我的路线看起来像这样
的routes.rb
get '/:pimp_id/mepagers(.:format)', :to => 'mepagers#index', :as => 'mepagers'
get '/:pimp_id/mepager/new(.:format)', :to => 'mepagers#new', :as => 'new_mepager'
get '/:pimp_id/mepager/edit(.:format)', :to => 'mepagers#edit', :as => 'edit_mepager'
get '/:pimp_id/mepager(.:format)', :to => 'mepagers#show', :as => 'mepager'
post '/:pimp_id/mepager(.:format)', :to => 'mepagers#create', :as => 'create_mepager'
put '/:pimp_id/mepager(.:format)', :to => 'mepagers#update'
patch '/:pimp_id/mepager(.:format)', :to => 'mepagers#update'
delete '/:pimp_id/mepager(.:format)', :to => 'mepagers#destroy'
我试图从
中获取表格HTTP Verb Path Controller#Action Used for
GET /geocoder/new geocoders#new return an HTML form for creating the geocoder
POST /geocoder geocoders#create create the new geocoder
GET /geocoder geocoders#show display the one and only geocoder resource

PATCH/PUT /geocoder geocoders#update update the one and only geocoder resource

（来源http://guides.rubyonrails.org/routing.html）
但是当我点击/ 1 / mepager / new上的提交按钮时，我收到以下错误：
Routing Error
No route matches [POST] "/1/mepager/new"
我甚至试图将后期行动路线更改为/ 1 / mepager / new，但这根本没有帮助，因为他无法找到mepager的参数。 Coudlnt在谷歌上发现任何类似的东西，所以我希望有人可以帮助这个路由让我生病！

答案 0 :(得分：0)
请参阅form_for here
参考与上述有关的文件; form_for方法需要一些参数：
在您的情况下，我认为您要做的是将'mepager_path'命名路径作为应提交表单的URL。但是，您错过了form_for参数的分隔符，因此Rails认为'mepager_path'是record参数的值。
record参数用于传达有关表单应描述的对象的信息，以便Rails可以推断对象的属性，从而为您创建表单，而开发人员的开销最小。在你的情况下，我认为你可以尝试像
<%= form_for :mepager, url: mepager_path do |f| %>
我也是一个Rails noob，所以我不能保证我的代码示例是正确的，但我的答案的要点是你的form_for参数不正确。作为Rails的新手，我不断受到不同形式参数的挫败感。对我来说，多种形式使它们难以阅读，我不断地确保我不会误解代码。此外，哈希语法总是让我困惑。
我的回答来自here。我发现它是一个非常有用的参考站点。
希望我的回答可以帮到你。
