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
|

5
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 views
urlpatterns = [
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 render
from django.shortcuts import HttpResponse
from MyWeb import models
def 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
|
1
2
3
4
5
6
7
8
9
|
from django.contrib import admin
from django.urls import path
from MyWeb import views
urlpatterns = [
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.
|
1
2
3
4
5

7
8
9
10
11
12
13
14

21
|
from django.shortcuts import render
from django.shortcuts import HttpResponse
from MyWeb import models
import 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。

</ul>
</nav>
<div style="text-align: center;" class="alert alert-dark">
统计: {{ currentPage }}/{{ paginator.num_pages }} 共查询到:{{ paginator.count }} 条数据 页码列表:{{ paginator.page_range }}
</div>
</body>
</html>

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 admin
from django.urls import path
from MyWeb import views
urlpatterns = [
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 render
from django.shortcuts import HttpResponse
from MyWeb import models
import random
from 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.
