添加新的设计用户类型会在Devise :: SessionsController #new中创建ArgumentError

I'm using rails 4.2 and devise 3.4.1

我正在使用rails 4.2并设计3.4.1

I've got a devise user type called entrant which is working fine. I've customised it slightly with a custom controller called registration.

我有一个名为entrant的设计用户类型,工作正常。我用一个名为registration的自定义控制器稍微定制了它。

I've added a new user type called admin like this

我添加了一个名为admin的新用户类型

rails generate devise Admin
rake db:migrate 

Then I've generated the views with

然后我用它生成了视图

rails generate devise:views admins 

When I visit the sign in URL for admins (/admins/sign_up) I get the following error

当我访问admins的登录URL(/ admins / sign_up)时,出现以下错误

ArgumentError in Devise::RegistrationsController#new
wrong number of arguments (2 for 1)

Extracted source (around line #466):
    args = key[-2, 2]

I've restarted my rails server, but I've no idea what else to do. Does anyone know why I'm getting this error. I also get the same error for other routes like /admins/sign_in

我重启了我的rails服务器,但我不知道还能做什么。有谁知道为什么我收到这个错误。对于/ admins / sign_in等其他路由,我也会遇到同样的错误

I've done this successfully before with other versions of Rails and Devise and its worked fine.

我之前使用其他版本的Rails和Devise成功完成了这项工作,并且工作正常。

Here is my routes.rb file

这是我的routes.rb文件

Rails.application.routes.draw do

  resources :entries
  devise_for :entrants, :controllers => { registrations: 'registrations' }
  resources :charges
  devise_for :admins
  # The priority is based upon order of creation: first created -> highest priority.
  # See how all your routes lay out with "rake routes".

  # You can have the root of your site routed with "root"
  root 'home#index'
end

Here is the registrations_controller.rb

这是registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController

  private

  def sign_up_params
    params.require(:entrant).permit(:first_name, :last_name, :email, :password, :password_confirmation)
  end

  def account_update_params

  def after_update_path_for(resource)
    #edit_entrant_registration_path(resource)
    entries_path

  def after_sign_up_path_for(resource)
    edit_entrant_registration_path(resource)

I'm not an expert so I can't give you the exact reason why you and me both were having this problem but --

我不是专家,所以我不能告诉你为什么你和我都有这个问题的确切原因但是 -

I was getting this line in the application trace, just like you:

我在应用程序跟踪中得到了这一行,就像你一样:

warden (1.2.3) lib/warden/session_serializer.rb:34:in `fetch'

After some digging, I figured out the problem was with the current session, so I opened up a new 'incognito' browser window and the error was gone.

经过一番挖掘,我发现问题出在当前会话中,所以我打开了一个新的“隐身”浏览器窗口,错误消失了。

You should be able to solve this problem by erasing your cookies and history from your browser.

您应该可以通过从浏览器中删除Cookie和历史记录来解决此问题。

I have no idea why this worked, but it must have been a conflict with versions or something.

我不知道为什么会这样,但它肯定是与版本或其他东西的冲突。

I reinstalled RVM, then installed ruby 2.2.2 and Rubygems 2.4.6 then reinstalled rails and it works now with devise 3.4.1

我重新安装了RVM,然后安装了ruby 2.2.2和Rubygems 2.4.6,然后重新安装了rails,它现在可以使用设计3.4.1
