我建议仔细阅读文档,特别是:https ://docs.djangoproject.com/en/dev/ref/models/options/#django.db.models.Options.ordering
class Tag(models.Model):
test_case_counter = models.IntegerField(default=0)
my_date_field = models.DateField(auto_now=True,auto_add=True)
class Meta: # notice indentation
ordering = ['my_date_field']
app_label = 'project'
