Rspec的故障在示例應用程序

Question

我稍早這些錯誤，我增加了

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

線user.rb和它似乎解決在發展我的示例應用程序某些功能問題，一切都進行得很順利。於是我決定把它推到Heroku的和不能正常工作，直到我從我的user.rb刪除

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

線。現在rspec失敗了。有什麼我失蹤？任何幫助表示讚賞。

' c:\Sites\sample_app>bundle exec rspec spec/ 
including Capybara::DSL in the global scope is not recommended!

Answer 1

你有你的spec

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

型號無效的許多錯誤，因爲不救

3) User when email address is already taken 

此錯誤是因爲模型不保存
瞭解valid？

valid?(context = nil)
運行所有指定的驗證和是否添加否則爲false沒有錯誤返回true。

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 

和這麼多隻是讀取錯誤
