2.项目详情

2.1 数据库设计

核心代码：

1.继承AbstractUser 2.中介模型 3.联合惟一

 

 

from django.db import models ​ # Create your models here.
​ ​ from django.contrib.auth.models import AbstractUser ​ ​ class UserInfo(AbstractUser): """ 用户信息 """ nid = models.AutoField(primary_key=True) telephone = models.CharField(max_length=11, null=True, unique=True) avatar = models.FileField(upload_to='avatars/', default="avatars/default.png") create_time = models.DateTimeField(verbose_name='建立时间', auto_now_add=True) ​ blog = models.OneToOneField(to='Blog', to_field='nid', null=True, on_delete=models.CASCADE) ​ def __str__(self): return self.username ​ ​ class Blog(models.Model): """ 博客信息 """ nid = models.AutoField(primary_key=True) title = models.CharField(verbose_name='我的博客标题', max_length=64) site_name = models.CharField(verbose_name='站点名称', max_length=64) theme = models.CharField(verbose_name='博客主题', max_length=32) ​ def __str__(self): return self.title ​ ​ class Category(models.Model): """ 博主我的文章分类表 """ nid = models.AutoField(primary_key=True) title = models.CharField(verbose_name='分类标题', max_length=32) blog = models.ForeignKey(verbose_name='所属博客', to='Blog', to_field='nid', on_delete=models.CASCADE) ​ def __str__(self): return self.title ​ ​ class Tag(models.Model): nid = models.AutoField(primary_key=True) title = models.CharField(verbose_name='标签名称', max_length=32) blog = models.ForeignKey(verbose_name='所属博客', to='Blog', to_field='nid', on_delete=models.CASCADE) ​ def __str__(self): return self.title ​ ​ class Article(models.Model): nid = models.AutoField(primary_key=True) title = models.CharField(max_length=50, verbose_name='文章标题') desc = models.CharField(max_length=255, verbose_name='文章描述') create_time = models.DateTimeField(verbose_name='建立时间', auto_now_add=True) content = models.TextField() ​ comment_count = models.IntegerField(default=0) up_count = models.IntegerField(default=0) down_count = models.IntegerField(default=0) ​ user = models.ForeignKey(verbose_name='做者', to='UserInfo', to_field='nid', on_delete=models.CASCADE) category = models.ForeignKey(to='Category', to_field='nid', null=True, on_delete=models.CASCADE) tags = models.ManyToManyField( to="Tag", through='Article2Tag', through_fields=('article', 'tag'), ) ​ def __str__(self): return self.title ​ ​ class Article2Tag(models.Model): nid = models.AutoField(primary_key=True) article = models.ForeignKey(verbose_name='文章', to="Article", to_field='nid', on_delete=models.CASCADE) tag = models.ForeignKey(verbose_name='标签', to="Tag", to_field='nid', on_delete=models.CASCADE) ​ class Meta: unique_together = [ ('article', 'tag'), ] ​ def __str__(self): v = self.article.title + "---" + self.tag.title return v ​ ​ class ArticleUpDown(models.Model): """ 点赞表 """ ​ nid = models.AutoField(primary_key=True) user = models.ForeignKey('UserInfo', null=True, on_delete=models.CASCADE) article = models.ForeignKey("Article", null=True, on_delete=models.CASCADE) is_up = models.BooleanField(default=True) ​ class Meta: unique_together = [ ('article', 'user'), ] ​ ​ class Comment(models.Model): """ ​ 评论表 ​ """ nid = models.AutoField(primary_key=True) article = models.ForeignKey(verbose_name='评论文章', to='Article', to_field='nid', on_delete=models.CASCADE) user = models.ForeignKey(verbose_name='评论者', to='UserInfo', to_field='nid', on_delete=models.CASCADE) content = models.CharField(verbose_name='评论内容', max_length=255) create_time = models.DateTimeField(verbose_name='建立时间', auto_now_add=True) parent_comment = models.ForeignKey('self', null=True, on_delete=models.CASCADE) ​ def __str__(self): return self.content ​

2.2 站点管理

核心代码：

from django.contrib import admin ​ # Register your models here.
from blog import models ​ admin.site.register(models.UserInfo) admin.site.register(models.Article) admin.site.register(models.Article2Tag) admin.site.register(models.ArticleUpDown) admin.site.register(models.Blog) admin.site.register(models.Category) admin.site.register(models.Comment) admin.site.register(models.Tag)

2.3 注册

核心代码：

1.form组件 1.form组件 class RegForm(forms.Form):pass 局部钩子 全局钩子 ​ 2.上传头像 avatar 图像预览 var reader = new FileReader(); 上传文件 formdata = new FormData(); ​ 3.用户文件配置 avatar = models.FileField(upload_to='avatars/', default='avatars/default.png') MEDIA_ROOT = os.path.join(BASE_DIR, 'blog', 'media') MEDIA_URL = '/media/' re_path(r'media/(?P<path>.*)$',serve,{'document_root':settings.MEDIA_ROOT})

 

 

