当删除具有ImageField字段的对象时，图像文件未被删除
我有一个模型图片与 ImageField 。删除 Picture 的实例时， ImageField 中设置的文件不会被删除。
I've got a model Picture with an ImageField. When deleting an instance of Picture, the file set in the ImageField is not deleted.
这是一个bug吗？如何执行？
Is it a bug? How can I do it?
删除与 FileField s和 ImageField 在Django 1.3中有意删除。请参阅门票＃6456 。 Django广泛使用事务来防止请求发生错误的数据损坏。如果删除事务被回滚，则在文件从文件系统中删除后，您现在有一个记录指向不存在的文件。所有要求自动删除的票据已经被简要标记为不会修复，所以这不会改变。
Deletion of files associated with FileFields and ImageFields was intentionally removed in Django 1.3. See ticket #6456. Django uses transactions extensively to prevent data corruption if something goes wrong with the request. If a deletion transaction is rolled-backed, after the file has been deleted from the filesystem, then you now have a record pointing to a non-existent file. All tickets asking for automatic deletion to return have been summarily marked "Won't Fix", so this is not going to change.
