提问by Blankman
I want to have a form_for @user, but post to a custom action in the users controller.

How can I do this?

回答by Austin
form_for @user, :url => url_for(:controller => 'mycontroller', :action => 'myaction')
or
或者
form_for @user, :url => whatever_path
回答by Peter Lee
The following works for me:
以下对我有用：
form_for @user, :url => {:action => "YourActionName"}
回答by Szymon B?aszczyński
I have done it like that
我已经这样做了
<%= form_for :user, url: {action: "update", params: {id: @user.id}} do |f| %>
Note the optional parameter idset to user instance id attribute.
请注意id设置为用户实例 id 属性的可选参数。

Alternatively the same can be reached using form_tagwith the syntax:
或者，可以使用form_tag以下语法达到相同的目的：
form_tag({controller: "people", action: "search"}, method: "get", class: "nifty_form")
# => '<form accept-charset="UTF-8" action="/people/search" method="get" class="nifty_form">'
As described in http://guides.rubyonrails.org/form_helpers.html#multiple-hashes-in-form-helper-calls
如http://guides.rubyonrails.org/form_helpers.html#multiple-hashes-in-form-helper-calls 中所述

new syntax
新语法
<%= form_for :user, url: custom_user_path, method: :post do |f|%>
<%end%>
回答by Aditya Anand Krishna
If you want to pass custom Controller to a form_for while rendering a partial form you can use this:
如果您想在渲染部分表单时将自定义控制器传递给 form_for，您可以使用以下命令：
<%= render 'form', :locals => {:controller => 'my_controller', :action => 'my_action'}%>
and then in the form partial use this local variable like this:
然后以部分形式使用这个局部变量，如下所示：
<%= form_for(:post, :url => url_for(:controller => locals[:controller], :action => locals[:action]), html: {class: ""} ) do |f| -%>
