ruby-on-rails - 设计管理员重定向

Question

我使用 Devise + CanCan 并希望重定向到我的管理界面(由 rails admin gem 生成)如果它是 管理员 登录..

我定制了用户 使用以下命令重定向到他们各自的配置文件:

class ApplicationController < ActionController::Base
  protect_from_forgery
  rescue_from CanCan::AccessDenied do |exception|
    redirect_to root_path, :alert => exception.message
  end
  def after_sign_in_path_for(resource)
    user_path(current_user)
  end

end

角色.rb

class Role < ActiveRecord::Base
  has_and_belongs_to_many :users, :join_table => :users_roles
  belongs_to :resource, :polymorphic => true
end

能力.rb

class Ability
  include CanCan::Ability

  def initialize(user)
    user ||= User.new # guest user (not logged in)
    if user.has_role? :admin
      can :manage, :all
      can :access, :rails_admin
      can :dashboard 
    end

用户名

class User < ActiveRecord::Base
    rolify
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable
 .....

我假设你有一个 bool 值 admin您的 User 模型上的属性。

def after_sign_in_path_for(resource)
  if current_user.has_role? :admin
    rails_admin.dashboard_path
  else
    user_path(current_user)
  end
end
