通过使用bootstrap框架，并配合Django自带的Paginator分页组件即可实现简单的分页效果。
1.创建MyWeb项目
|
1
|
python manage.py startapp MyWeb |
2.修改settings.py配置文件,导入我们的app的名字，去掉csrf这个选项

6
7
8
9
|
# 屏蔽一项MIDDLEWARE = [ #'django.middleware.csrf.CsrfViewMiddleware']# 新增一项TEMPLATES = [ 'MyWeb.apps.MywebConfig'] |
3.来urls.py里面写一条路由，名字就叫index/映射到views.index函数下处理此请求
|
1
2
3
4
5
6
|
from MyWeb import viewsurlpatterns = [ path('admin/', admin.site.urls), path('index/', views.index)] |
4.最后在myweb里面的views.py设置一个视图函数,最后运行
|
1
2
3
4
5
6
|
from django.shortcuts import renderfrom django.shortcuts import HttpResponsefrom MyWeb import modelsdef index(requests): return HttpResponse("abcd") |
5.配置数据库文件models.py并设置以下内容
|
1
2
3
4
5
6
7
|
from django.db import models# 创建用户表class User(models.Model): id = models.AutoField(primary_key=True) username = models.CharField(max_length=32) password = models.CharField(max_length=32) |
6.更新数据库与数据表
|
1
2
|
python manage.py makemigrations # 将你的数据库变动记录下来(并不会帮你创建表)python manage.py migrate # 将你的数据库变动正在同步到数据库中 |
7.增加一个新的view并使用rand()函数.
首先在urls.py中增加路由
|

7
8
9
|
from django.contrib import adminfrom django.urls import pathfrom MyWeb import viewsurlpatterns = [ path('admin/', admin.site.urls), path('index/',views.index), path('rand/',views.rand)] |
其次在view.py视图中增加生成函数.
|

11
12

from django.shortcuts import renderfrom django.shortcuts import HttpResponsefrom MyWeb import modelsimport random# 首页def index(requests): return HttpResponse("abcd")# 生成测试数据def rand(request): for i in range(1,1000): chars = [] pasd = [] for x in range(1,8): chars.append(random.choice('abcdefghijklmnopqrstuvwxyz')) pasd.append(random.choice('0987654321')) user = "".join(chars) pwd = "".join(pasd) models.User.objects.create(username=user, password=pwd) return HttpResponse("ok") |
启动django并访问http://127.0.0.1:8000/rand/等待数据生成结束.
8.在templates模板中，新增一个page.html页面。

9.最后在路由曾以及view中增加对应的URL以及路由函数.
首先在urls.py中增加一条新路由.

from django.contrib import adminfrom django.urls import pathfrom MyWeb import viewsurlpatterns = [ path('admin/', admin.site.urls), path('index/',views.index), path('rand/',views.rand), path('page',views.page)] |
接着在views.py中增加一个page函数.

from django.shortcuts import renderfrom django.shortcuts import HttpResponsefrom MyWeb import modelsimport randomfrom django.core.paginator import Paginator, EmptyPage, PageNotAnInteger# 首页def index(requests): return HttpResponse("abcd")# 生成测试数据def rand(request): for i in range(1,1000): chars = [] pasd = [] for x in range(1,8): chars.append(random.choice('abcdefghijklmnopqrstuvwxyz')) pasd.append(random.choice('0987654321')) user = "".join(chars) pwd = "".join(pasd) models.User.objects.create(username=user, password=pwd) return HttpResponse("ok")# 分页函数def page(request): user = models.User.objects.all() paginator = Paginator(user, 10) currentPage = int(request.GET.get("id",1)) if paginator.num_pages > 15: if currentPage-5 < 1: pageRange = range(1,11) elif currentPage+5 > paginator.num_pages: pageRange = range(currentPage-5,paginator.num_pages) else: pageRange = range(currentPage-5,currentPage+5) else: pageRange = paginator.page_range try: user_list = paginator.page(currentPage) except PageNotAnInteger: user_list = paginator.page(1) except: user_list = paginator.page(paginator.num_pages) return render(request,"page.html",{"user_list":user_list, "paginator":paginator, "page_range":pageRange, "currentPage":currentPage}) |
准备就绪之后，直接访问http://127.0.0.1:8000/page即可看到分页显示效果.
