I need to set up a demo site for users to try a web app before signing up. The demo would be based on production code, however, it would require minor code changes: connection to a demo database, automatic creation/login of a new guest account for each user, etc.
The obvious solution is to replicate my code base as a second demo website and edit as necessary. Keeping the demo code in sync with production code is easy enough by adding a branch in subversion. I'm less than thrilled, however, at the prospect of having to do two updates on my server (production and then demo) every time I push code from development to production.
Initially I thought I might be able to replicate the website through a module. It's unclear if this is possible, however.
Is there a mechanic in Yii to execute an altered version of a website (config file and selected controllers)?
