My situation is like this. Company has many users and users may belongs to many companies. And current implementation is something like below.

  class Company 
    has_many :employments
    has_many :users, :through => :employments
  end

  class Employment 
    belongs_to :company
    belongs_to :user
  end

  class User
    has_many :employments
    has_many :companies, :through => :employments  #This doesn't looks correct
  end

It works, but "user has many companies" doesn't looks logically meaningful. It must be some thing like belongs_to_many companies. Do I need to use has_and_belongs_to_many?

Can some one please suggest the right way for representing these relationships?
