获取'字符串到 Django forms.FileField()

Question

我正在上传没有表单。 如果我通过<input type...> 上传，我的用户有一个 FileField，我没有问题。 但这对我的目的来说不是那么方便。

views.py

    def uploadaction2(request):
        f = forms.FileField() # this is my idea
        data = json.loads(request.body)
        # f.clean("data['data']") # error: file_name = data.name AttributeError: 'str' object has no attribute 'name'
        logger.error(type(data['data'])) #gives <class 'str'> and without the type the string that i want to save
        with open('newfile', 'w') as file:
            file.write(data['data'])
        request.user.file = file 
        request.user.save() # i get no error until this part

错误

Internal Server Error: ....  in pre_save
    if file and not file._committed:
AttributeError: '_io.TextIOWrapper' object has no attribute '_committed'

我想我必须将 json 字符串转换为 forms.FileField()，因为我不知道该怎么做。

Answer 1

    def uploadaction2(request):
        file = request.FILES.get('file') # set name to input
        request.user.file = file
        request.user.save()
