My problem is simple. I have a function “translateTo(lang)” that i  
need to call in my show\_data.rhtml file. The function that i need to  
call returns a string that i need to print out on my show\_data.rhtml  
page.

Should i define the function in the show\_data\_controller.rb? or some  
were else?

What commands should i have in the show\_data.rhtml?

show\_data.rhtml file  
…  
…  
…  
\<%= translateTo(@trans)%\> \<%# What shall i do to make this line work  
%\>  
…  
…

Hi, you should define the in the application\_helper.rb if it is to be  
used by all views or show\_data\_helper if it is only to be used with  
views of show\_data.

Good luck,
