has_many通过了好几次

Question

我想听听关于我的代码的建议，因为我不太可能很好地使用has_many槽关联。

在我的情况下，用户可以标记为查看帖子。他们可以评论帖子，也可以写关于帖子的笔记。

这就是我所做的：

class User 
  has_many :posts, through: post_views
  has_many :posts, through: comments
  has_many :posts, through: notes
end
class Post
  has_many :users, through: post_views
  has_many :users, through: comments
  has_many :users, through: notes
end
class PostView
  belongs_to: user
  belongs_to: post
end
class Comment
  belongs_to: user
  belongs_to: post
end
class Note
  belongs_to: user
  belongs_to: post
end

可以吗？我能做些什么来获得更好的代码？

编辑=在Mohammad AbuShady回答之后类用户has_many:后期视图has_many:viewed_posts，通过：：post_views

  has_many :comments
  has_many :commented_posts, through: comments
  has_many :notes
  has_many :noted_posts, through: notes
end
class Post
  has_many :post_views
  has_many :viewer_users, through: post_views
  has_many :comments
  has_many :comments_users, through: comments
  has_many :notes
  has_many :notes_users, through: notes
end

class PostView
  belongs_to: user
  belongs_to: post
end
class Comment
  belongs_to: user
  belongs_to: post
end
class Note
  belongs_to: user
  belongs_to: post
end

还好吗？

您需要与连接模型建立关系才能使through零件工作，因此

class User < ActiveRecord::Base
  has_many :post_views
  has_many :viewed_posts, through: :post_views
end
class PostView < ActiveRecord::Base
  belongs_to :posts
  belongs_to :users
end
class Post < ActiveRecord::Base
  has_many :post_views
  has_many :users, through: :post_views
end

其他两款车型也是如此。
