python 全栈开发，Day80(博客系统分析,博客主页展示)
2024-10-15 17:31:39
一、博客系统分析
数据库的构建
首先，我们分析一个博客系统的功能：
- 一个博客可以有多个标签（多对多）
- 一个博客可以有多条评论(一对多）
- 一个博客只可以有一个类别（多对一）
接下来，我们分析关系的属性：
博客：标题，作者，内容，发布时间，分类（外键），标签（多对多）等
标签：标签名
类别：分类名
评论：作者，博客（外键），邮箱，内容，发布时间等。
有8张表，表关系如下：
图中箭头开始的英文字母表示关联字段
按照箭头方向查询，表示正向查询，否则为反向查询
新建项目cnblog，应用名为blog
修改models.py，必须导入模块
from django.contrib.auth.models import AbstractUser
因为有一个表userinfo需要继承它。django自带的auth_user表也是继承AbstractUser
表模型如下：
from django.db import models # Create your models here. 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='创建时间', 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='个人博客标题', 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):
"""
博主个人文章分类表
"""
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='创建时间', 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='作者', 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参数可以指定用作中介的中间模型
through='Article2Tag',
) 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:
#组合唯一约束
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:
# 组合唯一约束
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='创建时间', auto_now_add=True)
parent_comment = models.ForeignKey('Comment', null=True, on_delete=models.CASCADE) def __str__(self):
return self.content
相关参数解释：
through 表示orm，不要创建关系表。而制定一个表，这个表自己来创建！为什么呢？因为orm创建多对多关系表时，只有3个字段。那么需要关系表需要扩充字段时，就不行了！
所以设置through 字段，是为了方便添加额外的字段。使用through，那么这个表，称之为中间模型。
在Comment模型表中，有一个字段parent_comment。它关联的是本身表中的主键nid，它是一个父级评论id，用来展示谁评论谁！to='Comment'等同于to='self'
修改settings.py配置文件，覆盖默认的User模型。最后一行添加，否则执行创建表命令时会报错！
AUTH_USER_MODEL="blog.UserInfo"
Django允许你通过修改setting.py文件中的 AUTH_USER_MODEL 设置覆盖默认的User模型，其值引用一个自定义的模型。
bolg，是应用名。
使用下面2个命令，生成表
python manage.py makemigrations
python manage.py migrate
生成的表如下：
注意：django自带的auth_user表没有了，取而代之的是blog_userinfo表。
查看表字段
它在auth_user表的基础上，增加了5个字段！
登录验证
添加超级用户，密码必须是8位或者以上！
python manage.py createsuperuser
效果如下：
再创建2个用户，zhang和lisi。用来测试多个用户登录！
lisi用户
修改urls.py，增加路径
from blog import views
urlpatterns = [
path('admin/', admin.site.urls),
path('index/', views.index),
path('login/', views.login),
]
修改views.py，增加视图函数
from django.shortcuts import render,HttpResponse,redirect
from django.contrib import auth
from blog.models import Article,UserInfo # Create your views here.
def login(request): if request.method=="POST":
user=request.POST.get("user")
pwd=request.POST.get("pwd")
# 用户验证成功,返回user对象,否则返回None
user=auth.authenticate(username=user,password=pwd)
if user:
# 登录,注册session
# 全局变量 request.user=当前登陆对象(session中)
auth.login(request,user)
return redirect("/index/") return render(request,"login.html") def index(request):
return render(request,"index.html")
修改login.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="" method="post">
{% csrf_token %}
<lable>用户名</lable><input type="text" name="user">
<lable>密码</lable><input type="password" name="pwd">
<input type="submit">
</form>
</body>
</html>
修改index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h3>INDEX</h3>
</body>
</html>
访问登录页面
跳转到首页
首页修饰
修改settings.py，设置静态文件目录。最后一行添加：
STATICFILES_DIRS=[
os.path.join(BASE_DIR,"static")
]
下载bootsrtap，将压缩的包内容放到satic目录
img和js是新建的
目录如下：
修改urls.py，增加路径
urlpatterns = [
path('admin/', admin.site.urls),
path('login/', views.login),
path('index/', views.index),
path('logout/', views.logout),
path('', views.index),
]
修改views.py，增加注销
def logout(request): # 注销
auth.logout(request)
return redirect("/index/")
修改index.html

访问xiao的个人站点，效果如下：
这个时候发现，左上角没有显示博客标题。那是因为用户认证表的blog_id字段默认为空，需要在admin后台绑定一下
登录到后台，点击用户表，点击指定的用户xiao
拉到最下面，绑定blog，点击保存
再次刷新个人站点，发现出来了！
作业：
查询当前站点每一个分类的名称以及对应的文章数
查询当前站点每一个标签的名称以及对应的文章数
