Rails：功能测试中的工厂和协会

Question

I'm trying to figure out why this doesn't work.

Let's say you three models, User, Foo and Bar. In order for a bar to be created the user must first create and validate a foo object.

Class User #snip!
has_many :foos
has_many :bars

Class Foo #snip!
belongs_to :user
has_many :bars

Class Bar #snip!
belongs_to :user
belongs_to :foo

I'm trying to get a functional test working where if the user tries to make a new Bar without having a valid foo, they get redirected to the "new" action for a Foo.

I haven't had any problem with the redirect scenario. However, when I try to setup a user with a valid Foo object and try to get the "new" action for a Bar, it still gets redirected to the "new" action of the Foo controller. It still doesn't acknowledge that the User has a Foo.

Here's my controller:

 class BarsControllerTest < ActionController::TestCase
  setup :activate_authlogic
  def setup
    @request.env['HTTPS'] = nil
    @user = Factory.build(:user)
    @foo = Factory.build(:foo, :user => @user)
  end
   test "should get new when user has a valid foo" do
     @request.env['HTTPS'] = 'on'
     UserSession.create(@user)
     get :new
     assert_response :success
  end

This is the redirect function I have in my application controller which is called in my bar controller:

  def foo_required
    if current_user && @current_user.foos.valid.empty? && @current_user.foos.empty?
    flash[:notice] = "You must have a verified foo in order to create a Bar!"
    redirect_to new_foo_path
    elsif current_user && @current_user.foos.valid.empty?
    flash[:notice] = "You must verify your foos in order to create a Bar!"
    redirect_to foos_path
    end
 end

Here's the Foo Factory:

Factory.define :foo do |f|
   #attributes
   f.valid true
   f.association :user
end

Instead I get redirected to " https://test.host:80/foos/new " The controller doesn't acknowledge that the user has a Foo...

The session is valid so this seems like a factory problem, but I'm not sure what it is.

I'm assuming that this is factory_girl. You are calling Factory.build which doesn't save anything to the database, so you never have the foreign key value needed for your association. Switch those to Factory.create and you should see a difference.
