I have a web application with Rails 4 where you have to log in to use it. Now I want a demo version of this app. By demo version I mean a version that has all the features of the original app but without the login. And all the demo data should (and can easyliy) be deleted from time to time (either automatically or manually).
With the original app up and running I want to implement the demo version with the least effort. Ideally I can use most of the original code without any changes. But changes to the original code on the other hand will be available in the demo version without any extra work.
My first idea was to implement the demo version just in the cache/session so if the session is expired, the data is deleteded as well. I canceled that idea due to the deep integration of ActiveRecord in the original app. I would have to re-code all the demo classes and/or build some abstract parent classes and so on.
The second idea was to simply use the original app but to add a flag to each demo account so that they can be distiguished from all the regular ones. I hesitate with this idea because I'm afraid to blow up my database (i.e. the tables that I use for the original app) with demo data leading to lower performance and higher cost/risk of wrong interpretations when evaluating the app data (e.g. how many accounts where created yesterday).
Do you have any ideas how to realize such a demo version in an elegant way? Smart approaches welcome!
