- What's this?
scope_chain()
public
Consider the following example:
class Person has_many :articles has_many :comment_tags, through: :articles end class Article has_many :comments has_many :comment_tags, through: :comments, source: :tags end class Comment has_many :tags end
There may be scopes on Person.comment_tags, Article.comment_tags and/or Comment.tags, but only Comment.tags will be represented in the #chain. So this method creates an array of scopes corresponding to the chain.
