Due to my little confidence with Django and my sheer horror at the thought of seriously messing up my beautiful project, I shall ask for proper advice/instructions here. The database that my Django project is sitting on top of has been changed (a few field types have been changed) and my models are now out-of-sync. Funnily enough, my Dj...

I've added to those generated files, given the scenario where I've added an attribute to a model entity and need to re-generate the interface/implementation files. Does ...

I'm getting started on a new MVC project where there are some peculiar rules and a little bit of strangeness, and it has me puzzled. Specifically, I have access to a database containing all of my data, but it has to be handled entirely through an external web service. Don't ask me why, I don't understand the reasons. That's just how it i...
Obviously MVC promotes separation of concerns. One thing we are struggling with is proper separation of Model from the datasource, with IDs being the main sticking point. The interfaces that define our model call for an ID of type X Currently the datasource is SQL server.. but what if it is an xml file for some reason and our ID is of...