2.4 登陆

核心代码：

1.验证码 随机生成5个字符，0-9 a-z A-Z ​ pip install pillow from PIL import Image, ImageDraw, ImageFont image = Image.new() ​ 在内存中生成图片直接返回 from io import BytesIO f = BytesIO() ​ 2.request.session['valid_str'] = valid_str 存在session中，为了以后登陆，验证是否经过 ​ 3.验证码点击刷新： $('#valid_img').click(function () { $(this)[0].src += '?' }); ​ 4.认证组件 valid_str = request.session.get('valid_str') if valid_str.upper() == valid_code.upper(): user = auth.authenticate(username = user, password = pwd) if user: auth.login(request, user)

 

2.5 网站首页

核心代码：

1.bootstrap搭建页面 ​ 2.导航条 登陆： username / 注销 未登陆： 登陆 / 注册 ​ 3.for循环 {% for article in article_list %} {% endfor %}

 

网页底部分页器：

2.6 我的站点

1.文章列表，分类列表，标签列表，日期归档列表 文章列表： /blog/egon/ 分类列表： /blog/egon/cate/python 标签列表： /blog/egon/tag/生活 日期归档列表： /blog/egon/archive/2018-06 ​ 2.模板继承 {% extends 'base.html' %} ​ {% block content %} {% endblock content%}} ​ 3.自定义标签 /blog/templatetags/my_tag.py ​ @register.inclusion_tag('menu.html') def get_menu(username): ... return {} # 去渲染 menu.html
​ 4.分组查询 .annotate() / extra()应用 多表分组 tag_list = Tag.objects.filter(blog=blog).annotate( count = Count('article')).values_list('title', 'count') ​ 单表分组 / DATE_FORMAT() / extra() date_list = Article.objects.filter(user=user).extra( select={"create_ym": "DATE_FORMAT(create_time,'%%Y-%%m')"}).values('create_ym').annotate( c = Count('nid')).values_list('create_ym', 'c') ​ 5. 时间、区域配置 TIME_ZONE = 'Asia/Shanghai' USE_TZ = False

 

2.7 文章详情

核心代码：

1.模板继承 article = Article.objects.filter(pk=article_id).first() {% extends 'base.html' %} {% block content %} ... {{ article.articledetail.content|safe }} {% endblock content %}

 

 2.8 后台管理

核心代码：

1.支持文章编辑 2.支持富文本编辑器（支持渲染已有文章） 3.支持删除文章 4.防止Xss攻击（基于BS4） # 防止xss攻击,过滤script标签
        soup = BeautifulSoup(content, "html.parser") for tag in soup.find_all(): ​ if tag.name == "script": tag.decompose()

 

 

2.9 批量创建测试数据

核心代码：

1.定制创建测试数据 2.初始化获得100条用户信息，以及为100个客户分别添加文章、博客的详细信息

 

def supreme(request): """ 这是数据初始化视图，将会生成99条测试数据，用户名为管理员输入的字符后，加1_99. 密码为管理员填入的密码 :param request: :return: """ tag_title = ['BASIC', 'C', 'C++', 'PASCAL', 'FORTRAN', 'LISP', 'Prolog', 'CLIPS', 'OpenCyc', 'Fazzy', 'Python', 'PHP', 'Ruby', 'Lua'] category_titles = ['非技术区', '软件测试', '代码与软件发布', '计算机图形学', '游戏开发', '程序人生', '求职面试', '读书区', '转载区', 'Windows', '翻译区', '开源研究', 'Flex'] userlist = [] bolglist = [] article_list = [] tag_list = [] cat_list = [] article2tag_list = [] ​ if request.is_ajax(): ​ form = UserForm(request.POST) response = {'user': None, 'msg': None} if form.is_valid(): ​ response['user'] = form.cleaned_data.get('user') # 生成一条用户记录
            user = form.cleaned_data.get('user') ​ pwd = form.cleaned_data.get('pwd') email = form.cleaned_data.get('email') avatar_obj = request.FILES.get('avatar') extra = {} if avatar_obj: extra['avatar'] = avatar_obj with transaction.atomic(): for i in range(1, 100): Blog.objects.create(title='blog%s' % i) ​ UserInfo.objects.create_user(username=user + str(i), password=pwd, email=email, **extra) ​ UserInfo.objects.filter(username=user + str(i)).update(blog_id=i) ​ for title in tag_title: tag_list.append(Tag(title=title, blog_id=i)) ​ for cat in category_titles: cat_list.append(Category(title=cat, blog_id=i)) import random for c in range(1, 7): with open('/home/hyc/PycharmProjects/cnblog/static/superme/%s.txt' % c, 'r', encoding='utf-8') as f: content = f.read() ​ soup = BeautifulSoup(content, "html.parser") for tag in soup.find_all(): if tag.name == "script": tag.decompose() desc = soup.text[0:150] + "..." c_id = 13 * (i - 1) + random.randrange(1, 9) ​ article_list.append( Article(desc=desc, title='article%s' % c, content=content, user_id=i, category_id=c_id)) ​ Category.objects.bulk_create(cat_list) Tag.objects.bulk_create(tag_list) Article.objects.bulk_create(article_list) ​ else: response['msg'] = form.errors return JsonResponse(response) ​ my_from = UserForm ​ return render(request, 'supreme.html', {'from': my_from})
