Question

我正在构建一个应用程序，我决定使用Devise和CanCanCan ..我已经设置了应用程序，只有管理员或超级用户才能添加新用户。

我的用户是从位于application.html.erb页面上的模式创建的。

我可以创建新用户没问题，一切正常。然而，现在我试图设置它，用户可以再次从模态编辑他们的个人资料..这是我“撞墙”的地方。

This is the github repo for this project feel free to take a look if you want to.

我一遍又一遍地经历过代码，但无济于事！

编辑＃1 - ScreenShot 这是我收到的错误消息。

No route matches {:action=>"update", :controller=>"admins"} missing required keys: [:id]

在你因为没有正确设置id而跳过我之前，我正在使用虚荣网址的SecureRandom.hex（6）字符串。除了这里，它们似乎在其他地方都很好。

表示编辑用户的rake路由输出。

       edit_user GET    /admins/:id/edit(.:format)        admins#edit
  push_edit_user PATCH  /admins/:id(.:format)             admins#update

这是routes.rb中的自定义路由

  as :user do
    get "admins/new_user" => "admins#new_user", as: :admins_new_user
    post "admins/create_user" => "admins#create_user", as: :admins_create_user

    get "admins/:id/edit" => "admins#edit", as: :edit_user
    patch "admins/:id" => "admins#update", as: :push_user_edit

end

这是我的用户（管理员）控制器，我有我的创建和更新操作。

class AdminsController < ApplicationController
  before_action :authenticate_user!

  def new_user
    authorize! :manage, User
    @user = User.new
  end

  def create_user
    @user = User.find_by_user_ident(params[:user_id])
    authorize! :manage, User
    @user = User.new(sign_up_params)
    if @user.save
      format.html { redirect_to root_path, notice: 'User has been successfully created.' }
    else

    end
  end

  def edit
    @user = User.find_by_user_ident(params[:user_id])
  end

  def update
    @user = User.find_by_user_ident(params[:user_id])

    if @user.update(account_update_params)
      format.html { redirect_to @user, notice: 'Address was successfully updated.' }

    else

    end
  end

  private

  def sign_up_params
    params.require(:user).permit(:email, :password, :password_confirmation, :user_ident, :f_name, :m_name, :l_name, :dob, :role)
  end

  def account_update_params
    params.require(:user).permit(:email, :password, :password_confirmation, :user_ident, :f_name, :m_name, :l_name, :dob, :role)
  end

  # Sets user to be found by User_Ident #
  def set_user
    @user = User.find_by_user_ident(params[:id])
  end

  # Allow Profile Update w/o Current p/w Confirmation
  def update_resource(resource, params)
    resource.update_without_password(params)
  end

end

并且为了安全起见，这里是错误的完整堆栈跟踪。

Answer 1

我认为您的错误来自Dim index As Integer = 0 Do Dim fileReader As String = My.Computer.FileSystem.ReadAllText(TextBox1.Text).Replace(index & " ", index) My.Computer.FileSystem.WriteAllText(TextBox1.Text, fileReader, False) index += 1 Loop Until index = 50。
