Luisepvs's questions

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?
