ruby on rails - Rspec Controller Tests with an STI user model? -

i'm attempting write controller specs sub controller, in case admin::userscontroller

it has basic set of crud actions.

my users_controller_spec.rb

describe admin::carrierscontroller   before(:each)     sign_in factorygirl.create(:admin)   end    "should have current_user"     subject.current_user.should_not be_nil   end    describe "get 'index'"     "assigns users @users"       user = create(:user)       :index       assigns(:users).should eq [user]     end     "renders index view"       :index       expect(response).to render_template :index     end   end end 

now problem i'm running against index action. controller work , simple @users = user.all

whats complicating things user table sti so

class user < activerecord::base end class client < user end class seller < user end 

my factories

factorygirl.define   factory :user     name { faker::company.name }     sequence(:email) {|n| "test#{n}@test.com"}     password "password"     password_confirmation {|instance| instance.password }     type "seller"      factory :admin       type "admin"     end      factory :seller       type "seller"     end      factory :client       type "client"     end   end end 

obviously eq method not working becuase rspec has problems matching class names in assigns(:users) expectation. exact error is:

1) admin::userscontroller 'index' assigns users @users      failure/error: assigns(:users).should eq user        expected #<activerecord::relation [#<client id: 1282, name: "marks-kozey", type: "client"...]> eq #<user id: 1282, name: "marks-kozey", type: "client"... 

is problem factories? or testing incorrectly. first time testing sti appreciative.

try passing class symbol child factory, e.g.:

factory :client, class:client   type "client" end 

the factory-generated object should of type client instead of user.
