Question

我之前遇到过这些错误，并添加了

attr_accessible :name, :email, :password, :password_confirmation

排到user.rb，它似乎解决了我的示例应用程序在开发过程中的一些功能问题，一切都很顺利。然后我决定把它推到heroku，直到我删除了

之后才行

attr_accessible :name, :email, :password, :password_confirmation

从user.rb开始。现在rspec失败了。有什么我想念的吗？任何帮助表示赞赏。

including Capybara::DSL in the global scope is not recommended!

Answer 1

你的spec犯了很多错误

2) User Failure/Error: it { should be_valid }

模型无效，因为不保存

3) User when email address is already taken

此故障因为模型未保存
了解valid？

valid?(context = nil)
运行所有指定的验证，如果没有添加错误，则返回true，否则返回false。

my_person = Person.new(params[:person])
my_person.valid?
# => false

my_person = Person.create(params[:person])
my_person.valid?
# => true

my_person.errors.add('login', 'can not be empty') if my_person.login == ''
my_person.valid?
# => false

以及更多只读错误
