试图阻止非管理员注册管理员

Question

我有一个简单的博客，我只希望管理访问创建管理选项和视图。我已经安装、设计和使用了authenticate_admin！在我的控制器中，但是当我测试出来时，页面仍然是可访问的，并且允许任何人签出管理选项。我有有限的选择，管理员一旦签署。问题是任何人都可以登记。如果我基本上可以阻止访问管理注册页面，那么我是黄金。至少在这种情况下。我很好奇是否有人能指出我的错误或错误。如果你还需要什么就告诉我。谢谢

class AdminsController < ApplicationController
  before_action :authenticate_admin!



  def index
  end

  def created
  end
end

物品控制器

class ArticlesController < ApplicationController
  before_action :authenticate_admin!, :except => [:index, :show]




  def new
    @article = Article.new
  end

  def index
    @article = Article.all


    @articles = Article.order('created_at DESC')
    @articles_by_month = Article.find(:all, :order => 'created_at DESC').group_by { |article| article.created_at.strftime("%B %Y") }
  end


  def month_count
    @articles_by_month = Article.find(:all, :order => 'created_at DESC').group_by { |article| article.created_at.strftime("%B %Y") }
  end

  def create  
    @article = Article.new(article_params)

      if @article.save
      redirect_to @article
    else
      render 'new'
    end
  end



  def edit
    @article = Article.find(params[:id])
  end

  def update
    @article = Article.find(params[:id])

    if @article.update(article_params)
      redirect_to @article
    else
      render 'edit'
    end
  end


  def show
    @article = Article.find(params[:id])
  end

  def destroy
    @article = Article.find(params[:id])
    @article.destroy

    redirect_to articles_path
  end

  private

  def article_params
    params.require(:article).permit(:title, :text, :image)
  end

end

文章索引视图

管理模型

class Admin < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable
end

文章模型

class Article < ActiveRecord::Base
  has_many :comments, dependent: :destroy
  validates :title, presence: true,
                    length: { minimum: 5 }
  mount_uploader :image, ImageUploader 
  default_scope -> { order('created_at DESC') }                 
end

路线

Blog::Application.routes.draw do
  devise_for :admins

  devise_scope :admin do get "/admins/sign_out", to: 'devise/sessions#destroy'
  end

  devise_scope :admin do
    get "/admins/sign_in", to: "devise/sessions#new"
  end

  devise_for :users
  root 'articles#index'

  resources :articles do
    resources :comments
  end


  get "welcome/index"



  match '/about',     to: 'static_pages#about',     via: 'get'
  match '/contact',   to: 'static_pages#contact',   via: 'get'
  match '/archives',  to: 'archives#index',         via: 'get'

Answer 1

您可以在您的管理模型中删除registerable，以防止人们以管理员身份注册：

devise :database_authenticatable, :recoverable, :rememberable, :trackable, :validatable

但是，让devise_for :admins和:users提示您现在应该考虑使用权限管理gem，比如CanCanCan。
