Question

当我尝试将其保存在视图中时，我的表单出现问题然后我看到错误：表core_order没有名为responsible_group_id的列。我做了迁移，冲洗等。但这不能解决我的问题。

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。
