Module: FactoryGirlExtensions

Defined in:
lib/factory_girl_extensions.rb

Overview

Adds helpful factory_girl methods to objects.

This uses method_missing just incase the given Object already responds to one of these methods.

Usage

User.generate!             # this is equivalent to Factory(:user) or Factory.create(:user)
User.gen!                  # this is a shortcut alias for #generate
User.generate              # this is equivalent to Factory.build(:user) and then #save
User.gen                   # this is equivalent to Factory.build(:user) and then #save
User.build                 # this is equivalent to Factory.build(:user)
User.gen! :name => 'Bob'   # this is equivalent to Factory(:user, :name => 'Bob')
:email.next                # this is equivalent to Factory.next(:email)
'email'.next               # this will NOT work because String#next already exists
:admin_user.gen!           # this is equivalent to Factory.gen(:admin_user)
'admin_user'.gen!          # this is equivalent to Factory.gen(:admin_user)
User.attrs                 # this is equivalent to Factory.attributes_for(:user)
'user'.attrs               # this is equivalent to Factory.attributes_for(:user)
:user.attrs                # this is equivalent to Factory.attributes_for(:user)

TODO

  • properly implement respond_to?

  • add syntax like User.gen_admin or User.gen(:admin) for generating an :admin_user
