Association in Rails 3

I have three models User, Supplier, Company. There is One to Many relationship between User and Supplier and, Company and Supplier (a user has many supplier but a supplier belongs to one user). What would be right way to create such association in Rails 3? Also a User has_many Courses through UserCourses

If Courses is another model along with User,Company and Supplier, then following should work.

User: has_many :suppliers has_many :user_courses has_many :courses, :through => :user_courses

Supplier: belongs_to :user belongs_to :company

Company: has_many :suppliers

Courses: has_many :user_courses has_many :users, :through => :user_courses

If I got you correctly, it should be something like this:

User:

has_many :suppliers
has_many :user_courses
has_many :users, through: :user_courses

Supplier:

belongs_to :user
belongs_to :company

Company:

has_many :suppliers
