使用我目前拥有的代码，我的图像过去可以加载，但现在它们没有，我不知道为什么。在我的 Artist 模型中，我包含了一个 ImageField。这让我可以上传图像并将其存储在我的媒体目录中名为“艺术家”的目录中。
class Artist(models.Model):
name = models.CharField(max_length=40)
genre = models.CharField(max_length=20)
location = models.CharField(max_length=20)
bio = models.TextField()
photo = models.ImageField(upload_to='artists', null=True, blank=True)
def __str__(self):
return self.name
正如您在下面看到的，我的图像“fontaines.png”已上传并存储在 /media/artists/ 中。

所以到目前为止一切看起来都很好，但是当我在本地运行服务器时，它会在我的终端上显示图像的页面上这样说：
Not Found: /media/artists/fontaines.png
[19/Apr/2020 15:32:01] "GET /media/artists/fontaines.png HTTP/1.1" 404 1759
我试图弄清楚为什么图像无法加载，但我无法破解它。可以的话请帮忙，谢谢。
