Question

In the Rails documentation, we find the following example:

class Physician < ActiveRecord::Base
  has_many :appointments
  has_many :patients, :through => :appointments
end

I’m just curious: is it possible to generate this via the command line using rails generate model?

Answer 1

Not according to the usage message you get from rails generate model. You can set up a belongs_to relationship, though:

rails generate model photo title:string album:references

Gives me the following in app/models/photo.rb:

class Photo < ActiveRecord::Base
  belongs_to :album
end
