怎么制作网页查询Excel

 

 

一.项目背景

   本项目利用Django Web框架制作一个简易版的网页查询数据，数据源为Excel表格
   数据，通过该项目让大家了解到Django与办公自动化的结合，也给大家拓展一种数据展
示思路。

 

二.实现过程

1.创建项目
  1）创建项目（django-admin startproject 项目名称）和app（python manage.py startapp myapp）
  2）在settings.py中添加配置信息
  3）启动项目（python manage.py runserver）

2.获取数据
  1）read_excel读取Excel数据（如下图所示）
  2）前端构建form表单
  3）获取页面传过来的参数

 

{% load static %}

{% csrf_token %}

姓名: {% if stu_name %} {%else %} {% endif %}

{{ data|safe }} 【注】以上是test.html文件中代码

from django.shortcuts import render

import  pandas as pd
#获取数据
def get_data(request):
    #读取excel文件
    data=pd.read_excel('test.xlsx')
    #如果请求方式是POST请求
    if request.method=='POST':
        #获取输入值
        value=request.POST.get('name')
        #判断是否为空
        if value=='':
            #如果为空，返回原始数据，并且将前台页面输入置为空
            return render(request, 'test.html', {'data': data.to_html(index=False),'stu_name':''})
        else:
            #查取姓名，此处为模糊查询
            data_query=data[data['姓名'].str.contains(value)]
            #获取数据，将查到的数据和输入框值返回页面
            return render(request,'test.html',{'data':data_query.to_html(index=False),'stu_name':value})
    else:
        #如果是GET请求，直接返回所有数据
        return render(request, 'test.html', {'data':data.to_html(index=False)})

【注】以上是views.py文件中代码

3.展示数据
  1）配置url（如下图）
  2）配置css文件
  2）表格可视化

 

.data{
    text-align:center
}

.data_query{
    align:center
}

【注】以上是test.css文件中代码

 

查询前结果展示

 

模糊查询后结果展示
