我的模型时:Django的 - 方法调用在管理删除FK
class Spectacle(models.Model):
title = models.CharField(max_length=100)
slug = models.SlugField(max_length=100 unique=False)
description = models.TextField()
class SpectacleGallery(models.Model):
spectacle = models.ForeignKey(Spectacle)
image = models.ImageField(upload_to=upload_path_handler, max_length=255, help_text=_(u'tylko pliki z rozszerzeniem .jpg'))
image_thumb = models.CharField(max_length=255, editable=False, blank=True, null=True)
def delete(self, *args, **kwargs):
image_thumb_abs = settings.MEDIA_ROOT + str(self.image_thumb)
# try to delete thumb and image
try:
remove(image_thumb_abs)
except Exception:
pass
try:
self.image.delete()
except Exception:
pass
super(SpectacleGallery, self).delete(*args, **kwargs) # Call the "real" delete() method.
#try to delete dir
try:
removedirs(settings.SPECTACLE_GALLERY_UPLOAD_PATH + str(self.spectacle_id))
except:
pass
现在管理员,当我从SpectacleGallery文件删除从磁盘和DB删除正常。问题是当我想删除眼镜。删除页面询问我是否确定删除眼镜和所有相关图像。我确认并且:删除数据库中的所有记录。不幸的是,SpectacleGallery中的文件不会被删除。我将其打印到SpectacleGallery中的delete()方法中。没有显示,所以我的问题是: 为什么删除方法不被调用时,以这种方式删除它?
