Rails 三 的删除方法不能用了 delete put

Rails 3 的删除方法不能用了 delete put
update:
先试试

#production.rbconfig.serve_static_assets = true

有view

<%= link_to "Delete", admin_question_path(question), :confirm => "Are you sure?", :method=>:delete %>

#生成如下<a href="/admin/questions/3" data-method="delete" rel="nofollow">Delete</a>

http://localhost:3000/admin/questions/4/edit#而不是http://localhost:3000/admin/questions/4/destroy

#routes.rbQuestionator::Application.routes.draw do |map|  root :to => "admin/dashboard#show"    namespace "admin" do    root :to => "admin/dashboard#show"    resources :questions  endendrake routesadmin_question DELETE /admin/questions/:id(.:format)      {:action=>"destroy", :controller=>"admin/questions"}

所以不是路由的问题，

然后，看到说换button_to 因为Rails 3用的javascript转换的rest对应的方法，如果，你的javascript加载和jquery加载冲突就会有问题

<%= csrf_meta_tag %><%= javascript_include_tag :defaults %><%= javascript_include_tag 'jquery-1.4.2.min','jquery.form','rails.js'%>

 <%= button_to "Delete", admin_question_path(@question.id), :method=>:delete, :class=>:destroy,:confirm=>"Are you sure?" %><form method="post" action="/admin/questions/244"  type="hidden" value="delete" />    <input data-confirm="Are you sure?" type="submit" value="Delete" />    <input name="authenticity_token" type="hidden" value="yApLSCAIIqDBeubxR7RflOo+BnDByQHgSJzhtKvIATM=" />  </div></form>
