映像未存储在python django中的数据库mysql workbench iin中

我正试图从我的“产品表单”中将产品图像保存到数据库中。但是当我从管理部分插入值时，图像没有存储，此时值可以存储

型号.py

photo = models.ImageField(upload_to='profile_images', blank=True)

photo = forms.ImageField()

    success = False

来自

ProductForm

的视图处理将接收

request.FILES

中的文件数据，这是一个字典，包含

表单中每个
文件字段
（图像、文件等）的键

因此，上述表单中的数据可以作为
请求.FILES['photo']
访问，如果您的表单有效，那么为什么不将pprint放在photo中呢？我不明白..我必须将打印放在哪里？在
photo=product\u form.cleaned\u data['photo']
pprint.pprint（photo）`下面我添加了这一行，它显示了错误“未定义全局名称'pprint'”让我们。
