    摘要:上文号称【最为简明实用的Django上手教程】介绍了django基本概念、配置和相关操作。相信通过上文的阅读,基本明白django运行机制和操作。假设你现在通过dome和相关书籍已经基本理解django这台机器的运行。下一步如何像asp.net、Jsp,PHP等常规网站开发,进行前后台交互呢?又如何采用较为简洁美观的前端框架进行设计呢?假设你需要配置多个数据库怎么办?静态文件单独存放需要哪些配置?针对这些配置有哪些便利?最后,假设你又是一名对数据开发很感兴趣的,且学过一些机器学习,数据挖掘,自然语言处理,云计算等技术之一,想挖掘分析数据并进行可视化,怎么办?本文就是针对这些问题开始的。(本文原创编著,转载注明出处:号称最为简明实用的Django上手教程(下)

    1 前景回顾


    系统环境:WIN10 64bit

    开发环境:sublime+Anaconda
    数据库:Mysql 5.6.17
    语言:python3.5
    框架:django1.11+Bootstrap
    可视化工具:Highchart|Echarts|plotly|Bokeh(采用Echarts)

    2 静态文件配置操作


     (1)静态static文件夹的配置。

    在analysis文件夹下创建:analysis/static和analysis/templates文件夹,其中:

    ① static:包括,css,js,img,font,files等文件,使用时需要配置,页面开头添加{% load static %}

    ② templates:包含web的html静态页面,django1.10之后会默认识别

    (2)打开xmjc_analysis/setting.py修改如下:

    1
    2
    STATIC_URL = '/static/'
    STATIC_ROOT = os.path.join(BASE_DIR, "static")

    (3)打开xmjc_analysis/urls.py修改如下:

    # 配置加载静态页面
    from django.conf import settings
    from django.conf.urls.static import static
     
    urlpatterns = [
        url(r'^admin/', admin.site.urls),
     
        url(r'^index/$', analysis_views.index,name='index'),# 首页
         
    ]+ static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

    (4) 在基模板(后文详细介绍)base页面开头添加{% load static %}

     (5 )xmjc_analysis/views.py修改如下:

    1

    '''
    第一个页面
    author:白宁超
    site:http://www.cnblogs.com/baiboy/
    '''
    #coding:utf-8
    from django.shortcuts import render
    from django.http import HttpResponse
    def index1(request):
        name = request.GET['name']
        return HttpResponse(u"欢迎"+name+",进入第一个Django页面!")
     
    def index(request):
        '''项目统计分析平台主页'''
        return render(request,'xmjc/index.html') # 首页

    然后在xmjc_analysis/urls.py下添加访问

    3 结合Bootstrap和页面模板前端设计


      (1)什么是Bootstrap?

    Bootstrap是一组用于网站和网络应用程序开发的开源前端框架,包括HTML、CSS及JavaScript的框架,提供字体排印、窗体、按钮、导航及其他各种组件及Javascript扩展,旨在使动态网页和Web应用的开发更加容易。 Bootstrap是GitHub上面被标记为“Starred”次数排名第二最多的项目。Starred次数超过105,000,而分支次数超过了47,000次。

    ps:前端框架,所有的插件依赖于 jQuery。所以必须在插件文件之前引用 jQuery

    ----维基百科

    (2)Bootstrap学习资料

    ① 官网下载地址:http://getbootstrap.com/
    ②  中文网下载地址:http://www.bootcss.com/
    ③ w3c学习网站:https://www.w3cschool.cn/bootstrap

    (3)引入 Bootstrap

    <!-- 引入 Bootstrap -->
    <link href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css" rel="stylesheet">
    <!-- jQuery (Bootstrap 的 JavaScript 插件需要引入 jQuery) -->
    <script src="https://code.jquery.com/jquery.js"></script>

    <!-- 精简版 -->
    <link href="http://libs.baidu.com/bootstrap/3.0.3/css/bootstrap.min.css" rel="stylesheet">
    <script src="//libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
    <script src="//libs.baidu.com/bootstrap/3.0.3/js/bootstrap.min.js"></script>

    具体知识点总结参考文章:【前端知识十分钟预览之学习札记

    (4)基于Bootstrap的页面模板设计

    ①  base.html 可以视作母模板,其中包括:

    {% load static %}   放在页面最顶层,用于识别静态文件

    <head></head>      放入的编码和基本信息以及css文件(js文件放在页面尾部,提高用户体验)

    侧边栏                     引用③文件,便于修改和管理。

    1
    2
    3
    4
    5
    <!-- 侧边栏 -->
    <div id="sidebar" class="sidebar">
        {% include 'xmjc/nav.html' %}
    </div>
    <!-- /侧边栏 -->

    页面内容设计       {% block content %}{% endblock %}占块符号

    1
    2
    3
    4
    5
    <div class="row col-lg-12">
             {% block content %}
                 <p>此处为主要内容</p>
              {% endblock %}
    </div>

    底部     存放js文件 

    复制代码
    <!DOCTYPE html>
    <html>
    <head>
    {% load static %}
        <!-- meta的引用 -->
        <meta http-equiv="content-type" content="text/html; charset=UTF-8">
        <meta charset="utf-8">
        <meta name="author" content="bnc">
        <!-- CSS样式设计 -->
        <link rel="stylesheet" type="text/css" href="/static/bootstrap-dist/css/bootstrap.min.css"  />
        <link rel="stylesheet" type="text/css" href="/static/bootstrap-dist/css/bootstrap-theme.css"  />

