Django DateTimeField 指定日期筛选（How can I filter a date of a DateTimeField in Django）

class AnchorBindAgent(models.Model):

    主播绑定到代理，绑定规则

    proportion = models.FloatField(verbose_name="分成比例(%)", default=10, help_text="0 到 100 整数或小数")

    start_time = models.DateField(verbose_name="生效日期", default=timezone.now)
    end_time = models.DateField(verbose_name="失效日期", default=end_time_default)

    create_time = models.DateTimeField(verbose_name="创建时间", auto_now_add=True)  # timezone.now 不要加括号
    update_time = models.DateTimeField(verbose_name="更新时间", auto_now=True)
