DAY 61 django16
1 首页样式(不用太关注)
2 开启meida的访问
-setting中配置MEDIA_ROOT=os.path.join(BASE_DIR,'media')
-FileField(upload_to='avatar/'),以后上传的头像都放在media下的avatar文件夹下
-re_path('^media/(?P<path>.*?)$', serve,kwargs={'document_root':settings.MEDIA_ROOT}),
-域+'media/avatar/a.jpg'
3 个人站点路由设计
0 伪静态
1 为了搜索引擎优化,动态页面做成伪静态
https://www.cnblogs.com/Zh1z3ven/p/14624772.html\
2 xx.html结尾的网页,权重高, p/14624772 p/14624772.php p/14624772.jsp 权重低
3 百度是个大爬虫,一刻不停的在互联网上爬取页面----》爬完存到自己的库中---》你们百度搜索---》去百度的库中搜---》返回你看到
4 谷歌需要FQ
1 左侧查询和个人主页路由整合
路由整合
re_path('^(?P<username>\w+)/(?P<condition>category|tag|archive)/(?P<params>.*).html$', views.personal_site),
视图函数
def personal_site(request, username, **kwargs):
user = models.UserInfo.objects.filter(username=username).first()
if user:
article_list = user.blog.article_set.all()
if kwargs:
condition = kwargs.get('condition')
params = kwargs.get('params')
if condition == 'category':
article_list = article_list.filter(category_id=params)
elif condition == 'tag':
article_list = article_list.filter(tag__id=params) #跨表了
elif condition == 'archive':
param_year, param_month = params.split('/')
article_list = article_list.filter(create_time__year=param_year, create_time__month=param_month)
return render(request, 'site.html', locals())
else:
return render(request, '404.html')
2 左侧标签,分类,归档写成inclusion_tag
left.py
from django import template
register = template.Library()
from blog import models
from django.db.models.functions import TruncMonth
from django.db.models import Count
left.html
<div>
<div class="panel panel-success">
<div class="panel-heading">
<h3 class="panel-title">我的标签</h3>
</div>
<div class="panel-body">
{% for tag in tag_list %}
<p><a href="/{{ username }}/tag/{{ tag.2 }}.html">{{ tag.1 }}({{ tag.0 }})</a></p>
{% endfor %}
</div>
</div>
<div class="panel panel-info">
<div class="panel-heading">
<h3 class="panel-title">我的分类</h3>
</div>
<div class="panel-body">
{% for category in category_list %}
<p>
<a href="/{{ username }}/category/{{ category.id }}.html">{{ category.name }}({{ category.count }})</a>
</p>
{% endfor %}
</div>
</div>
<div class="panel panel-info">
<div class="panel-heading">
<h3 class="panel-title">随笔档案</h3>
</div>
<div class="panel-body">
{% for month in month_list %}
<p>
<a href="/{{ username }}/archive/{{ month.0|date:'Y/m' }}.html">{{ month.0|date:'Y年m月' }}({{ month.1 }})</a>
</p>
{% endfor %}
</div>
</div>
</div>
使用
{% load left %}
{% left_inclusion_tag username %}
