models
class Img(models.Model): src = models.FileField(max_length=32,verbose_name='图片路径',upload_to='static/upload') title = models.CharField(max_length=16,verbose_name='标题') summary = models.CharField(max_length=128,verbose_name='简介') class Meta: verbose_name_plural = '图片' def __str__(self): return self.title
