I have the following schema.
table: user
t.column :id, :integer
table: friends
t.column :user_id, :integer #Owner of this friendship
t.column :friend_id, :integer #FK to User table
table: activity
t.column :user_id
Basically I want to display all activity from friends that i have
I currently have the following has_many finder...
has_many :friend_activities,
:class_name => 'Activity',
:finder_sql => 'select a.* from activities a, friend f where
a.user_id = f.friend_id and f.user_id = #{id}'
Is it even possible to change the above has_many to not user
the :finder_sql but using some combination
of :through, :source ... ???? If so can someone please help.
