Rails 4设计强大的参数管理模型 [英] Rails 4 Devise Strong Parameters Admin Model

问题描述

我已经使用设计制作了一个用户和管理模型。我在 app / controllers / application_controller.rb 文件中使用了很强的参数。

  class ApplicationController< ActionController :: Base 
＃通过引发异常来防止CSRF攻击。 
＃对于API，您可能需要使用：null_session。 
 protect_from_forgery with：：exception 
 before_filter：configure_permitted_pa​​rameters，如果：：devise_controller？ 
 
 protected 
 
 def configure_permitted_pa​​rameters 
 devise_parameter_sanitizer.for（：sign_up）{| u | u.permit（：username，：email，：password，：password_confirmation，：remember_me）} 
 devise_parameter_sanitizer.for（：sign_in）{| u | u.permit（：login，：password，：remember_me）} 
 end 
 
 end 
  

如何将管理模型列入白名单？

  devise_parameter_sanitizer.for（：sign_in）{| a | a.permit（：login，：password，，remember_me）} 
  

另外如何将管理员列入白名单sign_up，以便没有变量可以传递给它？我的猜测是

  devise_parameter_sanitizer.for（：sign_up）{| a | a.permit（）} 
  

更新

我想编辑我的问题。

我的问题是如何让管理员模型自动黑名单我的管理员注册页面？如果我完全没有留下任何内容，那么我仍然可以通过admins / sign_up注册。当然可以删除app / models / admin.rb中的注册，但是我想拒绝命令行注册

- 使用范围视图并明确定义管理员和用户模型的每个视图是否明智？ -

解决方案

如果您有用户和管理员的单独控制器，请尝试以下操作：

  def configure_permitted_pa​​rameters 
如果params [：controller ] ==user
 devise_parameter_sanitizer.for（：sign_up）{| u | u.permit（：username，：email，：password，：password_confirmation，：remember_me）} 
 devise_parameter_sanitizer.for（：sign_in）{| u | u.permit（：login，：password，，remember_me）} 
 else 
 devise_parameter_sanitizer.for（：sign_in）{| a | a.permit（：login，：password，：remember_me）} 
 devise_parameter_sanitizer.for（：sign_up）{| a | a.permit（）} 
  

并且还有另一种方法，只为两者创建一个控制器用户和管理员（命名为registrations_controller.rb）在您的用户表中有一个名为is_admin的字段，只有当他/她是管理员时才将其设置为用户。创建一个种子，使您的seed.rb文件中的管理员如下所示：

  admin_user = User.new（email：abc @ xyz.com，密码：123，password_confirmation：123，is_admin：true）
 admin_user.skip_confirmation！ 
 admin_user.save 
  

I have made a user and admin model using devise. I have used strong parameters in the app/controllers/application_controller.rb file

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_filter :configure_permitted_parameters, if: :devise_controller?

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username, :email, :password, :password_confirmation, :remember_me) }
    devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:login, :password, :remember_me) }
  end

end

How do I whitelist the admin model?

devise_parameter_sanitizer.for(:sign_in) { |a| a.permit(:login, :password, :remember_me) }

Also how do I whitelist the admin sign_up so that no variables may be passed into it? My guess is

devise_parameter_sanitizer.for(:sign_up) { |a| a.permit()}

UPDATE

I would like to edit my question.

My question is how do I get the admin model to automatically blacklist my admin sign up page? If I simply leave nothing then I can still sign up through the "admins/sign_up". Sure I can delete the :regisitrations within the "app/models/admin.rb", but I would like to deny command line sign ups

--Would it be wise to use scoped views and specifically define each view for the admin and user models?--

解决方案

If you have separate controllers for users and admins then try something like this:

def configure_permitted_parameters
  if params[:controller] == "user"
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username, :email, :password, :password_confirmation, :remember_me) }
    devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:login, :password, :remember_me) }
  else
    devise_parameter_sanitizer.for(:sign_in) { |a| a.permit(:login, :password, :remember_me) }
    devise_parameter_sanitizer.for(:sign_up) { |a| a.permit()}

and there's another approach to it as well, create only one controller for both users and admin, named registrations_controller.rb, have a field in your users table named is_admin and set it for a user only if he/she is a admin. Create a seed to make your admins like this in your seeds.rb file:

admin_user = User.new(email: "[e-mail]", password: "123", password_confirmation: "123", is_admin: "true" )
admin_user.skip_confirmation!
admin_user.save
