1.创建项目和应用后，首先在settings.py文件中配置mysql数据库，并创建数据库[省市区的sql文件，网上很多]
2.创建models模型，进行数据迁移
3.创建template模板文件area1.html
4.进行urls路由配置
5.编辑views视图函数
1.modles.py
class AreaInfo(models.Model): atitle = models.CharField(max_length=30) aParent = models.ForeignKey(‘self‘, null=True, blank=True)
2.urls.py
from django.conf.urls import url from . import views urlpatterns=[ url(r‘^area1/$‘, views.area1), url(r‘^province/$‘, views.province), url(r‘^city_(\d+)/$‘, views.city), url(r‘^county_(\d+)/$‘, views.county), ]
3.views.py
from django.shortcuts import render from .models import AreaInfo from django.http import HttpResponse, JsonResponse def area1(request): return render(request, ‘booktest/area1.html‘) # 获取省数据 def province(request): provinceList = AreaInfo.objects.filter(aParent__isnull=True) list1 = [] for item in provinceList: list1.append([item.id, item.atitle]) return JsonResponse({‘data‘: list1}) # 获取市数据 def city(request, pid): print(pid) cityList = AreaInfo.objects.filter(aParent_id=pid) list1 = [] for item in cityList: list1.append([item.id, item.atitle]) return JsonResponse({‘data‘: list1}) # 获取区县数据 def county(request, pid): print(pid) countyList = AreaInfo.objects.filter(aParent_id=pid) list1 = []for item in countyList: list1.append([item.id, item.atitle]) return JsonResponse({‘data‘: list1})
4.area.html
<html>
<head>
<title>省市区列表</title>
<script type="text/javascript" src="/static/js/jquery-1.12.4.min.js"></script>
<script>
$(function () {
//获取所有省份
$.get(‘/province/‘, function (dic) {
pro = $(‘#pro‘)
$.each(dic.data, function (index, item) {
pro.append(‘<option value=‘ + item[0] + ‘>‘ + item[1] + ‘</option>‘);
})
})
//获取市信息
$(‘#pro‘).change(function () {
$.get(‘/city_‘ + $(this).val() + ‘/‘, function (dict) {
city = $(‘#city‘);
city.empty().append(‘<option value="">请选择市</option>‘);
$(‘#county‘).empty().append(‘<option value="">请选择区县</option>‘);
$.each(dict.data, function (index, item) {
city.append(‘<option value=‘ + item[0] + ‘>‘ + item[1] + ‘</option>‘);
})
});
});
//获取区县信息
$(‘#city‘).change(function () {
$.get(‘/county_‘ + $(this).val() + ‘/‘, function (dict) {
county = $(‘#county‘);
county.empty().append(‘<option value="">请选择区县</option>‘);
$.each(dict.data, function (index, item) {
county.append(‘<option value=‘ + item[0]+ ‘>‘ + item[1] + ‘</option>‘);
})
})
});
})
</script>
</head>
<body>
<select id="pro">
<option value="">请选择省</option>
</select>
<select id="city">
<option value="">请选择市</option>
</select>
<select id="county">
<option value="">请选择区县</option>
</select>
</body>
</html>
5.setting.py配置mysql数据库
DATABASES = { ‘default‘: { ‘ENGINE‘: ‘django.db.backends.mysql‘, ‘NAME‘: "area", ‘HOST‘: "127.0.0.1", ‘PORT‘: 3306, ‘USER‘: "root", ‘PASSWORD‘: ‘123456‘, } }
