在Rails中使用Devise gem时如何创建没有电子邮件和密码的用户？

Question

In my Rails app, Admins are the people who add users to the system. If the user doesn't have an email, a password won't be generated for him and he can't log in. But if the user have an email, a password will be generated. But the problem is, devise won't allow blank passwords. How can we fix this?

Answer 1

you can override them in your user model:

def password_required?
  false
end

def email_required?
  true
end

Edit:

def password_required?
   new_record? ? false : super
end
