Django 。如何设置默认选项使用通用 CreateView

Question

型号:

class MyModel(model.Models)
   status = models.ForeignKey(Statuses, on_delete=models.PROTECT, null=True, blank=True)

浏览量:

class MyViewCreate(CreateView):
    model = MyModel
    form_class = MyFrom
    template_name = 'mymodel_form.html'

表格:

class MyForm(ModelForm):

    class Meta:
        model = MyModel
        fields = '__all__'

我如何在表单中设置默认值或选项列表中的第一个值>

Answer 1

你可以像这样使用initial:

class MyViewCreate(CreateView):
    model = MyModel
    form_class = MyFrom
    initial = {'status': '0'}
    template_name = 'mymodel_form.html'

或者像这样:

class MyViewCreate(CreateView):
    model = MyModel
    form_class = MyFrom
    template_name = 'mymodel_form.html'

    def get_initial(self):
        state = get_object_or_404(MyModel, some_field=some_value)
        return {
            'state':state,
        }
