保存后从 Django 表单获取模型 ID

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()

如何获取我刚刚保存的模型（或模型）的 idsomeForm?

由于行为模型表单.save https://github.com/django/django/blob/399c6ac7cc1b95c249b964d6c6d47ded43943fde/django/forms/models.py#L351是返回实例，您可能希望在 customSave 方法中返回实例

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

然后您可以访问实例上的 pk 或 id

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