I’m constantly amazed at how productive you can be with rails. It simply lets you work on typical webapp problems at a much higher level. At 8z, we had a web application and a customer support team. Occasionally the customer support person had to ‘impersonate’ a normal user to troubleshoot an issue. We built a piece of software that let them assume that role. (We called it ‘sudo‘, obviously.) It’s been a few years, but as I recall it was complicated and error prone, lived on a different domain and wasn’t fully functional.

I needed to add similar functionality to a rails web app, and was able to find a couple of gems that looked useful. I selected pretender, mostly on the basis of documentation and google search results placement. I followed the instructions, tweaked a few settings and was off to the races in about an hour.  (Note this isn’t a fair apples to apples comparison of the underlying technologies, due to the differences in available open source libraries between the mid 2000s and the late 2010s.)

Now, all this gem does is what it says it does. It lets a certain user or set of users in your application pretend to be another user. It doesn’t handle auditing or anything else you might want with an elevated privilege system.

But it does do what it does well.
