python manage.py startapp userapp
python manage.py startapp blogapp
配置数据库
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'django_blog_db',
'USER': 'root',
'PASSWORD': 'wwy123',
'HOST': '127.0.0.1',

}
}
创建数据库(执行迁移文件)
python manage.py migrate
创建超级管理员
python manage.py createsuperuser
四、创建数据模型

from django.contrib.auth.models import AbstractUser
class BlogUser(AbstractUser):
nikename = models.CharField('昵称', max_length=20, default='')
提示：需要在settings配置文件中设置:AUTH_USER_MODEL = 'users.BlogUser'
EMAIL(邮箱验证数据模型)
class EmailVerifyRecord(models.Model):
code = models.CharField(verbose_name='验证码', max_length=50,default='')
email = models.EmailField(max_length=50, verbose_name="邮箱")
send_type = models.CharField(verbose_name="验证码类型", choices=(("register",u"注册"),("forget","找回密码"), ("update_email","修改邮箱")), max_length=30)
send_time = models.DateTimeField(verbose_name="发送时间", default=datetime.now)
class Meta:
verbose_name = "邮箱验证码"
# 复数
verbose_name_plural = verbose_name
def __str__(self):
return '{0}({1})'.format(self.code, self.email)
BLOGAPP
Banner(轮播图模型)
class Banner(models.Model):
title = models.CharField('标题', max_length=50)
cover = models.ImageField('轮播图', upload_to='static/images/banner')
link_url = models.URLField('图片链接', max_length=100)
idx = models.IntegerField('索引')
is_active = models.BooleanField('是否是active', default=False)
def __str__(self):
return self.title
class Meta:
verbose_name = '轮播图'
verbose_name_plural = '轮播图'
Category(博客分类模型)
class BlogCategory(models.Model):
name = models.CharField('分类名称', max_length=20, default='')
class Meta:
verbose_name = '博客分类'
verbose_name_plural = '博客分类'
def __str__(self):
return self.name
Tags(标签模型)
class Tags(models.Model):
name = models.CharField('标签名称', max_length=20, default='')
class Meta:
verbose_name = '标签'
verbose_name_plural = '标签'
def __str__(self):
return self.name

def __str__(self):
return self.title
class Meta:
verbose_name = '博客'
verbose_name_plural = '博客'

class Comment(models.Model):
post = models.ForeignKey(Post, verbose_name='博客')
user = models.ForeignKey(BlogUser, verbose_name='作者')
pub_date = models.DateTimeField('发布时间')
content = models.TextField('内容')
def __str__(self):
return self.content
class Meta:
verbose_name = '评论'
verbose_name_plural = '评论'

'DIRS': [os.path.join(BASE_DIR, 'templates')],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [

'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]

STATIC_URL = '/static/'
STATICFILES_DIRS = (
os.path.join(BASE_DIR, "static"),
)