        <!-- 表格 -->
        <link rel="stylesheet" type="text/css" href="/static/js/datatables/media/css/jquery.dataTables.min.css" />
        <link rel="stylesheet" type="text/css" href="/static/js/datatables/media/assets/css/datatables.min.css" />
        <link rel="stylesheet" type="text/css" href="/static/js/datatables/extras/TableTools/media/css/TableTools.min.css" />
    
        <!-- JQUERY,所有bootstrap依赖此js -->
        <script src="/static/js/jquery-2.0.3.min.js"></script>
        <!-- echarts -->
        <script src="/static/js/echarts/echarts.js"></script>

        #'app_name':'database_name',
        'app1''db1',
        'app2''db2',
    }

    (2)在project_name文件夹中存放 database_router.py 文件,内容如下:

    复制代码
    # -*- coding: utf-8 -*-
    from django.conf import settings
    
    DATABASE_MAPPING = settings.DATABASE_APPS_MAPPING
    
    
    class DatabaseAppsRouter(object):
        """
        A router to control all database operations on models for different
        databases.
    
        In case an app is not set in settings.DATABASE_APPS_MAPPING, the router
        will fallback to the `default` database.
    
        Settings example:
    
        DATABASE_APPS_MAPPING = {'app1': 'db1', 'app2': 'db2'}
        """
    
        def db_for_read(self, model, **hints):
            """"Point all read operations to the specific database."""
            if model._meta.app_label in DATABASE_MAPPING:
                return DATABASE_MAPPING[model._meta.app_label]
            return None
    
        def db_for_write(self, model, **hints):
            """Point all write operations to the specific database."""
            if model._meta.app_label in DATABASE_MAPPING:
                return DATABASE_MAPPING[model._meta.app_label]
            return None
    
        def allow_relation(self, obj1, obj2, **hints):
            """Allow any relation between apps that use the same database."""
            db_obj1 = DATABASE_MAPPING.get(obj1._meta.app_label)
            db_obj2 = DATABASE_MAPPING.get(obj2._meta.app_label)
            if db_obj1 and db_obj2:
                if db_obj1 == db_obj2:
                    return True
                else:
                    return False
            return None
    
        # for Django 1.4 - Django 1.6
        def allow_syncdb(self, db, model):
            """Make sure that apps only appear in the related database."""
    
            if db in DATABASE_MAPPING.values():
                return DATABASE_MAPPING.get(model._meta.app_label) == db
            elif model._meta.app_label in DATABASE_MAPPING:
                return False
            return None
    
        # Django 1.7 - Django 1.11
        def allow_migrate(self, db, app_label, model_name=None, **hints):
            print(db, app_label, model_name, hints)
            if db in DATABASE_MAPPING.values():
                return DATABASE_MAPPING.get(app_label) == db
            elif app_label in DATABASE_MAPPING:
                return False
            return None
    复制代码

    (3)使用操作

    复制代码
    # 查询
    YourModel.objects.using('db1').all()
    # 保存 或 删除
    user_obj.save(using='new_users')
    user_obj.delete(using='legacy_users')
    # 数据库同步
    python manage.py migrate --database=db2
    # 数据导出
    python manage.py dumpdata app2 --database=db2 > app2_fixture.json
    python manage.py dumpdata auth > auth_fixture.json
    # 数据库导入
    python manage.py loaddata app1_fixture.json --database=db1
    复制代码

    5  数据挖掘与可视化技术


     (1)设计思路

    调用Echarts进行可视化展示,其中数据来源于两个部分,直接调用一方面数据库的结构化数据,另一个方面分析处理非结构化数据。最终处理成json形式,最后结合ajax进行数据绑定展示。这里【数据挖掘|文本处理技术】不详细介绍,主要展示思想和流程。期望展示三个案例:柱形图、饼形图、数据表格。

    (2)数据前台展示,使用表单需要添加{%csrf_token%}

    (3)柱形图案例展示

    新建页面ksh.html,添加如下代码

    1
    2
    3
    4
    5
    <!-- 为ECharts准备一个具备大小(宽高)的Dom -->
    <div class="row">
        <div class="col-md-6 " id="test1" style="600px;height:400px;margin:0 auto">
        </div>
    </div>

    js代码:

    /*
    柱状图
    白宁超
    2017年8月4日17:20:42
     */
    // 基于准备好的dom,初始化echarts图表
    var myChart = echarts.init(document.getElementById('test1'));
    // 指定图表的配置项和数据
    var option = {
        title: {
            text: 'ECharts 入门示例'
        },
        tooltip: {},
        legend: {
            data:['销量']
        },
        xAxis: {
            data: ["衬衫","羊毛衫","雪纺衫","裤子","高跟鞋","袜子"]
        },
        yAxis: {
        },
        series: [{
            name: '销量',
            type: 'bar',
            data: [5, 20, 36, 10, 10, 20]
        }]
    };
    // 使用刚指定的配置项和数据显示图表。
    myChart.setOption(option);

    json数据:上面案例采用官方数据,只需要配置data即可,这个data的json数据,你可以通过数据挖掘技术后文本或者数据库梳理出绑定起来即可。如下所示:

    def xmjf(request):
        lnav="项目经费统计" # 可视化主题
        lcontent = "这里是可视化主题的描述->项目经费统计" # 可视化主题的描述
     
        data=[{"value": 55, "name"'优先55'},
             {"value": 70,  "name"'普通70'},
             {"value": 25,  "name""紧急25"}]
        data1 = [{"keys":"衬衫""values":5},
                {"keys":"羊毛衫""values":20},
                {"keys":"雪纺衫""values":36},
                {"keys":"裤子""values":10},
                {"keys":"高跟鞋""values":10},
                {"keys":"袜子""values":20}]
        return render(request,'xmjc/xmjf.html',{'lnav':lnav,'lcontent':lcontent,'data':data,'data1':data1})
