ruby-on-rails - rails 3 : Using Simple_form how do I create a form that do a Post to specialities#create?

Question

使用 Simple_form 如何创建一个表单来发布到专业#create？

我试过这个:

<%= simple_form_for @course_group, :html => 
   { :method => 'post', 
     :action=> 'create', 
     :controller=>'specialities' }

但是创建的表单是:

<form accept-charset="UTF-8" 
   action="/course_groups" 
   class="simple_form course_group" 
   controller="specialities" 
   id="new_course_group" 
   method="post">

我的预期是:

<form accept-charset="UTF-8" 
   action="/specialities" 
   class="simple_form course_group" 
   controller="specialities" 
   id="new_course_group" 
   method="post">

Answer 1

尝试使用 :url选项，而不是包含 :action & :controller就在 html 哈希中。我会将您的示例重新编写为:

<%= simple_form_for @course_group, 
    :url => url_for(:action => 'create', :controller => 'specialities'),
    :method => 'post' do |f| %>
