How to identify a polymorphic relationship with a factory girl

I have custom and story models that have comments.

I announced the following models as shown below:

class Comment
  belongs_to :commentable, polymorphic: true
  belongs_to :user
end

class User
end

class Story
end

Now I want to declare a comment object with FactoryGirl, which belongs to the same user who deserves praise and as a user.

Here is my code:

FactoryGirl.define do
  factory :user do
    sequence(:email) {|n| "person#{n}@exmaple.com"}
    sequence(:slug) {|n| "person#{n}"}
  end

  factory :comment do    
    occured_at { 5.hours.ago }
    user
    association :commentable, factory: :user
  end

end

The problem is that the user who writes the comment and the commendable user is not the same.

Why should I fix this?

First of all, I don’t think you have already set up your associations ... I think this is what you want:

class Comment < AR
  belongs_to :commentable, polymorphic: true
end

class User < AR
  has_many :comments, as: :commentable
end

class Story < AR
  has_many :comments, as: :commentable
end

See: http://guides.rubyonrails.org/association_basics.html#polymorphic-associations
