Django的。如何设置默认选项使用通用CreateView

Question

模型：

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

观看次数：

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

形式：

class MyForm(ModelForm):

    class Meta:
        model = MyModel
        fields = '__all__'

我如何在表单中设置选项列表上的默认值或第一个值>

您可以这样使用initial：

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

或像这样：

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,
        }

希望能帮助到你！
