用django写一个博客项目

1.查询所有的文章，完成文章的展示列表页

（1）查询所有文章(views.py)

def showType(request):
    #types = Type.objects.all() #查询所有的数据
    #types = Type.objects.filter(label="小说",id = 3) #安装条件查询
    #types = Type.objects.filter(label="动画片").first() #安装条件查询，返回第一条，没有返回None
    #types = Type.objects.get(id = 18) #直接获取单条数据，没有报错,get查询的条件必须唯一，一般用id
    #通常排序安装时间排序
    #types = Type.objects.order_by("id") #排序 相当于all
    #types = Type.objects.order_by("-id") #排倒序
    #types = Type.objects.filter(label="小说").order_by("-id")
    types = Type.objects.filter()[:3].order_by() #限制条数
    return render_to_response("showType.html",locals())

（2）将数据返回前端

（3）前端调用循环渲染数据

newList.html

{% extends 'base.html'%}
{% block content %}
    <div class="dtxw box">
      {% if articles %}
          {% for article in articles %}
              <li>
            <div class="dttext f_l">
              <ul>
                <h2><a href="/new/{
   { article.id }}/">{
   { article.title }}</a></h2>
                <p>{
   { article.description }}</p>
                <span>{
   { article.time }}</span>
              </ul>
            </div>
            <div class="xwpic f_r"><a href="/new/{
   { article.id }}/"><img src="/static/{
   { article.picture }}"></a></div>
          </li>
          {% endfor %}
      {% else %}
          <p>抱歉，这家伙很懒什么都没有留下</p>
      {% endif %}
</div>
{% endblock %}

base.html

{% load static %}

2.根据列表页提供的id查询文章详情

（1）查询详情

views.py

（2）返回前端

new.html

核心代码

<div class="about_box">
  <h2 class="nh1"><span>您现在的位置是：<a href="/" target="_blank">网站首页</a>>><a href="#" target="_blank">信息浏览</a></span><b>个人简介</b></h2>
  <div class="f_box">
    <p class="a_title">{
   { article.title }}</p>
    <p class="p_title"></p>
    <p class="box_p"><span>发布时间：{
   { article.time }}</span><span>作者：{
   { article.author.name }}</span></p>
  </div>
  <ul class="about_content">
    <p> {
   { article.content }}</p>
    <p><img src="/static/{
   { article.picture }}"></p>
  </ul>
</div>
