用户统计

需求分析

  • 展示当前总人数,月活跃人数,日活跃人数
  • 使用图表的形式展示活跃曲线

实现准备

  • static/admin/user_count.html 拖到 templates/admin/ 目录下

代码实现

  • 实现思路:

    • 月新增数:获取到本月第1天0点0分0秒的时间对象,然后查询最后一次登录比其大的所有数据
    • 日新增数:获取到当日0点0分0秒时间对象,然后查询最后一次登录比其大的所有数据
    • 图表查询:遍历查询数据每一天的数据(当前天数,减去某些天)
  • 后端查询数据实现

@admin_blu.route('/user_count')
def user_count():
    # 查询总人数
    total_count = 0
    try:
        total_count = User.query.filter(User.is_admin == False).count()
    except Exception as e:
        current_app.logger.error(e)

    # 查询月新增数
    mon_count = 0
    try:
        now = time.localtime()
        mon_begin = '%d-%02d-01' % (now.tm_year, now.tm_mon)
        mon_begin_date = datetime.strptime(mon_begin, '%Y-%m-%d')
        mon_count = User.query.filter(User.is_admin == False, User.create_time >= mon_begin_date).count()
    except Exception as e:
        current_app.logger.error(e)

    # 查询日新增数
    day_count = 0
    try:
        day_begin = '%d-%02d-%02d' % (now.tm_year, now.tm_mon, now.tm_mday)
        day_begin_date = datetime.strptime(day_begin, '%Y-%m-%d')
        day_count = User.query.filter(User.is_admin == False, User.create_time > day_begin_date).count()
    except Exception as e:
        current_app.logger.error(e)

    # 查询图表信息
    # 获取到当天00:00:00时间

    now_date = datetime.strptime(datetime.now().strftime('%Y-%m-%d'), '%Y-%m-%d')
    # 定义空数组,保存数据
    active_date = []
    active_count = []

    # 依次添加数据,再反转
    for i in range(0, 31):
        begin_date = now_date - timedelta(days=i)
        end_date = now_date - timedelta(days=(i - 1))
        active_date.append(begin_date.strftime('%Y-%m-%d'))
        count = 0
        try:
            count = User.query.filter(User.is_admin == False, User.last_login >= day_begin,
                                      User.last_login < day_end).count()
        except Exception as e:
            current_app.logger.error(e)
        active_count.append(count)

    active_date.reverse()
    active_count.reverse()

    data = {"total_count": total_count, "mon_count": mon_count, "day_count": day_count, "active_date": active_date,
            "active_count": active_count}

    return render_template('admin/user_count.html', data=data)
  • 修改 templates/admin/index.html 中【用户统计】链接
<li><a class="icon022" href="/admin/user_count" target="main_frame">用户统计</a></li>
  • 前端页面渲染数据实现
<div class="spannels">
    <div class="spannel scolor01">
        <em>{{ data.total_count }}</em><span></span>
        <b>用户总数</b>
    </div>
    <div class="spannel scolor02">
        <em>{{ data.mon_count }}</em><span></span>
        <b>用户月新增数</b>
    </div>
    <div class="spannel2 scolor03">
        <em>{{ data.day_count }}</em><span></span>
        <b>用户日新增数</b>
    </div>
</div>
...


xAxis : [
    {
        name: '今天',
        type : 'category',
        boundaryGap : false,
        data : {{ data.active_date | safe }}
    }
],        
yAxis : [
    {
        name: '活跃用户数量',
        type : 'value'
    }
],      
series : [
    {
        name:'active',
        type:'line',
        smooth:true,
        itemStyle: {normal: {areaStyle: {type: 'default'}, color: '#f80'}, lineStyle: {color: '#f80'}},
        data: {{ data.active_count }}
    }],
