一.文章详情
路由url.py:
url(r‘^(?P<username>\w+)/article/(?P<pk>\d+)$‘, views.article_detail),
点击个人站点文章title即可关联到文章详情路由找到其视图函数
views.py:
def article_detail(request,username,pk): user = models.UserInfo.objects.filter(username=username).first() if not user: return render(request, ‘error.html‘) blog = user.blog category_ret=models.Category.objects.all().filter(blog=blog).annotate(cou=Count(‘article__nid‘)).values_list(‘title‘,‘cou‘,‘nid‘) tag_ret=models.Tag.objects.all().filter(blog=blog).annotate(cou=Count(‘article__nid‘)).values_list(‘title‘,‘cou‘,‘nid‘) year_ret=models.Article.objects.all().annotate(month=TruncMonth(‘create_time‘)).values(‘month‘).annotate(c=Count(‘nid‘)).values_list(‘month‘,‘c‘) article=models.Article.objects.filter(nid=pk).first() # commit_list=article.commit_set.all() 前台模板渲染也可获取评论列表 return render(request,‘article_detail.html‘,locals())
ps: 通过有名分组拿到用户名和文章id,找到该文章对象渲染到article_detail.html (用到了母版base.html)

点赞点踩视图函数: 开启事务,将点赞点踩表创建记录的同时,把文章表的点赞或点踩数也加一
import json from django.db.models import F def diggit(request): response={‘code‘:100,‘msg‘:None} #当前登陆用户id if request.user.is_authenticated(): user_id=request.user.nid is_up=request.POST.get(‘is_up‘) print(type(is_up)) print(is_up) is_up=json.loads(is_up) print(type(is_up)) print(is_up) article_id=request.POST.get(‘article_id‘) up_ret=models.UpAndDown.objects.filter(user_id=user_id,article_id=article_id).first() if up_ret: response[‘code‘] = 102 response[‘msg‘] = ‘您已经点过了‘ else: #事务性的操作 from django.db import transaction #开启事务 with transaction.atomic(): models.UpAndDown.objects.create(article_id=article_id,user_id=user_id,is_up=is_up) if is_up: #文章表点赞字段加一 models.Article.objects.filter(pk=article_id).update(up_num=F(‘up_num‘)+1) response[‘msg‘] = ‘点赞成功‘ else: models.Article.objects.filter(pk=article_id).update(down_num=F(‘down_num‘)+1) response[‘msg‘] = ‘点踩成功‘ else: response[‘code‘]=101 response[‘msg‘]=‘请先登陆‘ return JsonResponse(response,safe=False)

评论视图函数:开启事务,在评论表添加记录的同时,也在文章表添加评论数
def commit(request): response = {‘code‘: 100, ‘msg‘: None} # 当前登陆用户id if request.user.is_authenticated(): user_id = request.user.nid article_id = request.POST.get(‘article_id‘) content=request.POST.get(‘content‘) parent_id=request.POST.get(‘parent_id‘) # 事务性的操作 from django.db import transaction # 开启事务 with transaction.atomic(): ret=models.Commit.objects.create(article_id=article_id,content=content,user_id=user_id,parent_id=parent_id) models.Article.objects.filter(pk=article_id).update(comment_num=F(‘comment_num‘) + 1) response[‘username‘]=ret.user.username response[‘reply_content‘]=ret.content if parent_id: response[‘parent_name‘] = ret.parent.user.username response[‘msg‘] = ‘评论成功‘ else: response[‘code‘] = 101 response[‘msg‘] = ‘请先登陆‘ return JsonResponse(response, safe=False)
二.后台展示,添加文章
路由url.py:
# 后台管理首页 url(r‘^backend/‘, views.home_backend),
视图函数:
from django.contrib.auth.decorators import login_required @login_required(login_url=‘/login/‘) def home_backend(request): #查询该人的所有文章 ariticle_list=models.Article.objects.filter(blog=request.user.blog) return render(request,‘backend/home_backend.html‘,locals())
前端渲染母版backend_base.html:

添加文章路由:
# 添加文章 url(r‘^add_article/‘, views.add_article),
添加文章视图函数:(用bs4来解析html文档,删除script标签内容来防止xss
@login_required(login_url=‘/login/‘) def add_article(request): if request.method==‘GET‘: return render(request,‘backend/add_article.html‘) else: title=request.POST.get(‘title‘) text_content=request.POST.get(‘text_content‘) #通过bs4 处理xss攻击，html文档解析库 #pip3 install beautifulsoup4 from bs4 import BeautifulSoup soup=BeautifulSoup(text_content,‘html.parser‘) #查找所有的标签 tags=soup.find_all() for tag in tags: if tag.name==‘script‘: #从文档中删除该标签 tag.decompose() #soup.text 文档的内容，不包含标签 desc=soup.text[0:150] models.Article.objects.create(title=title,desc=desc,content=str(soup),blog=request.user.blog) return redirect(‘/backend/‘)
添加文章add_article.html(借助富文本编辑器):
{% extends ‘backend/backend_base.html‘ %}
{% block content %}
<div>
<p>添加文章</p>
<form action="/add_article/" method="post">
{% csrf_token %}
<div class="form-group">

</p>

<script charset="utf-8" src="/static/kindeditor/kindeditor-all.js"></script>
<script>
KindEditor.ready(function (K) {
window.editor = K.create(‘#editor_id‘, {

{#]#}
uploadJson: ‘/uploadimg/‘,
extraFileUploadParams: {
csrfmiddlewaretoken: ‘{{ csrf_token }}‘,
}
});
});
</script>
{% endblock %}
在富文本编辑器中上传图片,图片地址放在media/file下即可:
@login_required(login_url=‘/login/‘) def uploadimg(request): response={ "error" : 0, "url" : None } fil=request.FILES.get(‘imgFile‘) with open(‘media/file/‘+fil.name,‘wb‘) as f: for line in fil: f.write(line) response[‘url‘]=‘/media/file/‘+fil.name return JsonResponse(response)
