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>`

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.
