I'm not clear on what you mean by "key". Foreignkey? Or for
instance, an encryption key stored in two tables? I'm left to guess
you mean a foreignkey.
In this case, the second 'table' you refer to could have a foreignkey
relating it back to the first table. If this is what you mean,
then ...
Table 1: Child
- id: AutoField
- fn: CharField
- ln: CharField
Table 2: Evaluation
- id: AutoField
- child: ForeignKey(Child)
- results: CharField
Each would have a corresponding Form with all fields.
Then in the request.POST processing...
child_form = childForm(request.POST)
eval_form = evalForm(request.POST)
if child_form.is_valid() and eval_form.is_valid():
new_child = child_form.save()
eval_form = evalForm(request.POST, instance=new_child)
eval_form.save()
Keep in mind, this always creates a new record in Child table, since
the childForm was instantiated without an instance. But that's
different topic anyway.
Also, if you need to access the pk of the new_child, you simply access
it via new_child.pk
i.e.
new_child = child_form.save()
new_pk = new_child.pk
There is another way, but it depends a bit on the design of your
models.
hint: get object (if it exists) from second table, and update the
corresponding field
