Question

我正在尝试使用我的应用程序的bootstrap模式UI执行更新操作。但是，在更新表单中单击“提交”按钮后我获得的路径始终发送到event.3而不是事件/ 3。

我的rake路由显示PATCH操作定向到events /：id。我不确定为什么在单击表单中的提交按钮后，它会将/event.3 accoridng发送到日志。有人可以向我解释我做错了什么吗？

我的完整日历JS代码：

select: function(start,end){
    $.getScript('/event',function(){})

    calendar.fullCalendar('unselect')
},

eventClick: function(event){
    var url = 'events/' + event.id + '/edit';
    $.getScript(url,function(){});
    console.log(url);
}

途径：

resources :events, only:[:create, :index]
get '/event', to: 'events#new', as: '/event'
get 'events/:id/edit', to: 'events#edit'
patch 'events/:id', to: 'events#update'

RAKE ROUTES：

Prefix Verb   URI Pattern                Controller#Action              
events GET    /events(.:format)          events#index
       POST   /events(.:format)          events#create
 event GET    /event(.:format)           events#new
       GET    /events/:id/edit(.:format) events#edit
       PATCH  /events/:id(.:format)      events#update

CONTROLLER：

def edit
  @event = current_user.events.find(params[:id])   
end

def update    
  @event = current_user.events.find(params[:id])
  @event.update_attributes(event_params)   
end

问题

当你使用form_for（@event）时，最终计算网址的是polymorphic_url。正如您可以从“功能”部分中看到的那样：

form_for @event

在您的情况下，由于您使用的是event_url(@event)，这意味着您致电get '/event', to: 'events#new', as: '/event'

在你的路线中你有这个：

/event

因此，实际调用以计算网址表单的是event/:id而不是resources :events

如何修复

我建议您使用rails约定，然后使用get '/event', to: 'events#new', as: '/event'。但快速修复应该是这样的：

1）更新

get '/event', to: 'events#new', as: 'new_event'

到

patch 'events/:id', to: 'events#update'

2）更新

patch 'events/:id', to: 'events#update', as: 'event'

到

'events#new'

如果您这样做，请记住将旧的引用更新为{{1}}。

Answer 2

这一行...

<%= form_for @event, :remote => true do |f| %>

正在修补或投放到@event节目路径。

您可以更改路线以使编辑显式名称...

get 'events/:id/edit', to: 'events#edit', as: 'edit_event'

然后

<%= form_for edit_event_path(@event), :remote => true do |f| %>
