Dash-bootstrap-components Dash ui布局组件 https://dash-bootstrap-components.opensource.faculty.ai/

  • Python 3.8+
  • Redis :
    • 部署服务器:192.168.1.182
    • 部署服务器:192.168.1.174
    • 用户名密码:gpadmin/gpadmin
    • 主要配置文件: conf/hfx_dashboard.py
      • 主要包含:
        • greenplum 数据库连接配置
        • redis 连接配置
        • 项目主题配置
        • 其他(后续可能新增)
        • 主要包含路由路径常量定义

        如 sales_bymonth 表示:销售分析模块的月度分析页面

        每一个app的文件命名为:[ app_ ] 二元交易与 HFX 交易一样吗? 二元交易与 HFX 交易一样吗? 二元交易与 HFX 交易一样吗? + [app名称] + [后缀].

        每一个app对应于一个 URL 路径(不含基地址),其 URL 路径为 [模块名] + / + [页面名].

        每一个app对应于一个service文件,service文件命名为 [ srv_ ] 二元交易与 HFX 交易一样吗? 二元交易与 HFX 交易一样吗? + [app名称]

        如, 月度销售分析页面对于的service文件为 srv_sales_bymonth.py

        如 筛选组件的渠道组件, f_channel f: filter 表示筛选组件, channel 是渠道的意思

        回调函数命名规则为: [update_] + [图形作用_] + [graph]

        二元交易与 HFX 交易一样吗?
        组件 命名规则 示例 示例说明
        dbc.Button btn_[模块/组件]_[作用] btn_filter_submit 表示该button是用于过滤后提交查询
        dcc.Dropdown choices_[模块/组件]_[作用] choices_top_order 表示该下拉框是用于选择top组件排序
        dcc.Graph graph_[作用] graph_top 表示该图为排名图
        1. 每一个函数方法, 必须要有方法说明、方法参数、方法返回值都必须有说明,并且需要规定返回值类型(页面组件元素除外)

        在Windows 直接使用ide工具找到main.py 鼠标右键运行即可

        • apps/app_sales_bymonth_index.py
          • 主要包含代码说明: dash实例化
          • 主要包含代码说明: 所有的页面布局代码
          • 主要包含代码说明: 页面对应的回调函数
          • 例如 services/srv_sales_bymonth.py
            • 主要包含代码说明:全局缓存处理函数、数据计算处理函数、数据库连接查询函数

            第四步: 在 routers.py 下 注册访问路由

            注意:路由参数@blueprint.route('/')和 重定向 redirect(URL_SALES_BYMONTH) 不能一致

            例如,如果 @blueprint.route('/test') 配置的路由路径是/test ; 那么 redirect(URL_SALES_BYMONTH)中 URL_SALES_BYMONTH 的值不能为/test

            • flask_app.py
            • 示例(为省略后的代码,具体参看flask_app.py文件):

            由于数据库使用的是greenplum,greenplumn 又是基于postgresql的,所以连接驱动和postgresql连接驱动一致,都是使用 psycopg2 连接示例参考 utils/db_util:

            示例2: 使用pandas直接读取, 二元交易与 HFX 交易一样吗? 该方法返回的是一个Dataframe

            根据dash官方文档推荐,使用Flask-Caching + Redis来进行缓存,缓存的数据通过一个函数访问,该函数的输出由其输入参数缓存和键控 缓存使用示例:

            第三步: 将触发取数的值缓存到dcc.Store, 并以此触发缓存方法和其他的回调计算

            • 代码位置: apps/callbacks/app_sales_bymonth_callback.py
            • 在此方法中,Input参数会动态实时的调用此回调方法,State表示只取值,不触发回调。
            • 此函数表示点击提交按钮后,根据所有筛选值作为dcc.Store的值,会触发其他回调方法的计算

            • 具体内容位置在 services/srv_sales_bymonth.py.
            • 根据dcc.Store的值, 从数据库或者从缓存中取得计算数据
