通過使用bootstrap框架，并配合Django自帶的Paginator分頁組件即可實(shí)現(xiàn)簡單的分頁效果。
1.創(chuàng)建MyWeb項(xiàng)目
|
1
|
python manage.py startapp MyWeb |
2.修改settings.py配置文件,導(dǎo)入我們的app的名字，去掉csrf這個(gè)選項(xiàng)

|
# 屏蔽一項(xiàng)MIDDLEWARE = [ #'django.middleware.csrf.CsrfViewMiddleware']# 新增一項(xiàng)TEMPLATES = [ 'MyWeb.apps.MywebConfig'] |
3.來urls.py里面寫一條路由，名字就叫index/映射到views.index函數(shù)下處理此請求
|

6
|
from MyWeb import viewsurlpatterns = [ path('admin/', admin.site.urls), path('index/', views.index)] |
4.最后在myweb里面的views.py設(shè)置一個(gè)視圖函數(shù),最后運(yùn)行
|

6
|
from django.shortcuts import renderfrom django.shortcuts import HttpResponsefrom MyWeb import modelsdef index(requests): return HttpResponse("abcd") |
5.配置數(shù)據(jù)庫文件models.py并設(shè)置以下內(nèi)容

|
from django.db import models# 創(chuàng)建用戶表class User(models.Model): id = models.AutoField(primary_key=True) username = models.CharField(max_length=32) password = models.CharField(max_length=32) |
6.更新數(shù)據(jù)庫與數(shù)據(jù)表
|
1
2
|
python manage.py makemigrations # 將你的數(shù)據(jù)庫變動(dòng)記錄下來(并不會(huì)幫你創(chuàng)建表)python manage.py migrate # 將你的數(shù)據(jù)庫變動(dòng)正在同步到數(shù)據(jù)庫中 |
7.增加一個(gè)新的view并使用rand()函數(shù).
首先在urls.py中增加路由

|
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)] |
其次在view.py視圖中增加生成函數(shù).

from django.shortcuts import renderfrom django.shortcuts import HttpResponsefrom MyWeb import modelsimport random# 首頁def index(requests): return HttpResponse("abcd")# 生成測試數(shù)據(jù)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") |
啟動(dòng)django并訪問http://127.0.0.1:8000/rand/等待數(shù)據(jù)生成結(jié)束.
8.在templates模板中，新增一個(gè)page.html頁面。

9.最后在路由曾以及view中增加對應(yīng)的URL以及路由函數(shù).
首先在urls.py中增加一條新路由.

接著在views.py中增加一個(gè)page函數(shù).

準(zhǔn)備就緒之后，直接訪問http://127.0.0.1:8000/page即可看到分頁顯示效果.
