Question

我有一个叫做员工的控制器。

class EmployeesController < ApplicationController

  def admission    
    @bank_fields = BankField.all.where(:status => true)
    if @bank_fields.empty?
      redirect_to  :action => "show", :id => @bank_fields.first.id
    end    
  end

  def show
    @employee = Employee.find(params[:id])
  end

  # The RESTful actions are as usual; I didn't give those here.
end

在路线文件

中

match ':controller/:action/:id', :via => [:get, :post,:put]

match ':controller/:action', :via => [:post, :get]

resources :employees

在视图中，我通过

调用了该录取行动

 <%= link_to 'admission', :controller => :employees, :action => :admission %>

但是当我按下链接时出现以下错误。

ActiveRecord::RecordNotFound at /employees/admisson
 Couldn't find Employee with id=admisson

这意味着它对节目动作的影响。我不知道为什么。有什么解决方案。谢谢

Answer 1

您的route.rb文件中的路由有点奇怪。只需使用指定自定义操作的通用方法，方法是将其添加到资源块：

resources :employees do
  collection do
    get :admission
  end
end

Answer 2

根据评论，如果您想重定向到match ':controller/:action', :via => [:post, :get]，只需按照以下方式修改路线。

match ':controller/:action', :via => [:post, :get] #primary

match ':controller/:action/:id', :via => [:get, :post,:put] #secondary

之前

match ':controller/:action/:id', :via => [:get, :post,:put] #primary

match ':controller/:action', :via => [:post, :get] #secondary

因此，主要路线需要:id，并且您未在:id中传递link_to。错误也是如此。

你的问题是你没有使用Rails'resourceful routing structure（这是Rails如何计算路由的基础）：

#config/routes.rb
resources :employees
   #-> get /employees, to: "employees#index"
   #-> get /employees/:id, to: "employees#show", id: :id
   #-> get /employees/new, to: "employees#new"
   #-> post /employees/new, to: "employees#create"
   #-> get /employees/:id/edit, to: "employees#edit"
   #-> patch /employees/:id, to: "employees#update"
   #-> delete /employees/:id, to: "employees#destroy"

您可以使用collection方法为您提供“集体”路线（存储集合的数据）或member路线（其中单< / em>处理数据记录）：

#config/routes.rb resources :employees do get :admission, as: :collection end

这与您对Rails path helpers的禁欲相结合，这将有助于您相应地路由您的请求：

<%= link_to 'admission', employees_admission_path %>
