval_orchestration(node, evaluate_on)
   ######statements#
  end
end

While running the server there is no call to the above method but in server it is hitting the lines in the eval_orcheatration method. It will be helpful for me if someone explains what is going on here?

Ruby : Cannot load such file --ruby2d (LoadError)

Returning to functions but having to access arrays created only on main, how to?

I'm making a very simple code here to practice with Ruby and going to implement a simple "client, product, sell" interface

def menuinicial
    print "1 - Cliente
2 - Produto
3 - Venda
0 - Sair do programa
insira o código de manipulação desejado: ";
end 

here is the initial menu

def manipclientes
    while true
    puts "\n1 - Adicionar cliente"
      puts "2 - Visualizar clientes cadastrados"
      puts "3 - Editar cliente"
      puts "4 - Remover cliente"
      puts "0 - Retornar ao menu anterior"
      print "\nInsira a opção desejada: "
      escolha = gets.chomp
      return if escolha == "0"
      
      if escolha == "1" # "Adicionar cliente"
        print "\ninsira o nome do cliente: "
        nome = gets.chomp
        print "\ninsira o endereço do cliente: "
        rua = gets.chomp
        print "\ninsira o RG do cliente: "
        rg = gets.chomp
        print "\ninsira a data de nascimento do cliente( Ano, mês, dia): "
        ano = gets.chomp
        mes = gets.chomp
        dia = gets.chomp
        data = Time.new(ano.to_i, mes.to_i, dia.to_i)
        a = Cliente.new(nome, rua, rg, data)
        clientes.push(a)        #adicionando a ao array
      end

here is part of the code that is having issue, just right when I try to use the "Client.new" returns me the error

"in manipclientes': undefined local variable or method `clientes' for main:Object (NameError)"

and below there's the main code partially ready to go

# main
while true
menuinicial
init = gets.chomp
  break if init == "0"
  manipclientes if init == "1"
  manipprodutos if init == "2"
end

I can get the code working when I don't place it in "functions" but then I can't return to the initial menu (I've made a post right here)

How can I render multiple resources in one API request?

This is what I am trying to achieve

"Add a RESTful, read-only API to allow consumers to retrieve Questions with Answers as JSON (no need to retrieve Answers on their own). The response should include Answers inside their Question as well as include the id and name of the Question and Answer users."

So far I have my controllers set up as follows:

class Api::V1::UsersController < ApplicationController

def index
    @users = User.all 
    render json: @users 
end

def show
    @user = User.find(params[:id])
    render json: @user 
end

end

class Api::V1::QuestionsController < ApplicationController

def index
    @questions = Question.where(share: true) 
    render json: @questions
end

end

class Api::V1::AnswersController < ApplicationController

def index
    @answers = Answer.all 
    render json: @answers 
end

end

And my routes are set up like this however I'm sure this is not correct for what I want to achieve

Rails.application.routes.draw do

namespace :api do namespace :v1 do resources :questions do resources :answers do resources :users end end end end

root 'welcome#index'

get 'welcome/index' end

Any help would be appreciated

session.inspect output with propper indentation in rails

Using p session.inspect outputs a single line. I want to add a html-container in my application view, always showing what's inside the session. But this should be properly formatted with indentations and breaks. Is there a way to achieve this?

In PHP, e. g., you can wrap the output of $_SESSION in a <pre>-tag and it will automatically be properly formatted.

Query on JSONB column to extract records between 2 dates

I am struggling to write a query in a Rails model which will retrieve all records with the date between two dates( dynamic dates from UI input).

The column is a jsonB column looking like this:

"170"=>[{"name"=>"Conflict Date/Time", "value"=>"2022-04-14 14:51:29", "valueUTC"=>"2022-04-14 13:51:29"}],

This record should be a valid one returned for a search with start_date: "2022-04-12 13:22:55" end_date: "2022-04-18 16:11:22".

What i got so far? This query:

where("short_response->>'#{item_id}' ~* ?", "\"value\": BETWEEN #{start_date} AND #{end_date}")

Thank you! Any help will be appreciated.

Finding a weird symbol in Capybara

I'm currently trying to find a symbol on a page. I have the HTML tag and the find method that I'm using. However it's not able to find this symbol. I'm not sure what I'm doing wrong to do so.

