Something like:  
autolink “Come to htttp://www.example.com”, href\_options = {:class =\>  
“example\_class”}

or

autolink “Come to htttp://www.example.com”, href\_options =  
{class=“example\_class”}

Haven’t really tried.

link\_to(name, options = {}, html\_options = nil,  
\*parameters\_for\_method\_reference)

so that would be

link\_to “mylink”, { :controller =\> “mycontroller”, :action =\>  
“myaction” }, { :class =\> “myclass” }

becomes

[mylink](http://mysite.com/mycontroller/myaction)

But you still need to use auto\_link (auto\_link\_urls), when it’s an  
external link, right?

i don’t see how auto\_link has anything to do with his question. he  
asked about adding a class attribute using link\_to

and to answer your question, no. autolink just replaces urls and/or  
email addresses in a string with the appropriate anchor tag. doesn’t  
matter where the url goes.

Can you use link\_to when you want to link to an external site at all?  
[http://www.imdb.com/bestmovieever/img/2.jpg](http://www.imdb.com/bestmovieever/img/2.jpg) ? That’s why I used  
auto\_link, filters through and makes a link of [http://whatever](http://whatever).

auto\_link “go here: [http://www.yahoo.com](http://www.yahoo.com) and send an email to  
removed\_email\_address@domain.invalid”

translates to

"go here: [http://www/yahoo.com](http://www.yahoo.com) and  
send an email to \<a href=“mailto:removed\_email\_address@domain.invalid\>removed\_email\_address@domain.invalid”

link\_to “go here” “[http://www.yahoo.com](http://www.yahoo.com)”

translates to

“[go here](http://www.yahoo.com)”

 

there’s a difference. one replaces urls and email addresses with  
anchor tags in a string, the other generates an anchor tag from a name  
and url (and any options).
