Hi everyone.
I’ve got the following in my model:
class Newsletter < ActiveRecord::Base
has_and_belongs_to_many :tags
def tag_attributes=(tag_attributes)
tag_attributes.each do |attributes|
tags.build(attributes)
end
end
end
class Tag < ActiveRecord::Base
has_and_belongs_to_many :newsletters
end
And I also got a newsletters_tags relationship table in my DB,
containing newsletter_id and tag_id (both fields are set as
primary_key)
How do I perform a search to retrieve every tag within a particular
newsletter, or all newsletters that relates to an specific tag?
