Android-使用Glide访问Django服务器上的静态文件失败

我有以下

Django

型号：

class MyAccount(AbstractBaseUser):
    ...
    profile_picture = models.FileField(upload_to='Images/',default='Images/placeholder.jpg')
    ... 

当用户创建此帐户时，他将获得一个默认占位符图像。用户注册（为特定用户创建

MyAccount

实例）按预期工作

但我的Android应用程序无法在请求时获取占位符图像。在我的本地

Django

开发服务器上，我得到以下错误：

[17/Nov/2020 12:54:34] "GET /media/Images/placeholder.jpg HTTP/1.1" 404 2569
Not Found: /media/Images/placeholder.jpg

为什么会这样？图像

占位符.jpg

存在，那么怎么可能找不到该文件呢

在Android Studio的

LogCat

输出中，我在过滤okhttp时遇到了类似的错误。您还可以看到注册已正确完成，但未找到文件：

2020-11-17 13:54:32.8525825-5924/com.example.project D/OkHttp:您是否将以下命令保存在settings.py中

MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

我已设置媒体根目录，因为文件位于媒体文件夹中。请将此文件添加到配置文件图片的默认值旁边：-blank=True。看看这是否有效，然后告诉我。
