Question

我有一个Django项目。

这是我的模特：

class Task(models.Model):
    class Meta:
        db_table = 'task'

    title = models.CharField(max_length=64)

这是我的表格：

class TaskForm(forms.Form):

    def __init__(self, *args, **kwargs):
        user = None
        if 'user' in kwargs:
            user = kwargs.pop('user')

        super(TaskForm, self).__init__(*args, **kwargs)

    title = forms.CharField(max_length=64)

这是我的观点：

def create(request):
    args = {}
    args.update(csrf(request))

    if request.POST:
        form = TaskForm(request.POST)

        if form.is_valid()

            Task(title=form.cleaned_data['title']).save()

            return redirect('/tasks/user')

        else:
            args = {'error': form.errors}
            return render_to_response('index.html', args,
                                      context_instance=RequestContext(request))
    else:
        args['form'] = TaskForm(user=request.user)
        return render_to_response('create_task.html', args,
                                  context_instance=RequestContext(request))

但如果我要添加任务，我会收到错误： 'function'对象没有属性'model' 在行

if form.is_valid():

回溯：

  1215. except (ValueError, TypeError, self.queryset.model.DoesNotExist):

Exception Type: AttributeError at /tasks/create/ Exception Value: 'function' object has no attribute 'model'

我哪里错了？

我得到了同样的错误，似乎“form = TaskForm（request.POST）”不创建一个对象而是一个函数，但如果你从模型的字段创建表单它应该工作。试试这样：

class TaskForm(forms.Form):
    def __init__(self, *args, **kwargs):
        user = None
        if 'user' in kwargs:
            user = kwargs.pop('user')

    super(TaskForm, self).__init__(*args, **kwargs)

class Meta:
    model= Task
    fields={'title',}

'function'对象没有属性'model'
