This might be a simple user->role->permission type setting. I can pick up that from a tutorial. But... really I need a deffinate combo of the three. So... If I have a movie with a director, theoretically there can be as many directors to this movie as there are persons, who are directors... I need jut THE ONE. So I need a movies_jobs_persons table I guesss...
I have an interesting task: 3 Tables: movies,people,jobs
Every movie has many people in it and every person does a certain job (some people do more than one, and some jobs are done by more people... aka: Robert De Niro is the actor and a director, but we have several other actors in the same movie)
Here is what I need to do:
class Person < ActiveRecord::Base
has_and_belongs_to_many :movies has_and_belongs_to_many :jobs
end class Job < ActiveRecord::Base
has_and_belongs_to_many :movies has_and_belongs_to_many :people
end class Movie < ActiveRecord::Base
has_and_belongs_to_many :jobs has_and_belongs_to_many :people
Is this sort of thing legal? I mean, do I get multiple Cartesian products that will eventually kill my application? Am I thinking the right way at all?
Thanx for any input.
