Django——Paginator分页功能练习
作者：互联网
1、路由urls.py
from django.contrib import admin
from django.urls import path
from app01.views import index
urlpatterns = [
path('admin/', admin.site.urls),
path('index/',index)
]
2、数据库表模型models.py
from django.db import models
# Create your models here.
class Book(models.Model):
name = models.CharField(max_length=100)
author = models.CharField(max_length=20)
price = models.IntegerField()
dsp = models.CharField(max_length=100)
3、数据库配置settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'HOST': '127.0.0.1',
'PORT': 3306,
'USER': 'root',
'PASSWORD': '1',
'NAME': 'demo'
}
}
4、视图函数views.py
from django.shortcuts import render
from app01.models import Book
from django.core.paginator import Paginator #导入Paginator分页器
def index(request):
book_all_list = Book.objects.all() #获取所有的书籍数据
p = Paginator(book_all_list,15) #实例化分页对象
page = request.GET.get('page',1) #获取GET方法传递过来的页码数，没有则默认为 1
current_page = int(page) #传过来的page是一个字符串，需要转换成int类型
book_object = p.page(current_page) #获取第current_page页的对象
book_list = book_object.object_list #获取第current_page页的对象的元素列表
return render(request,'index.html',{'book_list': book_list,'p': p,'book_object': book_object})
5、前端页面index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>测试</title>
<style>
.content{
width: 100%;
}
.tb1{
width: 80%;
margin-left: 100px;
}
</style>
</head>
<body>
<div class="content">
<table border="1px" class="tb1">
<tr>
<th>序号</th>
<th>书名</th>
<th>作者</th>
<th>价格</th>
<th>描述</th>
</tr>
{# 遍历展示当前页的数据 #}
{% for book in book_list %}
<tr>
<td>{{ book.id }}</td>
<td>{{ book.name }}</td>
<td>{{ book.author }}</td>
<td>{{ book.price }}</td>
<td>{{ book.dsp }}</td>
</tr>
{% endfor %}
</table>
</div>
<div style="margin-left: 100px;margin-top: 20px;">
{# 如果当前页有上一页，则可以通过上一页发送GET请求传递page参数，需要从views中传入当前页的对象book_object #}
{% if book_object.has_previous %}
<a href="/index/?page={{ book_object.previous_page_number }}">上一页</a>
{% endif %}
{# 获取分页对象的页码列表并遍历，需要从views中传入分页对象p #}
{% for num in p.page_range %}
<a href="/index/?page={{ num }}">{{ num }}</a>
{% endfor %}
{# 如果当前页有下一页，则可以通过下一页发送GET请求传递page参数，需要从views中传入当前页的对象book_object #}
{% if book_object.has_next %}
<a href="/index/?page={{ book_object.next_page_number }}">下一页</a>
{% endif %}
</div>
</body>
</html>
6、效果（没有添加样式，只是实现功能，所以页面比较丑！！！）
