ruby-on-rails - How to see action of a webpage in Rails?

Question

Is there a field or method I can lookup within an .html.erb file that will tell me the current action used to render the page? This code would be in a partial. I'm looking for something like this:

<% if @action == :new %>
  this is new
<% end %>

Answer 1

是的，你有action_name并且controller_name为此目的。

但请注意：结果是一个字符串，而不是一个符号。

见说明。

Answer 2

你可以做这样的事情。

<% if params[:action] ==  "new" %>
  # do something here
<% end %>
