Business ID
Business Name
Business Revenue
Date
这是示例数据：
Business ID | Business Name | Business Revenue | Date
1 B1 1000 2012-10-13
2 B2 20000 2013-10-16
1 B1 2000 2013-04-13
2 B2 24000 2014-09-02
我想获取所有具有最新日期的企业。
这是我想要的输出：
Business ID | Business Name | Business Revenue | Date
1 B1 2000 2013-04-13
2 B2 24000 2014-09-02
我已经尝试过这个：
model.objects.filter(date__gte = date.today()).order_by('business_id', '-date')
这为我提供了一组企业，每个组的顶部都有最新的业务。如何省略其余行？我需要一些帮助
我有10个文本框,现在我想检查单击按钮时它们都不是空的.我的代码是:
