When saving a model, I need to be able to access its ID field like
this:
class MyModel:
...
def save(self, force_insert = False, force_update = False):
v = self.id
# Do something with v
super(MyModel, self).save(force_insert, force_update)
However, if the model is being created for the first time, self.id is
None, so I need a way to find out what the ID is going to be.
So far I've come up with this:
class MyModel:
...
def save(self, force_insert = False, force_update = False):
v = self.id
if not v:
if MyModel.objects.count() > 0: # Do other MyModel objects
already exist?
v = MyModel.objects.latest(field_name = 'id').id + 1
else:
v = 1
# Do something with v
super(MyModel, self).save(force_insert, force_update)
Am I calculating the correct ID here?
