基于 Rails 4 中新建和编辑表单的控制器操作的条件 [英] conditional based on the controller action for new and edit forms in Rails 4

问题描述

我在新视图和编辑视图中呈现了一个表单:

I have a form rendered in the new and edit views:

<%= simple_form_for(@course, html: {class: "form-horizontal"}) do |f| %>

由于我的编辑表单应该略有不同:simple_form_for([@category, @course])，有没有办法根据控制器操作(编辑或新建)编写条件?

Since my edit form should be slightly different: simple_form_for([@category, @course]), is there a way to write a conditional based on the controller action (edit or new) ?

# if controller action is new

<%= simple_form_for(@course, html: {class: "form-horizontal"}) do |f| %>

#if controller action is edit

<%= simple_form_for([@category, @course], html: {class: "form-horizontal"}) do |f| %>

推荐答案

您可以使用 action_name

<% if action_name == 'edit' %>
  #
<% else %>
  #
<% end %>

或者为了真正安全，也使用 controller_name

Or to be really safe, use controller_name also

<% if controller_name == 'cources' && action_name == 'edit' %>
