django：图像数据无法从表单保存到数据库

Question

我已经在尝试修复这个错误几天了。我将 User 扩展为多了一个 Image 字段，但是，图像本身并没有保存到 /media/profile 路径中。如果我从管理面板添加图像，该图像将显示在前面/用户（个人资料图像）中，它也将被创建到所需的路径 /media/profile 中。我假设我的代码在我创建用户并另外添加路径的地方是错误的，因为如果我不添加路径，它将查看图像的根媒体文件夹。

custom_user = Profile.objects.create(user = user, profile_image= 'profiles/'+today_path+'/'+profile_image)

这是我的第一个 Django 项目，它几乎完成了，只是这个错误我无法修复它。对于如何修复它，我将不胜感激。谢谢，谢谢，谢谢！

Answer 1

在你的views.py中使用这个

 profile_image = request.Files['profile_image']

在html中

<form action="{% url 'register' %}" method'POST' enctype="multipart/form-data">

而不是

 profile_image = request.POST['profile_image']

告诉我它是否有效
