After trying to get this to work for a while and searching around I am truly stumped so am posting here... I want to make some functions in classes that I am writing for django as generic as possible so I want to use getattr to call functions such as the one below in a generic manner:
the way I do it that works (non-generic manner):
from django.db.models import get_model
mymodel = get_model('appname', 'modelname')
dbobject = mymodel.objects.all()
one of my attempts create this in a generic manner, still not working, it does return something back but its not the proper object type so that i can get the data from it (its a database call for django)
ret = getattr(mymodel,'objects')
dbobject = getattr(ret,'all')

Okay, so it's cool that you can use getattr to get methods as well as properties, but how does that help us? Well, this can definitely be useful in keeping your code DRY if you have some common logic surrounding branching method calls.
The getattr() method returns the value of the named attribute of an object. If not found, it returns the default value provided to the function.
Python getattr() function. Python getattr() function is used to get the value of an object's attribute and if no attribute of that object is found, default value is returned.
Python getattr() function is used to access the attribute value of an object and also gives an option of executing the default value in case of unavailability of the key. Parameters : obj : The object whose attributes need to be processed. key : The attribute of object.
You forgot to call the result.
dbobject = mymodel.objects.all()
Accesses the method mymodel.objects.all and then calls it.
ret = getattr(mymodel,'objects')
self.dbobject = getattr(ret,'all')
accesses the method mymodel.objects.all but does not call it.
All you need is to change the last line to:
self.dbobject = getattr(ret,'all')()
