NameError（未定义的局部变量或方法`devise_parameter_sanitizer'

I'm using devise for user authentication. However, when a user tries to create an account I am getting this error:

我正在使用设计进行用户身份验证。但是，当用户尝试创建帐户时，我收到此错误：

NameError (undefined local variable or method `devise_parameter_sanitizer'

This is what my devise registrations controller looks like:

这就是我的设计注册控制器的样子：

def sign_up_params
devise_parameter_sanitizer.for(:sign_up)
end

Any ideas?

有任何想法吗？

Thanks in advance

try to use rails4 branch

尝试使用rails4分支

Looking at the devise open issues on Github i found this: https://github.com/plataformatec/devise/issues/2372 - seem to do the trick for me. note that this is probably a rails 4 issue.

看看Github上的设计开放问题我发现了这个：https：//github.com/plataformatec/devise/issues/2372 - 似乎对我有用。请注意，这可能是一个rails 4问题。

For anyone who ends up here with error

对于任何最终错误的人

undefined method `<<' for {}:ActionController::Parameters

you need to upgrade to Devise 3.1.0.rc as in this comment
which basically means using master branch version

你需要升级到Devise 3.1.0.rc，就像在这个评论中一样，这基本上意味着使用master分支版本

gem 'devise', git: 'git://github.com/plataformatec/devise.git'

hope I help some lost souls as I was for last half an hour.

希望我像过去半小时那样帮助一些失去的灵魂。

The latest released Gem for Devise at the time of writing is 2.2.4. This does not include the devise_parameter_sanitizer method, hence the error you are seeing.

在撰写本文时，最新发布的Gem for Devise是2.2.4。这不包括devise_parameter_sanitizer方法，因此您会看到错误。

You are probably following the manual for Devise at https://github.com/plataformatec/devise. The section on Rails 4 and Strong Parameters has been added recently.

您可能正在访问设计手册，网址为https://github.com/plataformatec/devise。最近添加了关于Rails 4和Strong Parameters的部分。

You have a few options:

你有几个选择：

Get the latest master version of Devise using bundler, so that the devise_parameter_sanitizer method is available:

使用bundler获取最新的Devise主版本，以便devise_parameter_sanitizer方法可用：

gem 'devise', :git => 'git://github.com/plataformatec/devise.git'

gem'depaise'，：git =>'git：//github.com/plataformatec/devise.git'
Don't apply ActiveModel::ForbiddenAttributesProtection to your User model, so strong parameters are not even used. More info here: Devise and Strong Parameters

不要将ActiveModel :: ForbiddenAttributesProtection应用于您的用户模型，因此甚至不使用强参数。更多信息：设计和强参数
Override the required Devise controllers directly. See here: https://gist.github.com/kazpsp/3350730
