Question

我有CreateView创建Model1对象。我需要创建其他对象（在此视图中），它将Model1作为ForeignKey。

from .models import Model1, Model2

class Creating(CreateView):
    model = Model1
    fields = ["field"]

    def form_valid(self, form):
        # how to create here something like this:
        # model2 = Model2.create(field_from_model2 = Model1_object_which_was_created_in_this_View?)
        return super(Upload, self).form_valid(form)

为super()调用CreateView时，对象将另存为self.object。您可以拨打super()，但不会返回响应。然后，您可以使用self.object创建第二个对象。最后，返回响应。

class Creating(CreateView):
    model = Model1
    fields = ["field"]

    def form_valid(self, form):
        response = super(Creating, self).form_valid(form)
        object2 = Model2.objects.create(
            model1=self.object,
            # other fields
        )
        return response

Django，如何在CreateView中手动创建对象
