I have just started up grading to Rails 3. mail\_to no longer works,  
you just get a lot of garbage. With what do I replace it?

Thanks

The mail\_to helper is still present in edge Rails, so I’m not sure what  
is  
going wrong. Can you provide an example of your invocation, and what it  
is  
outputting?

I am using Rails 3 Beta 3. The code is:

\<%= mail\_to(supplier.email, h(supplier.email), :subject =\> “Bathroom  
Direct Order:”, :encode =\> “javascript”) %\>

This has worked fine up till Rails 2.3.5. Below is what now appears in  
the view:

Guidance will be most welcome.

Regards,

Paul

Isn’t that rails obfuscating the mailto link so that parsers cannot  
harvest email addresses so easily? Does the mailto link work if you  
follow it?

Hey Paul,

That javascript looks correct. mail\_to should return an html\_safe  
string. Escaped html indicates it isn’t.

So if the problem is that the html is being escaped, then this is a  
bug. file a ticket on the rails lighthouse.

To get around the bug, use \<%=raw mail\_to(…) %\> or \<%=  
mail\_to(…).html\_safe %\>

Regards  
Kieran

Hi Kieran,

Thanks for that. The raw option worked. I will file a ticket on the  
rails lighthouse.
