二.ORM模型设计

需要创建的表

用户信息表-----UserInfo
个人站点表-----Blog
分类表--------Category
标签表--------Tag
文章表--------Article 文章与标签的关联表---ArticleToTag 点赞点踩表-----UpAndDown 文章评论表-----Commit

表与表之间的关联关系

UserInfo --- 一对一 ---Blog
Blog --- 一对多 --- Category Blog --- 一对多 --- Tag Article --- 一对多 --- UserInfo Article --- 一对多 --- Category Article --- 多对多 --- Tag UpAndDown --- 一对多 --- UserInfo UpAndDown --- 一对多 --- Article Commit --- 一对多 --- UserInfo Commit --- 一对多 --- Article 子评论关联Commit自身

三.配置文件

配置需要使用的数据库

DATABASES = {'default': {'ENGINE': 'django.db.backends.mysql','NAME': 'day86_BBS', 'PORT': 3306, 'HOST': '127.0.0.1', 'USER': 'root', 'PASSWORD': '970420', } }

扩展默认的auth_user表的配置

AUTH_USER_MODEL = 'app名.表名'

根路由配置

STATIC_URL= '/login/'

静态文件配置

STATICFILES_DIRS = [os.path.join(BASE_DIR,'static')
]

四.创建表模型

from django.db import models
from django.contrib.auth.models import AbstractUser # Create your models here. class Blog(models.Model): ''' 个人站点表 ''' id = models.AutoField(primary_key=True) title = models.CharField(max_length=64, verbose_name='站点标题') site_name = models.CharField(max_length=64, verbose_name='站点名称') theme = models.CharField(max_length=255, verbose_name='站点样式') class UserInfo(AbstractUser): ''' 用户表 ''' phone = models.CharField(max_length=32, verbose_name='手机号', null=True) avatar = models.FileField(upload_to='avatar/', default='/avatar/default.png', verbose_name='用户头像', null=True) create_data = models.DateField(auto_now_add=True, verbose_name='创建时间') blog = models.OneToOneField(to='Blog') class Category(models.Model): ''' 文章类别表 ''' id = models.AutoField(primary_key=True) title = models.CharField(max_length=32, verbose_name='类别名') blog = models.ForeignKey(to=Blog, null=True) class Tag(models.Model): ''' 文章标签表 ''' id = models.AutoField(primary_key=True) title = models.CharField(max_length=32, verbose_name='标签名') blog = models.ForeignKey(to=Blog, null=True) class Article(models.Model): ''' 文章表 ''' id = models.AutoField(primary_key=True) title = models.CharField(max_length=64, verbose_name='文章标题') desc = models.CharField(max_length=255, verbose_name='摘要') create_time = models.DateTimeField(auto_now_add=True, verbose_name='发表时间') content = models.TextField(verbose_name='文章内容') # 关联关系 category = models.ForeignKey(to='Category', null=True) tag = models.ManyToManyField(to='Tag', through='ArticleToTag', through_fields=('article', 'tag')) blog = models.ForeignKey(to='Blog', null=True) class ArticleToTag(models.Model): ''' 手动创建的文章关联标签表 ''' id = models.AutoField(primary_key=True) article = models.ForeignKey(to='Article') tag = models.ForeignKey(to='Tag') class Commit(models.Model): ''' 评论表 ''' id = models.AutoField(primary_key=True) user = models.ForeignKey(to='UserInfo') article = models.ForeignKey(to='Article') content = models.CharField(max_length=255, verbose_name='评论内容') commit_time = models.DateTimeField(auto_now_add=True) # 自关联 # parent = models.ForeignKey(to='Commit',null=True) parent = models.ForeignKey(to='self', null=True) # 联合唯一,防止写脏数据 class Meta: unique_together = (('user', 'article'),) class UpAndDown(models.Model): ''' 点赞点踩表 ''' id = models.AutoField(primary_key=True) user = models.ForeignKey(to='UserInfo') article = models.ForeignKey(to='Article') is_up = models.BooleanField() class Meta: unique_together = (('user', 'article'),) 

五.生成5位随机验证码

from django.shortcuts import render, HttpResponse
from PIL import Image, ImageDraw, ImageFont import random from io import BytesIO # 生成随机颜色 def get_color(): return ( random.randint(0, 255), random.randint(0, 255), random.randint(0, 255) ) # 生成随机数 def get_number(n): res = '' for i in range(n): C = chr(random.randint(65, 90)) c = chr(random.randint(97, 122)) num = random.randint(0, 9) res += random.choice([C, c, str(num)]) return res def get_code(request): # 生成图片对象 img = Image.new('RGB', (174, 35), color=get_color()) # 生成画笔对象 img_draw = ImageDraw.Draw(img) # 生成字体对象,第一参数字体文件路径,第二个参数字体大小 font = ImageFont.truetype('static/font/ss.TTF', 25) # 获取随机文本内容 res = get_number(5) # print(res) # 使用画笔工具,对图片对象写入文本 # text方法第一个参数为文本在图片的坐标,第二个参数是文本内容,第三个参数是文本颜色,第四个参数是文本字体 img_draw.text((35, 0), res, get_color(), font) # 将随机文本内容保存到session res = res.lower() request.session['code_text'] = res # 在内存中生成一个空文件 f = BytesIO() # 将图片放入内存,存取快,且会自动清理 img.save(f, 'png') # 获得图片数据 data = f.getvalue() return HttpResponse(data)
