Question

我有一个“个人资料”表单，该表单接受用于显示用户个人资料图片的图像。

我没有提交表单的问题，但是在访问管理面板时，我看到文件尚未保存。

即使想到，它也在request.POST中发送：

“照片”：['es_usted_inteligente.jpg']}>

SIGNUP REQUEST POST:  <QueryDict: {'csrfmiddlewaretoken': ['SXoar0hPxsKCcMgFG1lJ5XoxjCzbEEqa9x5livVw4M0m9ZB25SGKmL3IUogJnxHz'], 'first_name': ['a'], 'last_name': ['gonzales']
, 'username': ['agonzales'], 'dni': ['744484848'], 'phone_number': ['89898989'], 'birthdate_month': ['1'], 'birthdate_day': ['1'], 'birthdate_year': ['1980'], 'email': ['agon

ing_department': ['San Martín'], 'shipping_province': ['El Dorado'], 'shipping_district': ['Shatoja'], 'photo': ['es_usted_inteligente.jpg']}>

profile_form.cleaned_data：

“照片”：无}

  profile_form.cleaned_data: {'dni': '48494949', 'phone_number': '9898989', 'birthdate': datetime.date(1980, 1, 1), 'shipping_address1': 'Urb. La Merced Mz.G Lot.32', 'address

更新1 ：

将request.FILES添加到后：

    user_form = SignUpForm(request.POST, request.FILES)
    profile_form = ProfileForm(district_list, province_list, department_list, request.POST, request.FILES)

我在request.POST中找不到属性照片：

但是现在，profile_form.cleaned_data至少具有deault pic而不是None：

Answer 1

您需要提取文件，因此需要user_form = SignUpForm(request.POST, request.FILES)。

还要确保在hmtl的表单声明中包含enctype="multipart/form-data"。像<form id="projectForm" method="POST" enctype="multipart/form-data" action="">

图片在request.POST中发送，但在form.cleaned_data中清除
