因为模板没有计算功能,如果你必需要使用forloop来实现,那你可能需要使用自定义filter参考https://segmentfault.com/q/10... @register.filter def counter(value, page): pagesize = 10 return (page - 1) * pagesize + value #模板调用,1表示当前页码 {{ forloop.counter|counter:1 }} 有用2 回复 bb...

Cells were grown in sealed glass bottles, mixed with a stir bar while fresh media inflow was controlled by an electromechanical valve. A constant volume was maintained using a gravity-fed waste line. Optical density was measured using a LED and photodiode, which fed back to control the fresh...
I haven't touched the code for a while now but I remember this issue. I didn't care too much as it goes both ways. From my first post : Bees are counted as soon as they show in one image, hence some bees get counted multiple time as IN and OUT as they wander around the entran...
