ruby-on-rails - rails :method=>:patch doesn't work

Question

所以，我有这个表格声明:

<%= form_for 'students_list', {:url => update_students_list_stream_url(@stream), :method=>:patch}  do |students_list_form| %>

正如 API 文档中所述，但这导致我出错:

No route matches [POST] "/streams/26/edit-students-list"

所以它仍然尝试发布，即使我的 HTML 输入有:

<input type="hidden" name="_method" value="patch" />

从 Rails 指南:

Rails works around this issue by emulating other methods over POST with a hidden input named "_method", which is set to reflect the desired method:

我很困惑
