Hi,
I am trying to learn to use RoR by making a simple social networking
example. Given a user id, I am trying to make a query that finds all of
the group that user belongs to but also rank the groups by one of the
groups’ parameter like group.size. Pretend group.size is a number from
1-10 and is precalculated. Can I do this is one query? Here are the
relationships I set up:
class User < ActiveRecord::Base
has_and_belongs_to_many :groups
end
class Groupship < ActiveRecord::Base
set_table_name “users_groups”
belongs_to :recipes
belongs_to :tags
end
class Group < ActiveRecord::Base
has_and_belongs_to_many :users
end
Thanks!
