最近的几天时间内，主要是进一步开发SDUVJ的contest的其他功能中，并在最终完成了contest的基本的开发，并实现了基本的代码提交界面，接下来需要进一步完善其功能并改善性能。

Contest的实现代码####

在views.py中完成了了 对contest前端请求进行处理的函数

def contest(req):
    search = req.GET.get('search')
    if search:
        query = Contest.objects.filter(Q(name__icontains=search) | Q(uid__username__icontains=search))
    else:
        query = Contest.objects.all()
    pg = req.GET.get('pg')
    if not pg:
        pg = 1
    pg = int(pg)

    max_cnt = query.count()
    start = max(pg - PAGE_NUMBER_EVERY_PAGE, 1)
    end = min(pg + PAGE_NUMBER_EVERY_PAGE, max_cnt)

    lst = query[(pg - 1) * LIST_NUMBER_EVERY_PAGE:pg * LIST_NUMBER_EVERY_PAGE]

    return ren2res('contest.html', req, {'page': range(start, end + 1), 'list': lst})

同时，contest的界面如下,已经可以实现在contest中显示问题的详细说明界面：
