[英]cancan ability : allow site admin with rolify role create_user to create or sign_up new devise users
對於該應用程序,我正在嘗試使用cancan / cancancan來實現job_code樣式訪問,並進行設計和發布。
只有具有job_code:create_user的站點管理員才能創建新用戶
以下是代碼:
class RegistrationsController < Devise::RegistrationsController
before_filter :check_permissions, :only => [ :new, :create, :cancel ]
skip_before_filter :require_no_authentication
def check_permissions
authorize! :create, resource
end
end
class Ability
include CanCan::Ability
def initialize(user)
alias_action :create, :read, :update, :destroy, :to => :crud
if user.has_role? :create_user
can :create, User
end
if user.has_role? :create_annoucement
can :create, Announcement
end
end
end
在routes.rb中,我有
devise_for :users ,:controllers => { :registrations => "registrations" }, :path_names => {:sign_in => "login", :sign_out => "logout"}, :path => "account"
應用控制器
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
before_action :authenticate_user!
check_authorization unless: :devise_controller?
before_filter :set_start_time if Rails.env.development?
before_action :configure_permitted_parameters, if: :devise_controller?
rescue_from CanCan::AccessDenied do |exception|
#https://github.com/ryanb/cancan/wiki/Devise
if current_user.nil?
session[:next] = request.fullpath
puts session[:next]
redirect_to new_user_session_path, :alert => "You have to log in to continue."
else
render file: "#{Rails.root}/public/403", formats: [:html], status: 403, layout: false
end
end
def set_start_time
@start_time = Time.now.usec
end
def configure_permitted_parameters
#devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:name, :email) }
devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:first_name, :last_name, :email, :password, :password_confirmation) }
devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:first_name, :last_name, :email, :password, :password_confirmation, :current_password, :user_manual) }
end
end
當我使用時,abilities.rb中的以下代碼
if user.has_role? :create_user
can :create, :all
end
它工作完美 。 我需要進入“用戶注冊”頁面
但是,當我有這段代碼時
if user.has_role? :create_user
can :create, User
end
它說拒絕訪問(403頁)
我有一個很難弄清楚,我應該怎么用的,而不是用戶 can :create, User
我必須添加:read
以及:create
權限來訪問新的/創建操作,然后解析:read
訪問
