山东大学-VirtualJudge-总结7

在过去的几天时间里面，我主要集中精力实现Contest 的的Rank以及Status功能

Rank实现代码####

###前端






###后台
def contest_rank(req, cid):
    if req.is_ajax():
        contest = Contest.objects.get(id = cid)
        if contest.private:
            if req.user.is_superuser==False and req.user.info not in contest.accounts.all() :
                return JsonResponse("{}")
        rank_cache = contest.rank
        # print("rank_cache:")
        # print(rank_cache)
        status_list = Status.objects.filter(cid = cid).filter(runid__gt = contest.last_submit_id).order_by("time")
        # print("status_list")
        # print(status_list)
        rank_dict = json.loads(rank_cache)
        # print("rank_dict")
        # print(rank_dict)
        statsinfo = {}
        pos = 0
        problem_list = contest.get_problem_list()
        length = len(problem_list)

        
        if contest.last_submit_id==0:
            rank_dict["statsinfo"] = [{} for i in range(length)]
            for item in problem_list:
                rank_dict["statsinfo"][pos] = {"probid" : chr(pos + 65) ,"acNum" : 0, "tryNum" : 0}
                statsinfo[item[2].title] = {"pos" : pos}
                pos += 1
        else:
            for item in problem_list:
                statsinfo[item[2].title] = {"pos" : pos}
                pos += 1

        for item in status_list:
            if item.user.is_staff :
                continue
            name = item.user.username
            contest.last_submit_id = max(contest.last_submit_id, item.runid)
            if name not in rank_dict.keys():
                rank_dict[name] = {"name" : name, "solved":0, "penalty":0, "probs" : [{"failNum" : 0, "acNum" : 0, "acTime" : 0} for i in range(length)]}

            pos = statsinfo[item.pro.title]["pos"]

            if item.result == 3: #Waiting
                break

            if item.result == 0: #Accepted
                rank_dict["statsinfo"][pos]["acNum"] += 1
            rank_dict["statsinfo"][pos]["tryNum"] += 1

            if rank_dict[name]["probs"][pos]["acNum"] == 0:
                if item.result == 0:
                    rank_dict[name]["probs"][pos]["acNum"] += 1
                    rank_dict[name]["probs"][pos]["acTime"] = dateToInt(item.timec - contest.start_time, 1)
                    rank_dict[name]["penalty"] += 20 * rank_dict[name]["probs"][pos]["failNum"] + dateToInt(item.timec - contest.start_time, 0)
                    rank_dict[name]["solved"] += 1
                else:
                    rank_dict[name]["probs"][pos]["failNum"] += 1
        contest.rank = json.dumps(rank_dict)
        # print("contest.rank")
        # print(contest.rank)
        contest.save()
        return JsonResponse(rank_dict)

Status实现代码####

###前端



    {% for item in status_list %}

        
            {% ifequal item.pro.isCCF True %}
                 
        {% else %}
            {% ifequal item.result "Compilation Error"%}
            
            {% else %}
            
            {% endifequal %}
            {% endifequal %}
            {% ifequal item.user.id user.id %}
                
            {% else %}
            {% ifequal user.is_staff True %}
            
            {% else %}
            
            {% endifequal %}
            {% endifequal %}
            
    {% endfor %}

    {% for id in page %}
        

            {{ id }}
            
        
    {% endfor %}




###后台
def contest_status(req, cid):#has understood
    if req.is_ajax():
        contest = Contest.objects.get(id=cid)
        t = loader.get_template('contest/contest_status.html')
        status_list = Status.objects.filter(cid=cid).order_by('-time')#need change
        if contest.private:
            if req.user.is_superuser==False and req.user.info not in contest.accounts.all() :
                status_list = []
        pg = req.GET.get('pg')
        if not pg:
            pg = 1
        pg = int(pg)

        max_cnt = status_list.count() // 20 + 1
        start = max(pg - PAGE_NUMBER_EVERY_PAGE, 1)
        end = min(pg + PAGE_NUMBER_EVERY_PAGE, max_cnt)

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

        # content_html = t.render(Context({'status_list': lst, 'page': range(start, end + 1), 'contest_id': cid, 'user': req.user}))
        # return HttpResponse(content_html)
        return render(req,'contest/contest_status.html',{'status_list': lst, 'page': range(start, end + 1), 'contest_id': cid, 'user': req.user})
    else:
        raise Http404
