url伪静态化，左侧侧边栏使用inclusion_tag模板化，文章页功能实现，前后端搭建，点赞点踩前后端实现👆

BBS 项目（五）

实现伪静态（人工智能版）

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')

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

@register.inclusion_tag('left.html')
def left_inclusion_tag(username):
    user=models.UserInfo.objects.filter(username=username).first()
    category_list = models.Category.objects.filter(blog=user.blog).annotate(count=Count('article')).values('count',
                                                                                                           'name', 'id')
    tag_list = models.Tag.objects.filter(blog=user.blog).annotate(count=Count('article')).values_list('count',
                                                                                                      'name', 'id')

    month_list = models.Article.objects.filter(blog=user.blog).annotate(month=TruncMonth('create_time')).values(
        'month').annotate(count=Count('id')).values_list('month', 'count')

    return {'username':username,'category_list':category_list,'tag_list':tag_list,'month_list':month_list}

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

这样哪里需要左侧样式直接cpoy就可以了

{% load left %}
{% left_inclusion_tag username %}
