Thanks guys for this helpfull discussion 2012/7/5 Tomas Neme <lacrymol...@gmail.com>: > [...] I assumed > he maybe doesn't know about abstract models because he said he's just > getting started programming (or at least on py/dj) and maybe he wasn't > sure what behavior he needed, and what were his options.
...although I was aware of the concept of abstract classes and abstract models, I just did not come up with the idea, that this could solve my problem. As long as I work from my django-app this will be a proper solution. And if somebody gets to work on the database directly, well it's one join more, but doable. > and from Tom's: > >> In the example, it is evident that the OP wants MTI, since he includes >> the foreign key links in the class definition - there is no clearer >> indicator than this! I'm afraid you do me too much honor. During trying the concepts of inheritance in django I just was never sure, what is done implicitely and what I have to specify. So I just thought "it might help and won't do any damage". As a site note, i programm several years now c++ and having a degree in CS, but I tend to solve these problems too much from the brain but from practice. That's why I thought, the data *must* be in the super class. Up to now I don't know if i will need the data to be in place, but till then I will solve the problem with the abstract super class. The big difference is, -as I see it- I will not get real polymorphism, as the base class would need to do the join on all it's child classes. Is that true? I just got it, it's the same question you just answered: > As I said before, the only thing this *really* depends on is in this > question: do you need to be able to do something in the lines of: > Fruit.objects.all()? So this helps me to solve it, just differently than I thought. (which actually would justify a title change ;-) ) Thanks again :-) Best regards, Daniel -- Daniel Walz - mcj...@gmail.com Bremen, Germany -- You received this message because you are subscribed to the Google Groups "Django users" group.
