动态URL
运行已经做好的博客框架, 会发现一个问题, 只有一个主页的空盒子, 而大部分时候我们希望能够让每篇博客文章都有一个独立的页面.
我第一个想到的方法是给每篇博客文章加一个view函数逻辑, 然后设置一个独立的url(我不知道语言比如PHP, 或者web框架rail等是如果解决的, 我是第一次仔细的学习web框架, 也没有前端开发经验), 但是这种方法耦合性太强, 而且用户不友好, 缺点非常多
Django给我们提供了一个方便的解决方法, 就是动态URL
现在修改my_blog/article/views.py代码:
# -*- coding: utf-8 -*-
from django.shortcuts import render
from django.http import HttpResponse
from article.models import Article
from datetime import datetime
from django.http import Http404
# Create your views here.
def home(request):
post_list = Article.objects.all() #获取全部的Article对象
return render(request, 'home.html', {'post_list' : post_list})
def detail(request, id):
try:
post = Article.objects.get(id=str(id))
except Article.DoesNotExist:
raise Http404
return render(request, 'post.html', {'post' : post})
因为id是每个博文的唯一标识, 所以这里使用id对数据库中的博文进行查找
在my_blog/my_blog/urls.py中修改url设置:
from django.conf.urls import patterns, include, url
from django.contrib import admin
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'my_blog.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),
url(r'^admin/', include(admin.site.urls)),
url(r'^$', 'article.views.home', name = 'home'),
url(r'^(?P<id>\d+)/$', 'article.views.detail', name='detail'),
)
然后在templates下建立一个用于显示单页博文的界面:
#post.html
{% extends "base.html" %}
{% block content %}
<div class="posts">
<section class="post">
<header class="post-header">
<h2 class="post-title">{{ post.title }}</h2>
<p class="post-meta">
Time: <a class="post-author" href="#">{{ post.date_time|date:"Y /m /d"}}</a> <a class="post-category post-category-js" href="#">{{ post.category }}</a>
</p>
</header>
<div class="post-description">
<p>
{{ post.content }}
</p>
</div>
</section>
</div><!-- /.blog-post -->
{% endblock %}
可以发现只需要对home.html进行简单的修改, 去掉循环就可以了.
修改home.html和base.html, 加入动态链接和主页, 归档, 专题和About Me按钮
<!--home.html-->
{% extends "base.html" %}
{% block content %}
<div class="posts">
{% for post in post_list %}
<section class="post">
<header class="post-header">
<h2 class="post-title"><a href="{% url "detail" id=post.id %}">{{ post.title }}</a></h2>
<p class="post-meta">
Time: <a class="post-author" href="#">{{ post.date_time |date:"Y /m /d"}}</a> <a class="post-category post-category-js" href="#">{{ post.category }}</a>
</p>
</header>
<div class="post-description">
<p>
{{ post.content }}
</p>
</div>
<a class="pure-button" href="{% url "detail" id=post.id %}">Read More >>> </a>
</section>
{% endfor %}
</div><!-- /.blog-post -->
{% endblock %}
<!--base.html-->
<!doctype html>

其中主要改动
- 添加了几个导航按钮, 方便以后添加功能(暂时不添加登陆功能)
- 添加read more按钮
- 在博客文章的增加一个链接, 链接的href属性为`{% url "detail" id=post.id %}`, 当点击这个文章题目时, 会将对应的数据库对
象的id传入的url中, 类似于url传参, 不记得的同学可以重新回到前几页翻一下. 这里将数据库对象唯一的id传送给url设置, url
取出这个id给对应的view中的函数逻辑当做参数. 这样这个id就传入对应的参数中被使用
比如: 点击到的博客文章标题的对象对应的id=2, 这个id被传送到name=detail的url中, '^(?P<id>\d+)/$'正则表达式匹配后>取出id, 然后将id传送到article.views.detail作为函数参数, 然后通过get方法获取对应的数据库对象, 然后对对应的模板进行渲染, 发送到浏览器中..
此时重新运行服务器, 然后在浏览器中输入http://127.0.0.1:8000/点击对应的博客文章题目, 可以成功的跳转到一个独立的页面中
