Ruby on rails rails的路由错误-未初始化的常量控制器

ruby-on-rails ruby routing

Ruby on rails rails的路由错误-未初始化的常量控制器,ruby-on-rails,ruby,routing,Ruby On Rails,Ruby,Routing,我有一个订户模型，它接受一个“电话号码”和一个“访问”整数。我有两个控制器订阅者和访问（super和sub）。我以前从未使用过嵌套控制器，我认为我的命名空间有一些问题。因为我得到了未初始化的常量错误。基本上，订户控制器注册订户，访问控制器通过用户输入他们的电话号码统计他们访问的次数。为什么我会犯这个错误？为了清晰起见，我将显示我的代码 控制器 class Subscribers::VisitsController < ApplicationController def new

我有一个
订户
模型，它接受一个“电话号码”和一个“访问”整数。我有两个控制器
订阅者
和
访问
（super和sub）。我以前从未使用过嵌套控制器，我认为我的命名空间有一些问题。因为我得到了未初始化的常量错误。基本上，订户控制器注册订户，访问控制器通过用户输入他们的电话号码统计他们访问的次数。为什么我会犯这个错误？为了清晰起见，我将显示我的代码

控制器

  class Subscribers::VisitsController < ApplicationController
   def new
    @subscriber = Subscriber.new
   end

   def create
    @subscriber = Subscriber.find_by_phone_number(params[:phone_number])
    if @subscriber
     @subscriber.visit += 1
     @subscriber.save
     redirect_to subscribers_visits_new_path(:subscriber)

嘿
错误

您可能不需要从一个控制器继承另一个控制器。只需按照通常的方式定义控制器：

app/controllers/subscribers\u controller.rb

class SubscribersController < ApplicationController
  # methods for Subscribers
end

class VisitsController < ApplicationController
  # methods for Visits
end
这将产生以下路线：

GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
GET    /subscribers/:id/visits/new
POST   /subscribers/:id/visits
GET    /subscribers/:id/visits
GET    /subscribers/:id/visits/:id
GET    /subscribers/:id/visits/:id/edit
PATCH  /subscribers/:id/visits/:id/update
DELETE /subscribers/:id/visits/:id/destroy

GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
GET    /subscribers/visits/new
POST   /subscribers/visits

GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
GET    /subscribers/:id/visits/new
POST   /subscribers/:id/visits

GET    /subscribers/visits/new
POST   /subscribers/visits
GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
这是嵌套资源和独立控制器的典型路由结构

2）要在VisitController中进行
访问#新建
一个简单的集合（非成员）操作，您可能需要：

resources :subscribers, except: :show do
  collection do
    get 'visits/new', to 'visits#new'
    post 'visits', to 'visits#create'
  end
end
这将产生以下路线：

GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
GET    /subscribers/:id/visits/new
POST   /subscribers/:id/visits
GET    /subscribers/:id/visits
GET    /subscribers/:id/visits/:id
GET    /subscribers/:id/visits/:id/edit
PATCH  /subscribers/:id/visits/:id/update
DELETE /subscribers/:id/visits/:id/destroy

GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
GET    /subscribers/visits/new
POST   /subscribers/visits

GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
GET    /subscribers/:id/visits/new
POST   /subscribers/:id/visits

GET    /subscribers/visits/new
POST   /subscribers/visits
GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
这通常用于在现有资源和控制器中添加新的顶级路由

3）要将
访问构建为成员操作，请使用以下命令：


resources :subscribers, except: :show do
  resources :visits
end



resources :subscribers, except: :show do
  member do
    get 'visits/new', to 'visits#new'
    post 'visits', to 'visits#create'
  end
end



get '/subscribers/visits/new', to: 'visits#new'
post '/subscribers/visits', to: 'visits#create'
resources :subscribers, except: :show


这将产生以下路线：


GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
GET    /subscribers/:id/visits/new
POST   /subscribers/:id/visits
GET    /subscribers/:id/visits
GET    /subscribers/:id/visits/:id
GET    /subscribers/:id/visits/:id/edit
PATCH  /subscribers/:id/visits/:id/update
DELETE /subscribers/:id/visits/:id/destroy



GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
GET    /subscribers/visits/new
POST   /subscribers/visits



GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
GET    /subscribers/:id/visits/new
POST   /subscribers/:id/visits



GET    /subscribers/visits/new
POST   /subscribers/visits
GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy


这通常用于在现有资源和控制器中添加新成员路由

4）要简单地使
访问
路线显示为包含在
订户
中，您可以使用以下方法：


resources :subscribers, except: :show do
  resources :visits
end



resources :subscribers, except: :show do
  member do
    get 'visits/new', to 'visits#new'
    post 'visits', to 'visits#create'
  end
end



get '/subscribers/visits/new', to: 'visits#new'
post '/subscribers/visits', to: 'visits#create'
resources :subscribers, except: :show


这将产生以下路线：


GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
GET    /subscribers/:id/visits/new
POST   /subscribers/:id/visits
GET    /subscribers/:id/visits
GET    /subscribers/:id/visits/:id
GET    /subscribers/:id/visits/:id/edit
PATCH  /subscribers/:id/visits/:id/update
DELETE /subscribers/:id/visits/:id/destroy



GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
GET    /subscribers/visits/new
POST   /subscribers/visits



GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy
GET    /subscribers/:id/visits/new
POST   /subscribers/:id/visits



GET    /subscribers/visits/new
POST   /subscribers/visits
GET    /subscribers/new
POST   /subscribers
GET    /subscribers
GET    /subscribers/:id/edit
PATCH  /subscribers/:id/update
DELETE /subscribers/:id/destroy



这可能用于使任意路由看起来包含在现有资源中，而实际上它们可能是独立的。
Hmm，我猜您正在尝试将url
订户/访问/new
路由到
visitscoller
中的
新建
操作。更改此行如何：


get '/subscribers/visits/new', to: 'subscribers/visits#new'


致：

如果仍然出现错误，请尝试将此块移到
resources:subscribers上方，但：：show
除外


干杯
您能为这两个控制器粘贴
路线.rb
吗？为您设置了这些路线访问控制器的目的是什么？你不能在订阅者控制器中执行一个访问操作，然后有一个到订阅者的路径#访问
并更新那里的访问字段吗？请提供完整日志，包括错误的回溯。您可以在Rails控制台或
log/development.log
中找到失败的操作。将所有内容从操作的
开始
行复制到
完成
行（或日志末尾）非常重要。仍然会收到错误。谢谢你的帮助though@CameronBass我更新了答案，并为您可能使用的不同路线添加了一些选项和说明。在重新阅读您的问题时，您真正的意思是想要嵌套的路由，而不是嵌套的控制器，所以这个答案包括如何做到这一点。
