Is it possible to determine which action call the function ?

In example, func\_test in ApplicationController could determine which  
action from SiteController is calling her ?

in class ApplicationController I have

def func\_test  
if ( calling from index )  
return “1” end

if ( calling from contact )  
return “2” end  
end

and in class SiteController

def index  
@var = func\_test  
end

def contact  
@var = func\_test  
end

Thanks

if action\_name == ‘index’

I can’t check this at the moment, but I think Ruby supports this:

def test  
caller  
end

test # should give the object that called test

[http://www.ruby-doc.org/docs/ruby-doc-bundle/Manual/man-1.4/function.html#caller](http://www.ruby-doc.org/docs/ruby-doc-bundle/Manual/man-1.4/function.html#caller)

Although, for your case, action\_name is probably more suitable 🙂

No. action\_name is not Ruby or ROR functionnality

Yes just test it, return an error. I need to pass an arguement ?

action\_name is an attribute of class AtionController::Base. It does  
not require an argument. Can you post the exception stack trace?

class TestController  
def test  
render :text =\> action\_name  
end  
end

Works fine for me.
