Now each instance of "Vehicle" has some attributes pertaining to the "vehicle" but it also has a reference to instance of one of automobiles class, where "automobiles" can be one of the many models like "car", "boat", "plane" etc...

I'm attempting to construct a Django application that models an existing set of tables. These tables all have the same fields, plus custom fields per table. What I'm wanting to do is model this structure, and have records save to a particular table based on what table model they are attached to. These tables can be created quite often,...

This is an extremely naive question. As you can tell, it comes from someone who doesn't know much about either databases or Django. What are the advantages of using ForeignKeys in Django? Maybe an example will help me understand better. I have tables like this already: City: id = IntegerField() # e.g. 15 name = CharField() # ...
Howdy, I am trying to figure out how to use proxy classes in Django. I want to receive a queryset where each object belongs to a proxy class of a common super class so that I can run custom sub-classed methods with the same name and my controller logic doesn't need to know or care about which kind of Proxy model it is working with. One ...
