Hello, I try this :

## in application\_helper.rb

def lnk bla  
return link\_to bla, { :controller =\> bli , :action =\> “blo” , :id  
=\> “blu” }  
end

## in file.rhtml

\<%= lnk “yo!” %\>

This return an error. There is a way to do this or something similar, or  
this is completly impossible ?

Thanks

I think you mean :controller =\> “bli”, right?

In the future, it’s nice to give the actual error you receive when  
stuff doesn’t work.

If there really is a line break before ‘=\>’ in your source code, then  
that’s a syntax error.

I took your code and pasted it into my app, removing that line break,  
and it compiles fine, apart from a warning that you should put parens  
around the method arguments. I have similar methods in my own code.

The link break in the middle of the statement, does that exist in the  
actual code. Does that would definitely cause the error.
