在前面的基础上，连接mongoDB数据库，将数据库的信息显示在页面上，并可以翻页查看。
1.app项目下的models.py文件的设计
from django.db import models
from mongoengine import *
# Create your models here.
class ItemInfo(Document):
title = StringField()
url = StringField()
pub_data = StringField()
area = ListField(StringField())
cate = ListField(StringField())
look = StringField()
time = StringField()
price = IntField()
meta = {'collection': 'info_sheet'}
2.views.py文件
from django.shortcuts import render
from app_one.models import ItemInfo #引入models文件的内容
from django.core.paginator import Paginator #分页
def home(request):
limit = 10
item_info = ItemInfo.objects
paginator = Paginator(item_info, limit)
page = request.GET.get('page', 1)
loaded = paginator.page(page)
content = {'ItemInfo': loaded}
return render(request, 'pure_index_paginator.html', content)
3.settings.py文件
STATIC_URL = '/static/'
STATICFILES_DIRS = (os.path.join(BASE_DIR, 'static'),)
from mongoengine import connect #在后面添加这两行连接数据库
connect('gan', host='127.0.0.1', port=27017) #‘gan’是装表单的数据库
4.html文件
{% load static %}
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta name="description" content="A layout example that shows off a blog page with a list of posts.">
