Hi I made a simple example that is not the original but is giving me the  
same issue…  
I create a method on my controller… and make it so I cant sent him data  
to work with and return me the results…  
but I keep getting that is an underfined method…! ;-(

error:

ActionView::TemplateError (undefined method `paco’ for  
#\<#Class:0x2b1dcace86d8:0x2b1dcafabc80\>) on line #10 of  
app/views/rosteritems/\_amigos.rhtml:  
7:  
8:   
9: \<% grupo.each do |amigo| %\>  
10: lolo \<%= paco(amigo.jid) %\>  
11: \<%= amigo.jid %\>  
12: \<% end %\>  
13:

the controller method paco:

def paco(msg)

```
    end

```

obviosly this is simple as it gets for the example…  
I don’t know why is saying that paco is undefined!

thanks.

Try putting your method in a helper instead of controller (either  
application\_helper.rb or rosteritems\_helper.rb)
