篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了图像在request.POST中发送，但在form.cleaned_data中清理相关的知识，希望对你有一定的参考价值。
我有一个配置文件表单，它接受用于显示用户配置文件图片的图像。
我提交表单时没有问题，但是当访问管理面板时，我可以看到该文件尚未保存。
甚至想，它是在request.POST发送：
'photo'：['es_usted_inteligente.jpg']>
SIGNUP REQUEST POST: <QueryDict: 'csrfmiddlewaretoken': ['SXoar0hPxsKCcMgFG1lJ5XoxjCzbEEqa9x5livVw4M0m9ZB25SGKmL3IUogJnxHz'], 'first_name': ['a'], 'last_name': ['gonzales']

profile_form.cleaned_data：

class Meta:

更新1：
将request.FILES添加到：
user_form = SignUpForm(request.POST, request.FILES) profile_form = ProfileForm(district_list, province_list, department_list, request.POST, request.FILES)
我在request.POST找不到属性照片：
SIGNUP REQUEST POST: <QueryDict: 'csrfmiddlewaretoken': ['8xcGwGg7z86OclANaEYwdB49u5hrCjOy7gFKSgoqmhxS0CmzeBIUgnYUdRyTnzqJ'], 'first_name': ['g'], 'last_name': ['gonzales']
, 'username': ['ggonzales'], 'dni': ['45484545'], 'phone_number': ['968484848'], 'birthdate_month': ['1'], 'birthdate_day': ['1'], 'birthdate_year': ['1980'], 'email': ['ggon
zales@gmail.com'], 'password1': ['caballo123'], 'password2': ['caballo123'], 'shipping_address1': ['Urb. La Merced Mz.G Lot.32'], 'address_reference': ['Tienda Roja'], 'shipp
ing_department': ['Huancavelica'], 'shipping_province': ['Castrovirreyna'], 'shipping_district': ['Castrovirreyna']>
但是现在，profile_form.cleaned_data至少有deault pic而不是None：
Profile Cleaned Data: 'dni': '45484545', 'phone_number': '968484848', 'birthdate': datetime.date(1980, 1, 1), 'shipping_address1': 'Urb. La Merced Mz.G Lot.32', 'address_re
ference': 'Tienda Roja', 'shipping_department': 'Huancavelica', 'shipping_province': 'Castrovirreyna', 'shipping_district': 'Castrovirreyna', 'photo': <ImageFieldFile: profil

答案
你需要拿起文件，所以你需要user_form = SignUpForm(request.POST, request.FILES)。
此外，请确保您在hmtl中的表单声明中有enctype="multipart/form-data"。像<form id="projectForm" method="POST" enctype="multipart/form-data" action="">之类的东西
以上是关于图像在request.POST中发送，但在form.cleaned_data中清理的主要内容，如果未能解决你的问题，请参考以下文章
