ruby on rails - Is it the correct way to implement belongs_to relation with factory girl? -

i have realy easy model. user have role_id depends of role table (id, name) role reference.

i want create users of types on rspec test, factory girl.

my first idea

factory :role   name "guest"   factory :role_admin     name "admin"   end   factory :role_supervisor     name "supervisor"   end   etc... have lot different roles end    factory :user   email   password '123456'   password_confirmation '123456'   association :role, factory: :role    factory :admin     association :role, factory: :role_admin   end   factory :supervisor     association :role, factory: :role_supervisor   end   etc... have lot different roles end 

in model have simple method :

def is(role_name)    return self.role.name == role_name end 

it's correct way to? realy need create factory role? can make stub function in factory girl each role?

i realy new test stuff, thanks.

factories should reflect models.

class user   has_many :products end  class product   belongs_to :user end  factory :user   products end  factory :product end 

if want have special cases (understand roles in case) can define traits:

factory :user    traits :admin   end    factory :admin_user, traits: [:admin]  end 

more information on traits here.
