Question

view.py

someForm = SomeForm(request.POST)
...
someForm.customSave(request.user)

forms.py

class SomeForm(ModelForm):

    class Meta:
        model = Some

    def customSave(self,user):
        lv = self.save(commit=False)
        lv.created_by = user
        lv.save()

How can I get the id of the model (or the model) I have just saved from someForm?

Answer 1

Since the behavior of ModelForm.save is to return the instance, you might want to return the instance in your customSave method

def customSave(self, user):
    lv = self.save(commit=False)
    lv.created_by = user
    lv.save()
    return lv

then you can access the pk or id on the instance

inst = someForm.customSave(request.user)
inst.pk or inst.id
