Rails路由到新的关联模型

我有一个应用程序，有家庭访问我的机构，我每次访问家庭时都会记录。 我在家庭索引中选择家庭并打开我的索引中访问模型中的访问视图以选择家庭并创建新访问我在家庭的索引视图中使用以下代码：

= link_to 'Visit', new_household_visit_path(household), class: 'btn btn-mini' 

Rake Routes节目：

 new_household_visit GET /households/:household_id/visits/new(.:format) visits#new 

这会将我带到包含以下url的表单：

  http://localhost:3000/households/5/visits/new 

我在此视图中设置了一个简单的表单，如下所示：

 = simple_form_for [household, visit], url: new_household_visit_path do |f| %h2 Household: #{household.name} 

现在，当我填写表单并尝试使用提交保存时，我得到：

  No route matches [POST] "/households/5/visits/new" 

现在我注意到在Rake Routes中我有一个GET而不是POST但是我仍然不确定我的问题是什么？

Routes.rb显示：

  resources :households do resources :visits resources :neighbors end 

我将简单的表单调用改为：

 = simple_form_for [household, visit], url: household_visits_path do |f| 

我正在创建我的表单，但在保存时我得到错误：

 Required parameter missing: household 

日志显示：

我相信我越来越近了

假设您正在使用标准路线，例如：

 resources :households do resources :visits end 

然后你想发布到household_visits_path而不是new_household_visit_path 。

如果你运行rake routes你可能会得到类似的东西：

  household_visits GET /households/:household_id/visits(.:format) visits#index POST /households/:household_id/visits(.:format) visits#create new_household_visit GET /households/:household_id/visits/new(.:format) visits#new edit_household_visit GET /households/:household_id/visits/:id/edit(.:format) visits#edit household_visit GET /households/:household_id/visits/:id(.:format) visits#show PUT /households/:household_id/visits/:id(.:format) visits#update DELETE /households/:household_id/visits/:id(.:format) visits#destroy 

你会发现接受POST请求的唯一一个是household_visits 。 new_household_visit仅用于获取表单。
