Python django ImageField上载的问题

我的问题是我只能从管理面板上传图片。每当我尝试上传时，通过我制作的表单，图像似乎没有保存

免责声明：我知道这不是最吸引人的代码，但我是编程新手。对不起

根据您的代码，您编写了一个函数，用于为上载的文件生成新名称，但您没有使用它更改

profilbillede = models.ImageField('Profilbillede',
                                    upload_to='profile_pics/%Y-%m-%d/',
                                    null=True,
                                    blank=True)

profilbillede = models.ImageField('Profilbillede',
                                    upload_to=upload_to_location,
                                    null=True,
                                    blank=True)

至

profilbillede = models.ImageField('Profilbillede',
                                    upload_to='profile_pics/%Y-%m-%d/',
                                    null=True,
                                    blank=True)

profilbillede = models.ImageField('Profilbillede',
                                    upload_to=upload_to_location,
                                    null=True,

应该解决问题

您应该在此处提供尽可能多的代码详细信息，以缩小问题范围，以便人们能够更好地帮助您。你不能仅仅给出回购协议，让人们直观地搜索你做错了什么。是的，你是对的。我会改变的
