How to set up two models having a has_many association with each other
- by daz13
I'm looking for a suggestion on how to set up two models, Teacher and Subject. A Teacher can have many Subjects, and a Subject can have many Teachers. Another thing to consider in the relationship between the two models is that a Teacher can create a Subject and add other Teachers to the Subject.
I think I'm solid on the basics of the set up for each model:
for teacher.rb:
has_many :subjects
for subject.rb:
has_many :teachers
and the teachers table should have a subject_id column and the subject table should have a teacher_id column.
What I'm not sure about is how to set up the views (and corresponding controller methods) to allow the addition of a Teacher to a Subject.
Any suggestions (or links to examples) are greatly appreciated. I haven't been able to find anything on this exact case.
