Can a action view invoke a methode of a controller then display its results

Hi,

Can an action view (a template) invoke a methode of a controller, then
display the results of the methode at the same template?

like:
if actionTwo return a simple string "xyz123"

and the action view looks like this:

<body>
   abcde
  <%= render(:action => :actionTwo) %>
</body>

Should the result html be
abcde
xyz123

Thanks you very much

You can call a method on the controller by:

@controller.method_call

so

<%= render(:action => @controller.actionTwo) %>

I think that will work. Not tested though.

Hi,

I have tried the @controller.actionTwo, but it doesn't work. I got the
following msg error:

You have a nil object when you didn't expect it!
The error occured while evaluating nil.actionTwo

I think, it doesn't recognize the contorller....

You can put a helper inside the controller:

class FooController < ApplicationController

  helper do
    def erase_harddisk
      "ouch!"
    end
  end

end

[inside foo.rhtml]

<%= erase_harddisk %>

However, it is strongly discouraged to put application logic
inside your view.
