Ever had the error `terminate called after throwing an instance of ‘int’` in Ruby on Rails? I have, and it’s been frustrating to no end. It was difficult to trace but eventually I found the cause. In my case it was caused by ImageScience version 1.1.3. Version 1.1.1 does not have this problem. Also, ImageMagick does not have it!
I am happy to announce a new version of dnsbl_check is underway. I’ve had some feedback about false positives and I have seen this happen myself now once. My proposed solution is to check to see if the method `logged_in?` returns true. When that’s the case, obviously the current user is OK and the filter should pass.
The method name is a defacto standard for Rails apps, but if you don’t have it you can easily create it in ApplicationController. This way you can wire it up for your site specifically (e.g. you have a Subscriber model that does the hard work, like I have with GO Magazine).
I am currently very busy but will release the new version in a little while.
