python - Django - 表 xxx 没有名为 xxx 的列

Question

当我尝试将表单保存在 View 中时，我遇到了问题，然后我看到错误:表 core_order 没有名为 Responsible_group_id 的列。我进行了迁移、刷新等。但这并不能解决我的问题。

Forms.py:

class CreateForm(forms.ModelForm):

    class Meta:
        model = Order
        fields = ('responsible_group', 'responsible_user')

    def __init__(self, request_client_id, *args, **kwargs):
        super(CreateForm, self).__init__(*args, **kwargs)
        self.fields['responsible_group'].choices = BLANK_CHOICE + tuple(
            Group.objects.all().values_list('id', 'name').exclude(id=1)) 
        self.fields['responsible_user'].choices = BLANK_CHOICE

        self.fields['responsible_group'].widget.attrs.update({
            'type': 'text',
            'class': 'form-control input-block-level',
        })
        self.fields['responsible_user'].widget.attrs.update({
            'type': 'text',
            'class': 'form-control input-block-level',
        })

models.py:

class Order(models.Model):
    responsible_group = models.ForeignKey(Group)
    responsible_user = models.ForeignKey(User, blank=True, null=True, related_name='+')
    created_date = models.DateTimeField(auto_now_add=True, editable=False)
    finished_date = models.DateTimeField(null=True, blank=True)
    modified_date = models.DateTimeField(auto_now=True)
    (...)

views.py:

def order_create(request, request_client_id):

        if request.method == 'POST':
            form_order = CreateForm(request_client_id, request.POST)
            if form_order.is_valid():
                obj = form_order.save(commit=False)

                (...)

                obj.responsible_group = form_order.cleaned_data["responsible_group"]
                obj.responsible_user = form_order.cleaned_data["responsible_user"]

                obj.save()

                # Redirect to Client profile
                return HttpResponse('')

尝试删除迁移文件，然后重新运行 python manage.py makemigrations 和 python manage.py migrate。
