has many... more

Hello there,

a Person has_many projects, and a Project has_many tasks. Thus, a Person also has many tasks.

Is there a way to write this has_many in the Person class without using :finder_sql?

Thanks a bunch in advance! Giuseppe

class Task < ActiveRecord::Base belongs_to :project end

class Project < ActiveRecord::Base belongs_to :person has_many :tasks end

class Person < ActiveRecord::Base

has_many :projects has_many :tasks, :through => :projects end

DUH! I had always thought that :through would only apply to a model that belongs_to the other two (like a join table).

I should have tried this before going to the forum.

Thanks Rick, Giuseppe
