class Template(models.Model):
    name = models.CharField(max_length=135, blank=True)
    pattern = models.ForeignKey(Pattern)
    create_time = models.DateTimeField()
    creator = models.CharField(max_length=135, blank=True)

我想要 :

Template.objects.extra(where=[str]).order_by('create_time')

并根据外键“模式”区分结果。这个怎么做?谢啦~
