Rails路由命名空间和form_for
我有我的routes.rb命名空间
namespace :businesses do resources :registration end 我的控制器在一个子目录business / registration_controller。
def new @business = Business.new end
在我看来，我想做这个form_for @business do |f| ... form_for @business do |f| ...但我收到以下错误：
No route matches {:controller=>"businesses", :action=>"create"}
重新启动服务器，我也得到这个：
undefined method business_path'for＃<＃：0x10339bb20>`
这里是我的耙路线：
home_index GET /home/index(.:format) {:action=>"index", :controller=>"home"} new_user_session GET /users/sign_in(.:format) {:action=>"new", :controller=>"devise/sessions"} user_session POST /users/sign_in(.:format) {:action=>"create", :controller=>"devise/sessions"} destroy_user_session GET /users/sign_out(.:format) {:action=>"destroy", :controller=>"devise/sessions"} user_password POST /users/password(.:format) {:action=>"create", :controller=>"devise/passwords"} new_user_password GET /users/password/new(.:format) {:action=>"new", :controller=>"devise/passwords"} edit_user_password GET /users/password/edit(.:format) {:action=>"edit", :controller=>"devise/passwords"} user_password PUT /users/password(.:format) {:action=>"update", :controller=>"devise/passwords"} cancel_user_registration GET /users/cancel(.:format) {:action=>"cancel", :controller=>"devise/registrations"} user_registration POST /users(.:format) {:action=>"create", :controller=>"devise/registrations"} new_user_registration GET /users/sign_up(.:format) {:action=>"new", :controller=>"devise/registrations"} edit_user_registration GET /users/edit(.:format) {:action=>"edit", :controller=>"devise/registrations"} user_registration PUT /users(.:format) {:action=>"update", :controller=>"devise/registrations"} user_registration DELETE /users(.:format) {:action=>"destroy", :controller=>"devise/registrations"} users GET /users(.:format) {:action=>"index", :controller=>"users"} users POST /users(.:format) {:action=>"create", :controller=>"users"} new_user GET /users/new(.:format) {:action=>"new", :controller=>"users"} edit_user GET /users/:id/edit(.:format) {:action=>"edit", :controller=>"users"} user GET /users/:id(.:format) {:action=>"show", :controller=>"users"} user PUT /users/:id(.:format) {:action=>"update", :controller=>"users"} user DELETE /users/:id(.:format) {:action=>"destroy", :controller=>"users"} full_tree_admin_categories GET /admin/categories/full_tree(.:format) {:action=>"full_tree", :controller=>"admin/categories"} admin_categories GET /admin/categories(.:format) {:action=>"index", :controller=>"admin/categories"} admin_categories POST /admin/categories(.:format) {:action=>"create", :controller=>"admin/categories"} new_admin_category GET /admin/categories/new(.:format) {:action=>"new", :controller=>"admin/categories"} edit_admin_category GET /admin/categories/:id/edit(.:format) {:action=>"edit", :controller=>"admin/categories"} admin_category GET /admin/categories/:id(.:format) {:action=>"show", :controller=>"admin/categories"} admin_category PUT /admin/categories/:id(.:format) {:action=>"update", :controller=>"admin/categories"} admin_category DELETE /admin/categories/:id(.:format) {:action=>"destroy", :controller=>"admin/categories"} businesses_registration_index GET /businesses/registration(.:format) {:action=>"index", :controller=>"businesses/registration"} businesses_registration_index POST /businesses/registration(.:format) {:action=>"create", :controller=>"businesses/registration"} new_businesses_registration GET /businesses/registration/new(.:format) {:action=>"new", :controller=>"businesses/registration"} edit_businesses_registration GET /businesses/registration/:id/edit(.:format) {:action=>"edit", :controller=>"businesses/registration"} businesses_registration GET /businesses/registration/:id(.:format) {:action=>"show", :controller=>"businesses/registration"} businesses_registration PUT /businesses/registration/:id(.:format) {:action=>"update", :controller=>"businesses/registration"} businesses_registration DELETE /businesses/registration/:id(.:format) {:action=>"destroy", :controller=>"businesses/registration"} root /(.:format) {:action=>"index", :controller=>"home"}
如果你有命名空间的路线，最好的方法是：
class Admin::BusinessesController < ApplicationController def new @business = Business.new end end
在routes.rb中：
namespace :admin do resources :businesses end
鉴于：
form_for [:admin, @business] do |f|...
文档： http : //guides.rubyonrails.org/form_helpers.html第2.3.1节处理命名空间
关于你的情况：
在routes.rb中，一切都是o'k。 在视图中，您应该明确地写入url，因为在控制器名称以外的其他控制器中有variables：
form_for @business, :url => business_registration_path do |f|...
我想在企业/ registration_controller你有这样的事情：
class Businesses::RegistrationController < ApplicationController def new @business = Business.new end end
还有一点意见：我不会创buildregistration_controller注册一个新的业务。 我认为在business_controller中保持业务相关的行为要清楚得多。
其实我觉得有一个更好的解决办法
form_for [:admin, @business]
给url的问题是，如果您将表单抽象为局部视图，则需要处理“创build”和“更新”情况。 他们指向不同的URL，最后在控制器中提供@url 。
