Rails，Devise：相同的资源，基于用户类型的不同的控制器 [英] Rails, Devise: Same resource, different controller based on user type

问题描述

我有一个资源，说产品，可以由两个不同的用户类访问：说客户和管理。这两个之间没有遗产。

I have a resource, say Product, which can be accessed by two different user classes: say Customer and Admin. There is no inheritance between these two.

我正在使用Devise进行身份验证：

I am using Devise for authentication:

# config/routes.rb

devises_for :customers
deviser_for :admins

我有这两个控制器：

# app/controllers/customers/products_controller.rb

class Customers::ProductsController < ApplicationController

和

# app/controllers/admins/products_controller.rb

class Admins::ProductsController < ApplicationController

现在取决于谁登录（客户或 Admin ），我想要 products_path 指向相应的控制器。而且我想避免使用 customers_products_path 和 admins_products_path ，这很麻烦。

Now depending on who logs in (Customer or Admin), I want products_path to point to the corresponding controller. And I want to avoid having customers_products_path and admins_products_path, that's messy.

所以我设置了我的路线这样

So I have setup my routes as such

# config/routes.rb

devise_scope :admin do
  resources :products, module: 'admins'
end

devise_scope :customer do
  resources :products, module: 'customers'
end

这不行。当我以客户登录时， products_path 仍然指向 Admins :: ProductsController＃index 因为它是第一个定义。

This doesn't work. When I login as a Customer, products_path still points to Admins::ProductsController#index as it is the first defined.

任何线索？

更新
根据代码，这是不可行的。

推荐答案

事实证明，使用路由约束的最佳方式是：

It turns out the best way to achieve that is to use routing constraints as such:

# config/routes.rb

resources :products, module: 'customers', constraints: CustomersConstraint.new
resources :products, module: 'admins', constraints: AdminsConstraint.new


# app/helpers/customers_constraint.rb

class CustomersConstraint
  def matches? request
    !!request.env["warden"].user(:customer)
  end
end


# app/helpers/admins_constraint.rb

class AdminsConstraint
  def matches? request
    !!request.env["warden"].user(:admin)
  end
end

我将约束对象存储在帮助文件夹中，因为我真的不知道放置它们的最佳位置。

I stored the constraint objects in the helper folder because I don't really know the best place to put them.
