- 理解上下文
- 使用模板语言
- 制作分页器
Note
理解上下文
views.py
render(request,x.html,context) 传入三个函数
{{ id }} , context = {id1='',id2='', }
models.py
from mongoengine import *
模板语言
{% for i in Artinfo%}
{% endfor %}
分页器
from django.core.paginator import Paginator
Aim
用58的数据库和昨天的模板生成一个博客
Result
Code
models.py
- 链接数据库
- 写个类,里面所有属性和数据库条目名字同名
-
meta = 'collection' : 'sheet_out'链接对于collection
from django.db import models
from mongoengine import *
from mongoengine import connect
connect('ilw',host='localhost',port = 27017)
class ArtiInfo(Document):
price = StringField() # 注意和数据库中的名字一样
place = StringField()
title = StringField()
comment = StringField()
url = StringField()
meta = {'collection':'sheet_out'}
# if use list
# tags = ListField(StringField())
views.py
- 设置每页上限
- 生成一个翻页对象
- 加载当前页
from django.shortcuts import render
from django.core.paginator import Paginator
from django_web.models import ArtiInfo
def index(request):
limit = 3
paginator = Paginator(ArtiInfo.objects,limit)
page = request.GET.get('page',1)
loaded = paginator.page(page) # 注意这里是小写的
content = {'ArtiInfo' : loaded} # 注意这里不能直接写字典
return render(request,'index.html',content)
index.html__生成条目
- for && endear
- {{代替id}}代替
{% for it in ArtiInfo %}
<div class="posts">
<h1 class="content-subhead">Recent Posts</h1>
<section class="post">
<header class="post-header">
<img class="post-avatar" alt="Eric Ferraiuolo's avatar" height="48" width="48" src={% static "img/common/ericf-avatar.png" %}>
<h2 class="post-title">{{ it.title }}</h2>
<p class="post-meta">
By <a class="post-author" href="#">{{ it.place }}</a> under <a class="post-category post-category-js" href="#">{{ it.comment }}</a>
</p>
</header>
<div class="post-description">
<p>
<a href="{{ it.url }}"> {{ it.price }} </a>
</p>
</div>
</section>
{% endfor %}
如果用到list
{% for tag in item.tags %}
<span class="meta-cate">{{ tag }}</span>
{% endfor %}
index.html__生成页码
</div class = "main-content-pagitor">
{% if ArtiInfo.has_previous %}
<a href="?page={{ ArtiInfo.previous_page_number }}">Pre</a>
{% endif %}
<span>{{ ArtiInfo.number }} of {{ ArtiInfo.paginator.num_pages }}</span>
{% if ArtiInfo.has_next %}
<a href="?page={{ ArtiInfo.next_page_number }}">Next</a>
{% endif %}
</div>
总结
这一章模板内容相对较多...不过对于自己博客理解加深了一层还是很开心啦~~
