自定义路由与奇异的资源错误

Question

我的路线是这样看

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' 

我试图采取的形式从

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 
GET /geocoder/edit geocoders#edit return an HTML form for editing the geocoder 
PATCH/PUT /geocoder geocoders#update update the one and only geocoder resource 
DELETE /geocoder geocoders#destroy delete the 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，出现以下错误：

Routing Error 
No route matches [POST] "/1/mepager/new" 

我甚至试过后的行动路线更改为/ 1/mepager /新但这​​没有帮助，因为在所有他不能找到mepager帕拉姆然后。 Coudlnt在谷歌上找到类似的东西，所以我希望有人能帮助这个路由让我恶心！

Answer 1

参见上form_forhere

参照上方连结的文档文件;该form_for方法需要几个参数：

1. 记录
2. 选项
3. 块

在你的情况，我认为你想做什么是经过'mepager_path'命名路径的URL该表格应该提交。但是，您缺少form_for参数的分隔符，因此Rails认为'mepager_path'是record参数的值。

record参数是为了传达关于表单应该描述的对象的信息，以便Rails能够以最小的开销为开发人员推断对象的属性，从而为您创建表单。在你的情况，我想你可以尝试像

<%= form_for :mepager, url: mepager_path do |f| %> 

我也是一个Rails小白成才，所以我不能答应你，我的代码示例是正确的，但我的答案的要点是，你form_for参数不正确。作为Rails的新手，我经常因参数不同而感到沮丧。对我来说，众多的表格使他们难以阅读，而且我经常必须确保我不会误解代码。另外，哈希语法总是让我困惑。

我的答案取自here。我发现它是一个非常有用的参考网站。

希望我的回答能帮助你。
