ruby-on-rails - 了解铁路路线

Question

我对 Rails 路由的工作原理感到非常困惑。此时我有一个非常简单的应用程序，因此应该很容易调试。这是我的问题 - 我有一个 Controller 试图调用一个显示 Action ，但它似乎覆盖了我在同一个 Controller 中调用的另一个 Action 。据我所知，rake routes 是，如果 url 读取此 localhost.com/subscribers/1 应该呈现我想查看的订阅者的 id，但我也有一个像这样调用的 url localhost.com/subscribers/visit 这么有效，这些页面现在都不起作用了吗？我真的不知道这里发生了什么，所以任何帮助都会很棒!这是我的代码。

Controller

   class SubscribersController < ApplicationController
  helper_method :sort_column, :sort_direction

  def index
    @search = Subscriber.search(params[:q])
    @subscriber = @search.result
    @search.build_condition if @search.conditions.empty?
    @search.build_sort if @search.sorts.empty?
  end

  def show
    @subscriber = Subscriber.find_by(id: params[:id])
  end

  def new
    @subscriber = Subscriber.new
  end

  def create
    @subscriber = Subscriber.new(subscriber_params)
    if @subscriber.save
      @subscriber.touch(:subscription_date)
      SubscriberMailer.welcome_subscriber(@subscriber).deliver_now
      flash[:notice] = "Subscriber Has Been Successfully Created"
      redirect_to new_subscriber_path(:subscriber)
    else
      render "new"
    end
  end

  def search
    @subscriber = Subscriber.new
  end

  def visit
    @subscriber = Subscriber.find_by_phone_number(params[:phone_number])
    if @subscriber
      @subscriber.visit ||= 0
      @subscriber.visit += 1
      @subscriber.save
      render "visit"
    end
  end

路线:

    devise_for :users
  resources :subscribers 
  resources :comments, only: [:new, :create]

  get "subscribers/search", to: "subscribers#search"
  get "subscribers/visit", to: "subscribers#visit"

  root "subscribers#new"

RAKE 路线:

subscribers GET    /subscribers(.:format)             subscribers#index
                   POST   /subscribers(.:format)             subscribers#create

    new_subscriber GET    /subscribers/new(.:format)         subscribers#new
   edit_subscriber GET    /subscribers/:id/edit(.:format)    subscribers#edit
        subscriber GET    /subscribers/:id(.:format)         subscribers#show
                   PATCH  /subscribers/:id(.:format)         subscribers#update
                   PUT    /subscribers/:id(.:format)         subscribers#update
                   DELETE /subscribers/:id(.:format)         subscribers#destroy
          comments POST   /comments(.:format)                comments#create
       new_comment GET    /comments/new(.:format)            comments#new
subscribers_search GET    /subscribers/search(.:format)      subscribers#search
 subscribers_visit GET    /subscribers/visit(.:format)       subscribers#visit

我在这里做错了什么吗？请帮帮我!

路由器尝试匹配从 routes.rb 顶部到底部的路由，并使用第一个匹配的路由。

在您的情况下，/subscribers/visit 匹配 /subscribers/:id - 路由器认为这是 ID 为 visit< 的订阅者的显示操作.

如果您将自定义路径移动到路由文件中的 resources :subscribers 上方，您将实现预期的行为。
