Rails 资源路线中缺少新路线和编辑路线

Question

在构建 Rails API 时，我将路由文件声明为：

Rails.application.routes.draw do
  namespace :api do
    namespace :v1 do
      root 'budgets#index'
      resources :users do
        resources :budgets
      end
      post '/login', to: 'sessions#create'
      post '/logout', to: 'sessions#destroy'
      resources :budgets do
        resources :budget_totals
      end
    end
  end
end

但是，在运行rails routes 命令后，我发现缺少“新建”和“编辑”路由。我该如何纠正这个问题？

rails routes 响应的相关部分是：

您是否正在使用api_only 应用程序？那些不会生成 New 和 Edit 路由。

您是否使用--api 开关创建了您的应用程序，例如：rails new my-api --api？ --api 参数告诉 Rails 你只想要一个 API 应用程序。

参见“What Is Rails API?”和“Rails: Building a Ruby on Rails API-only app”。
