Rails RESTful to delete in nested resources

Question

Ok, so here is an example script. There is a student resource resources :students, and students have and belong to many collections: resources :clubs, resources :majorsetc.

This way we can easily customize our routes ...

resources :clubs do
  resources :students
end
resources :majors do
  resources :students
end
resources :students do
  resources :clubs
  resources :majors
end

which generates us a bunch of standard RESTful routes

• / clubs
• / clubs /: identifier
• / clubs /: club_id / students
• / clubs /: club_id / students /: id of majors
• / majors /: identifier
• / majors /: major_id / students
• / majors /: major_id / students /: identifier
• / students
• / students /: identifier
• / students /: student_id / clubs
• / students /: student_id / clubs /: identifier
• / students /: student_id / majors
• / students /: student_id / majors /: identifier

Answer 1

, RESTful aproach has_many :through . , .

resources :majors do
