Questions[ruby-on-rails]

From the current time, I need to validate that it is greater than 24 hours:

• hora_pedidoIt's starting time.
• hora_entregait's final hour.

From the parent model, there is an attribute called hora_pedido; model:

class Reunion < ApplicationRecord

 #maestro de detalle 
 has_many :detalles_reuniones, :dependent => :destroy
 accepts_nested_attributes_for :detalles_reuniones, allow_destroy: true

 def detalles_reuniones_for_form
   collection = detalles_reuniones.where(reunion_id: id)
   collection.any? ? collection : detalles_reuniones.build
 end


     #El metodo que asigna los valores
    before_validation :asignar_valores_por_defecto_reunion

   def asignar_valores_por_defecto_reunion
    Time.zone = "America/Bogota"
   self.hora_pedido = Time.zone.now.strftime("%Y-%m-%d-%H:%M:%S" )
 end

Of the child model, there is an attribute called hora_entrega; class model

class DetalleReunion < ApplicationRecord

    #Asociaccion por maestro de detalle
    belongs_to :reunion, optional: true

   validate :validar_horas 

   def validar_horas
     if ( hora_entrega - ( 60 * 60 * 24 ) ) >= ( reunion.hora_pedido )
     # Código cuando se cumple la condición
     else
      errors.add(:hora_entrega," La entrega debe ser mayor a 24  horas  ")
    end
   end       
end

The two attributes are of type Time:

• hora_pedido=Time
• hora_entrega=Time

It is a master detail, there are two forms filled at the same time, so in the parent table there is an attribute that is hora_pedido, this would be the current time and in the child table there is an attribute that is hora_entregathe time, to define the one that is greater than 24 hours, the parent table is called reunionand the child table is called detalle_reunion.

I have updated all the code :

I do this in my edit, update, destroy functions

@post = Post.friendly.find(params[:id])
if @post.user_id == current_user.id

Is there any way to optimize and make a single function, before I did it this way:

before_action :set_user_post, only: [:edit, :update, :destroy]

private
def set_user_post
  @post = current_user.posts.find_by(id: params[:id])
end

But add the friendly_id gem and modify it like this:

private
def set_user_post
  @post = current_user.posts.friendly.find(id: params[:id])
end

But it gives me an error.

I'm just starting out on Rails and haven't been able to find a relationship.

I have 3 tables: Video, donations and users. A user can put X videos and each video can have several donations.

• In video I haveuser_id
• In Donations I have the user_idandvideo_id

My models are:

class Donation < ActiveRecord::Base
  belongs_to :user
  belongs_to :video
end

class Video < ActiveRecord::Base
  belongs_to :user
  has_many :donation
end

class User < ActiveRecord::Base 
  has_many :video
  has_many :donation
end

I can get the user of each video without problems:

video.user.name 

The problem occurs when I want to get the title of the video of a donation:

 <% @donaciones.each do |d| %>
      <%= d.video.titulo %><br>
 <% end %>

always gives me:

undefined method `titulo' for nil:NilClass

The title is in the table videos, I only have 1 record.

Is there a way to be able to see the full query being performed on the error page?

I am testing for a API en RoR. I want to validate the structure of a response to a request from my API. I want to make sure that a particular field exists in that response and if it doesn't exist indicate that the test fails.

let(:user) { FactoryGirl.create(:user) }

describe "POST #create" do

    context "when logged in with identifier" do

        before(:each) do
            @user_attributes = { identifier: user[:email], password: '12345678' } 
            post :create, { session: @user_attributes }
        end

        it"when is valid token" do
            #como valido que en la respuesta exista el token
        end
    end
end

The responsepetition is as follows:

{"user": 
  {
   "id":9005,
   "email":"[email protected]",
   "first_name":"Serenity",
   "middle_name":"Keagan",
   "last_name":"O'Kon",
   "birthday":"2014-07 -01T04:30:00.000Z"
  },
 "token":"....."
 }

I am using RSpec 3.3.0andRails 4.2.3

How do you go about displaying a Rails view without displaying the app layout for a logged in user and another layout for a visitor? It can?
