Rails includes nested relations

Question

I need to query all posts from a specific user and include all comments and the user who belongs to the comment.

class User < ...
  has_many :posts
  has_many         


        

Answer 1

How about include at the relation definition statement?

:include
Specify second-order associations that should be eager loaded when this object is loaded.

class Post <
  belongs_to :user
  has_many :comments, :include => [:user], :limit => 5
end
