I had a chance to work on a project that used friendly_id. The gem was mostly great, but there were a few situations when it didn’t work as expected and I spent hours fixing it. I’m not a fan of reinventing the wheel either, but for my latest project I tried to implement SEO-friendly URLs just with what Rails has to offer. It turned out really easy and with many advantages over the gem.
