Google App Engine: appcfg.py rollback

Question

I'm using Windows 7 and for the life of me I cannot figure out how to call the rollback function on appcfg.py. All I want to know is what to type into the command prompt so I can rollback my app.

Answer 1

Try this: appcfg.py rollback <directory>

If your application myapp resides in C:\Users\Nilesh\Documents\ then directory path should be C:\Users\Nilesh\Documents\myapp

If you installed Google App Engine Launcher in your system, then installation path should be something like this C:\Program Files\Google\google_appengine

Now open the command prompt and type the following:

C:\Program Files\Google\google_appengine>appcfg.py rollback C:\Users\Nilesh\Documents\myapp

This will solve your issue. :)

Answer 2

The rollback command can rollback a transaction on the server, but you are unlikely to need to use that unless an update of your app failed for some reason. You should be getting some feedback from appcfg.py that such an action is required. Is that what you want to do? If so, just open a command prompt and type appcfg.py rollback.

Otherwise, please let us know what you are trying to accomplish by performing a 'rollback'.

try this : this was how I did it (all from the command line) which is a slightly simpler method, which achieved the same effect.....

If you use maven for deploying your app (with goal appengine:update), then you can also run maven with goal appengine:rollback. It solved the issue for me.
