Hi Chaps,

How can I check if the page is using a controllers action. for example i  
got a helper method that needs to know if a certain controller action is  
run on the page or not so as to display different content for it.

Thought it was just

code = “xyz” if Controllername.action?

Cheers,

Rog

If I correctly understood what you need, you may try using:

> Controller.action\_methods.include?params[:action]

Your views have access to the controller and method that rendered them  
via controller.controller\_name and controller.action\_name

e.g.,  
\<% if controller.controller\_name == ‘posts’ %\>  
\<% if controller.action\_name == ‘create’ %\>  
\<%= do whatever %\>  
\<% end %\>  
\<% end %\>

HTH,
