已解决。Rails 中有一个 bug。请参见 https://github.com/rails/rails/issues/2333
我在使用 Factory Girl Rails 和 Rails 3.1.0.rc5 时遇到了问题。
当我执行多次 user = FactoryGirl.create(:user)
时,会出现错误。
Failure/Error: user = FactoryGirl.create(:user)
NameError:
uninitialized constant User::User
# ./app/models/user.rb:17:in `generate_token'
# ./app/models/user.rb:4:in `block in <class:User>'
# ./spec/requests/users_spec.rb:20:in `block (3 levels) in <top (required)>'
我可以使用Factory在Rails控制台中创建任意数量的用户。
测试:
require 'spec_helper'
describe "Users" do
describe "signin" do
it "should sign in a user" do
visit root_path
user = FactoryGirl.create(:user)
within("div#sign_in_form") do
fill_in "Name", with: user.name
fill_in "Password", with: user.password
end
click_button "Sign in"
current_path.should eq(user_path(user))
page.should have_content("signed in")
end
it "should not show new user form on /" do
user = FactoryGirl.create(:user)
visit root_path
page.should_not have_css("div#new_user_form")
end
end
end
factories.rb
FactoryGirl.define do
factory :user do |f|
f.sequence(:name) { |n| "john#{n}" }
f.fullname 'Doe'
f.sequence(:email) { |n| "test#{n}@example.com" }
f.password 'foobar'
end
end
model/user.rb
class User < ActiveRecord::Base
has_secure_password
attr_accessible :name, :fullname, :email, :password
before_create { generate_token(:auth_token) }
email_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
validates :name, presence: true, length: { maximum: 20 },
uniqueness: { case_sensitive: false }
validates :fullname, presence: true, length: { maximum: 30 }
validates :email, format: { with: email_regex },
uniqueness: { case_sensitive: false }, length: { maximum: 30 }
validates :password, length: { in: 5..25 }
def generate_token(column)
begin
self[column] = SecureRandom.urlsafe_base64
end while User.exists?(column => self[column])
end
end
User.exists?(column => self[column])
导致了问题。
该代码导致了问题。
setup
方法中创建用户。然后它就可以在所有后续测试中使用了。 - MrDanA
