Question

我遇到以下情况：

forms.py

class DocumentUploadForm(forms.Form):
    file = forms.FileField(
        validators=[validate_file_extension],
        required=True
    )
    author = forms.CharField(required=True)

    class Meta:
        model = Document
        fields = ['file', 'author']

models.py

class Document(models.Model):
    file = models.FileField(upload_to='documents/')
    author = models.CharField(max_length=50)
    date = models.DateField(auto_now=False, auto_now_add=True)
    imported = models.BooleanField(default=False)

views.py

if request.method == "POST":
    form = DocumentUploadForm(request.POST, request.FILES)

    if form.is_valid():
        # author = request.POST.get('author', None)
        # if author is None:
        #     return HttpResponseRedirect("/")
        # document = Document(file=request.FILES['file'], author=author)
        # document.save()
        form.save() # no save() method !!

错误：'DocumentUploadForm' object has no attribute 'save'

我不喜欢通过自己创建document对象并填写所有必要信息的方式。这导致了许多我不想要的错误处理。所以我看了https://docs.djangoproject.com/en/1.8/topics/http/file-uploads/#handling-uploaded-files-with-a-model

他们描述了我实施的确切方式，但我不知道为什么会出现AttributeError。

任何帮助都会很好！ aronadaal

您的表单似乎混合了Form和ModelForm代码，而继承自基本Form (forms.Form)。 AFAIK，基本的Django Form没有save()方法。要使用简单的form.save()，请使用ModelForms。你已经使用了Meta类，所以你应该能够继承ModelForm并删除表单的前两行：

class DocumentUploadForm(forms.ModelForm):
    class Meta:
        model = Document
        fields = ['file', 'author']

有关详情，请参阅ModelForm文档：https://docs.djangoproject.com/en/1.10/topics/forms/modelforms/ 以及这个问题的答案：object has no attribute 'save' Django

Django文件上传：上传表单没有保存方法
