My use case is that I'll have multiple users trying to update a set of objects and I want to make sure that any user committing a change has knowledge of the existing state. I was going to model that with a version number so an update would look like:
update table set col=foo, col1=bar where id=pknum && version_number=<version I read> Desired result are the following:: --If a user has the correct previous version the update goes through --if they don't have the correct previous version it should do nothing (I'll throw an exception or return something to the upper layer to indicate the fact that the user needs to try again from the latest version...) My question is how can I do an update like the above in Django? It looks like the save API hides the fact whether it is insert or update; however I can easily determine this myself (haven't found a way that I can add additional criteria on the update). I saw the following patch: http://code.djangoproject.com/ticket/2705 And that could maybe meet my needs but I'm wondering if there is any existing way to accomplish this without having to patch Django? (hoping I'm missing some existing way to accomplish this) Please let me know if you have any suggestions.
