Re: Get pk before commit

Hi,

Could you explain the situation in a little more detail as I don't
quite follow what you mean. As far as I'm aware if you have something
like the following:

>>> my_inst = MyModel(foo="bar", ...)
>>> my_inst.save()

You'll have the pk at this point even if the transaction hasn't been
committed (providing you haven't specified a custom primary key
field). So you should be able to do:

>>> my_pk = my_inst.pk

and use this for the other field that you need to set. If the other
field is a foreign key to my_inst, then you should just be able to do:

>>> other_model_inst.related_object = my_inst
>>> other_model_inst.save()

I'm not sure how this is affected by transactions. Unless you have a
really good reason to, I'd let Django handle the transaction
management for you, then you don't need to worry about save points,
committing and rolling back.
