Relationships code challenge 2: Problem

Hello,

i have a problem with the related code challenge.

The challenge Task is:

Let's say we have a BlogPost model and a Comment model
that represents comments someone might leave on a blog
post. The comments table includes a blog_post_id column.
Please setup the relationships correctly.

Here is my code:

class BlogPost < ActiveRecord::Base
  has_many :comments
end

class Comment < ActiveRecord::Base
  belongs_to :blogpost
end

I think my code is correct but the error message says:

Bummer! Remember, `belongs_to` always wants the
singular version of the relationship.

Thanks

You need an underscore:

belongs_to :blog_post
Maciej Czuchnowski
Maciej Czuchnowski
36,441 Points
Maciej Czuchnowski

When the model has name like this: BlogPost you can assume that there will be an underscore before post. Also, the name of the column was blog_post_id, so it HAS TO take blog_post.
