Question

尝试在本地提供用户上传的文件时出现404错误。我已经从论坛上尝试了很多建议，但我无法让它发挥作用。这是我在日志中看到的错误。图像可以正确上传到媒体/图像，但是当我尝试使用相同的图像时，我找不到404。我试图把绝对路径放在一边也没用。有人可以帮帮我吗？感谢

Answer 1

在UITableView时尝试提供MEDIA_ROOT并在urls.py投放。

<强> models.py

DEBUG=True

<强> settings.py

foto = models.ImageField(upload_to='images/', null=True, blank=True)

<强> urls.py

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

Answer 2

我希望您正确看到上传的文件。

对于本地开发，请尝试在您的基础urls.py

中添加以下内容

if settings.DEBUG is True:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

无法让图像在django中工作
