Rails 3.0.10，客户路线，post和form_for标签 [英] Rails 3.0.10, customer routes, post and form_for tag

问题描述

我的路线上有这个

resources :events do
  collection do
    post 'moderate'
  end
end

耙道告诉我：

moderate_events POST /events/moderate(.:format) {:controller=>"events", :action=>"moderate"}

我有一个管理控制器，仅列出了需要审核的事件：

I have an "administration" controller that simply lists Events that need moderating:

@modevents = Event.where('moderated <> 1')

到目前为止，所有尚未审核的事件都可以显示在视图中：

So far so good, all the events that haven't been moderated can be displayed in the view:

<%- @modevents.each do |me| -%>
  Display Stuff here
<%- end -%>

我想在循环中添加一个表单来更新已调整的值，但是为了我的生命，我无法计算出要放在form_for中的内容-我已经尝试过：

I want to put a form in the loop that updated the moderated value but for the life of me I can't work out what to put in the form_for - I have tried:

<%= form_for me, :url => moderate_events_path do |f| %>
  <%= f.submit %>
<% end %>

返回的html是：

<form accept-charset="UTF-8" action="/events/moderate" class="edit_event" id="edit_event_1" method="post">
  <div style="margin:0;padding:0;display:inline">
  <input name="utf8" type="hidden" value="&#x2713;" />
  <input name="_method" type="hidden" value="put" />

当我单击提交按钮时，出现以下错误：

When I click the "Submit" button I get the following error:

Couldn't find Event with ID=moderate

解决方案非常简单，在路由中将 post更改为 put：

The solution is very simple, in routes change "post" to "put":

resources :events do
  collection do
    put 'moderate'
  end
end

现在它可以正常工作了。更新，甚至是自定义更新也是 put函数。

And now it works as it should. Updates, even custom ones are "put" functions.

推荐答案

您还可以通过指定以下内容来使用POST：

You can also use POST by specifying:

<%= form_for me, :url => moderate_events_path, :method => :post do |f| %>

但是如前所述，需要在更新和创建之间进行区分。 Rails中的标准是update == put和create == post。

but as said before, the distinction needs to be made between updating and creating. The standard in rails is update==put, and create==post.