<div class="ui-grid-selection-row-header-buttons ui-grid-icon-ok clickable bg-pristine bg-valid bg-scope bg-not-empty bg-touched" bg-class="{'ui-grid-row-selected': row.isSelected}" tabindex="0" bg-click="selectButtonClick(row, $event)" bg-keydown="selectButtonKeyDown(row, $event)" role="checkbox" bg-model="row.isSelected" aria-checked="true" aria-invalid="false">&nbsp;</div>

As you can see this is a weird html tag. I'm trying to avoid full xpath if possible.

Here is what I"m doing.

find(:css, "ui-grid-selection-row-header-buttons[button = 'selectButtonClick']")

Why 0.0 throws can't be blank?

If I work with this code, and I enter 0.0 (or 0), why does it throw xyzzy can't be blank

validates :xyzzy, numericality: { greater_than_or_equal_to: 0, less_than: 100 }, allow_blank: true

Please help!

Ruby on Rails - Generate POST request without refreshing the page

I am creating an e-commerce website with Ruby on Rails and there is something bothering me.

I have a product card with a link. If the user clicks the link, the product goes into the cart. I used remote: true so that it allows to generate the POST request without refreshing the page:

<%= link_to order_items_path(product_id: product), remote: true, method: :post do %>
      <i class="fas fa-shopping-cart"></i>
    <% end %>

But it always ends up refreshing the page and scrolling to the top of the page. Am I missing something?

And if it is not like this how it works, how could I make it do what I want?

Just for reference, the link goes to the OrderItemsController#create:

def create
        @order = OrderItem.generate_order(current_user)
        if order_items_params
            @order_item = OrderItem.new(order_items_params)
        else
            @order_item = OrderItem.new(quantity: 1, product_id: params[:product_id])
        end
        @order_item.order = @order
        authorize @order_item
        if @order_item.save
            redirect_to edit_order_path(@order)
        else
            redirect_to root_path, notice: "Product not ordered, please try again"
        end
    end

Thanks!

How to make a subtraction between 2 records from the same column using rails?

Hi Stackoverflow team.

I'm using ruby on rails and i'm trying to find the code to make a subtraction between 2 records from the same column using rails.

I have the following table

customers
    id    num_hid     num_oxi
    1        1           2
    2        3           4
    3        5           6
    4        7           8

I'm trying to get this result

 @result =  last_num_hid_id_4 -  last_num_hid_id_3
 //calcultion is: 7-5 = 2

i did this code but this displays the last 2 records in array

<% @customers.each.last(2) do |customer|%> %>
  <%= customer.num_hid %>
<% end %>

i tried this code but is only showing the last record

@last_customer =Customer.all.last
@last.num_hid

Can somebody help me with this issue?

I will appreciate all your comments.

Thanks in advance.

Finding a button in Capybara

I'm trying to find this specific button. I've tried using find button in capybara to do this but I'm unable to.

find(:button, 'Open Cow menu').click

HTML Tag

<button class="cd-icon-button cd-button cd-irx-cyan-theme" type="button" ng-transclude="" aria-label="Open Cow menu" ng-click="$mdMenu.open($event)" aria-haspopup="true" aria-expanded="false" aria-owns="menu_container_1">
        <i class="fa fa-ellipsis-h" aria-hidden="true"></i>
    </button>

I'm sure there is a easier way of doing this.

Devise + Patreon OAuth in Ruby on Rails

I have implemented the devise+patreon gem in my Rails application without issues. Now, devise requires an email/password by default when creating a User, but Patreon just uses the oauth integration.

I am wondering, what is the proper strategy to use so that I can migrate the Patreon Oauth users as Devise users, without having to set dummy passwords/emails to allow for validation to go through. I still want to eventually allow users to register via Devise natively, as well as through Patreon.

Is there maybe a known strategy/gem/addition for devise that I may have missed that can easily achieve that?

Extracting images from multiple PDF files using hexapdf - hexapdf no such file or directory @ rb_sysopen

I'm in my master thesis and I have to extract images from about 500 pdf files, some people recommended hexapdf to me for this. I was able to install Ruby and hexapdf and now I'm kinda stuck getting the images out of the pdf's since I don't have a coding background. Any tips? Thanks in advance.

I tried using the basic command for only one pdf to see what happened by using 'hexapdf images' followed by the pdf name but the result was 'no such file or directory @ rb_sysopen'.
