Rails 路由命名空间和 form_for [英] Rails Routes Namespaces and form_for

问题描述

我的 routes.rb 中有命名空间

I have namespace in my routes.rb

  namespace :businesses do
    resources :registration
  end

我的控制器位于 business/registration_controller 子目录中.

My controller is in a subdirectory businesses/registration_controller.

def new
  @business = Business.new
end

在我看来，我想这样做 form_for @business do |f|... 但我收到以下错误:

In my view, I want to do this form_for @business do |f| ... but I am getting the following error:

没有路由匹配 {:controller=>"businesses", :action=>"create"}

重新启动服务器，我也得到这个:

Restarted the server and I'm also getting this:

未定义的方法businesses_path' for #<#:0x10339bb20>`

undefined methodbusinesses_path' for #<#:0x10339bb20>`

这是我的佣金路线:

推荐答案

如果你有命名空间路由，最好的方法是:

If you have namespaced routes the best way is:

class Admin::BusinessesController < ApplicationController
  def new
    @business = Business.new
  end
end

在 routes.rb 中:

in routes.rb:

namespace :admin do
  resources :businesses
end

在视图中:

form_for [:admin, @business] do |f|...

文档:http://guides.rubyonrails.org/form_helpers.html 部分 2.3.1 处理命名空间

The Docs: http://guides.rubyonrails.org/form_helpers.html section 2.3.1 Dealing with Namespaces

关于您的情况:

在 routes.rb 中一切正常.在视图中你应该明确写 url 因为你在控制器中有变量而不是控制器名称:

In routes.rb everything is o'k. In the view you should write url explicitly because you have variable in controller other than controller name:

form_for @business, :url => business_registration_path do |f|...

我想在 business/registration_controller 中你有这样的东西:

I suppose that in businesses/registration_controller you have something like this:

class Businesses::RegistrationController < ApplicationController
  def new
    @business = Business.new
  end
end

还有一句话:我不会创建 registration_controller 来注册新业务.我认为在 business_controller 中保留与业务相关的操作要清晰得多.

And one remark: I wouldn't create registration_controller for registering a new business. I think that keeping business related actions in business_controller is much clearer.
