[英]RSPEC and factory girl SystemStackError: stack level too deep
I have trying to solve an issue with my Spec tests and I get the following error Failures: 我试图解决我的Spec测试的问题,我得到以下错误失败:

Prior to this I had problems with associations with my factories. 在此之前,我与工厂的关联存在问题。
Factory.define :role do |role|
role.name "Registered"
role.association :user, :factory => :user
end
Factory.define :admin do |role|
role.name "Admin"
role.association :user, :factory => :user
end
Factory.define :user do |user|
user.first_name "Foo"
user.last_name "Bar"
user.email "foo@bar.com"
user.password "foobar"
user.password_confirmation "foobar"
user.status "At foobar"
user.description "Lorem Ipsum sit dolor amet."
user.username "foobar"
user.association :role, :factory => :role
user.association :admin, :factory => :role
end
Factory.define :user_with_admin_role, :parent => :user do |user|
user.after_create { |u| Factory(:role, :user => u) }
end
Factory.define :reg_user do |user|
user.first_name "bar"
user.last_name "foo"
user.email "bar@foo.com"
user.password "foobar"
user.password_confirmation "foobar"
user.status "At foobar"
user.description "Lorem Ipsum sit dolor amet."
user.username "barfoo"
user.association :role, :factory => :role
end
and my session tests so far are: 到目前为止我的会话测试是:
describe "POST 'create'" do
describe "invalid signin" do
before(:each) do
@attr = { :email => "email@example.org", :password => "invalid" }
end
it "should re-render the 'new' page with a flash error" do
post :create, :session => @attr
flash.now[:error] =~ /invalid/i
response.should render_template('new')
end
end
describe "with valid email and password" do
before(:each) do
@user = Factory(:user)
@attr = { :email => @user.email, :password => @user.password}
end
it "should sign in the user" do
post :create, :session => @attr
controller.current_user.should == @user
end
end
end
I am really not sure what is creating the problem. 我真的不确定是什么造成了这个问题。 In my model I assign a default role to every user as "Registered" and the "Admin" role for the first user. 在我的模型中,我将默认角色分配给每个用户为“已注册”,并为第一个用户分配“管理员”角色。
user.rb user.rb
def assign_default_role
if User.count == 0
self.roles << Role.find_by_name("Admin")
self.roles << Role.find_by_name("Registered")
end
self.roles << Role.find_by_name("Registered") unless User.count == 0
end
Any advise would be most welcome. 任何建议都是最受欢迎的。 Thanks 谢谢
The problem line is this: 问题是这样的:
@user = Factory(:user)
You have a circular reference: your :user
factory creates a :role
and :admin
factory. 您有一个循环引用:您的:user
factory创建:role
和:admin
factory。 Then the :role
and :admin
factories each create another :user
factory, which then creates yet another :role
and :admin
factory, and so on until you get a stack level too deep error. 然后:role
和:admin
工厂分别创建另一个:user
factory,然后创建另一个:role
和:admin
factory,依此类推,直到你得到一个堆栈级太深的错误。
You'll need to remove the associations from some of these. 您需要删除其中一些关联。 I'd recommend removing the role.association
lines from both :role
and :admin
. 我建议从:role
和:admin
删除role.association
行。 Whenever you create a :user
, it will still create the :role
and :admin
lines for you. 每当您创建一个:user
,它仍会为您创建:role
和:admin
行。
