Rails 2.3: using another models named_scope inside another named_scope
- by mustafi
Hi
Let's say I have two models like so:
class Comment < ActiveRecord::Base
belongs_to :user
named_scope :about_x :conditions => "comments.text like '%x%')"
end
class User < ActiveRecord::Base
has_many :comments
end
How can I add a named_scope to the user model like so
class User < ActiveRecord::Base
has_many :comments
named_scope :comments_about_x, :includes => :comments, :comments_named_scope => :about_x
end
Which allows me to do
all_user_comments_about_x = User.comments_about_x
The reasoning is I often need to use the comment models about_x named scope logic but I don't want to have "comments.text like '%x%')" scattered around my code.
I hope this make sense :)
Thank you
