Hi,

I’m trying to make unsubscribe link and currently got a route like  
this:

map.unsubscribe ‘/unsubscribe/:email’, :controller =\> ‘foo’, :action  
=\> ‘bar’

However when I put an email address in the url, it generates “no  
route” error. It’s probably caused by the dot in email addresses.

I’m using Rails 1.2.6. Any ideas how to fix it?

Thanks in advance

Hi,

Use a different char for the dot in the request. I’m assuming you’re  
generating the unsubscribe link.

Thanks.  
Unfortunately I can’t modify the url, at least not the email part -  
users are redirected to this unsubscribe url from another app that  
simply adds user’s email at the end of the url.

Try:

map.unsubscribe ‘unsubscribe/\*email’, :controller =\> ‘foo’, :action =\>  
‘bar’

instead. You’ll have the email address in params[:email][0] as the  
email part will create an array.
