将Django的FileField设置为现有文件

将Django的FileField设置为现有文件

如果要永久执行此 *** 作，则需要创建自己的FileStorage类

import osfrom django.conf import settingsfrom django.core.files.storage import FileSystemStorageclass MyFileStorage(FileSystemStorage):    # This method is actually defined in Storage    def get_available_name(self, name):        if self.exists(name): os.remove(os.path.join(settings.MEDIA_ROOT, name))        return name # simply returns the name passed

现在在模型中，使用修改后的MyFileStorage

from mystuff.customs import MyFileStoragemfs = MyFileStorage()class SomeModel(model.Model):   my_file = model.FileField(storage=mfs)
