Organizing ActiveRecord links?

Question

Ruby on Rails

There are 3 models:

class Post < ActiveRecord::Base
  belongs_to :user
  has_many :likes, :dependent => :destroy
  has_many :users, through: :likes
end

class Like < ActiveRecord::Base
  belongs_to :user
  belongs_to :post	
end

class User < ActiveRecord::Base
  has_many :posts, :dependent => :destroy
  has_many :likes, :dependent => :destroy
  has_many :posts, through: :likes
end

Here's the problem:
When I try to get a list of a user's posts ( @user.posts), the script returns an array of liked posts. The same is true when deleting a user - only the "likes" of the user are deleted, but not the records of this user themselves.
How to remove this conflict of two associations and get the performance of both has_many and has_many :through ?

Answer 1

has_many :liked_posts, through: :likes, source: :article

Answer 2

has_many :liked_posts, through: :likes, class_name: 'Post'

Answer 3

The same is true when deleting a user - only the "likes" of the user are deleted, but not the entries themselves.

That is, if you wrote a post, I liked it, and then deleted my profile, then your work will sink into oblivion?
