二、开发环境搭建
使用virtualenv 和 virtualenwrapper
MySQL 5.7
sudo apt install mysql-server mysql-client
安装mysql驱动
pip install pymysql
安装Django
pip install django==1.11
三、创建项目
创建项目和应用
创建项目
django-admin startproject django-blog
创建应用
python manage.py startapp userapppython manage.py startapp blogapp
配置数据库
在settings中配置数据库
DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'django_blog_db', 'USER': 'root', 'PASSWORD': 'wwy123', 'HOST': '127.0.0.1', 'PORT': '3306',
}
}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
USERAPP
USER(用户模型)
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.nameTags(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.nameBlog(博客模型)
class Post(models.Model):
user = models.ForeignKey(BlogUser, verbose_name='作者')
category = models.ForeignKey(BlogCategory, verbose_name='博客分类', default=None)
tags = models.ManyToManyField(Tags, verbose_name='标签')
title = models.CharField('标题', max_length=50)
content = models.TextField('内容')
pub_date = models.DateTimeField('发布日期', default=datetime.now)
cover = models.ImageField('博客封面', upload_to='static/images/post', default=None)
views = models.IntegerField('浏览数', default=0)
recommend = models.BooleanField('推荐博客', default=False)
def __str__(self):
return self.title
class Meta:
verbose_name = '博客'
verbose_name_plural = '博客'Comment(评论模型)
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'FriendlyLink(友情链接模型)
class FriendlyLink(models.Model):
title = models.CharField('标题', max_length=50)
link = models.URLField('链接', max_length=50, default='')
def __str__(self):
return self.title
class Meta:
verbose_name = '友情链接'
verbose_name_plural = '友情链接'五、实现首页页面模板
创建模板文件夹
创建模板文件templates,并在settings.py中设置
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates')],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]配置静态文件路径
STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR, "static"), )
六、创建首页路由
创建视图函数
def index(request):
return render(request, 'index.html', {})配置url
url(r'^$', index, name='index' )
修改模板CSS JS等静态文件的路径
七、实现幻灯片功能(Banner)
注册模型
from blogs.models import Banner admin.site.register(Banner)
编写views
from .models import Banner
def index(request):
banner_list = Banner.objects.all()
ctx = {
'banner_list': banner_list,
}
return render(request, 'index.html', ctx)模板
<!-- banner 开始 -->
<div id="focusslide" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
{% for banner in banner_list %}
{% if banner.is_active %}
<li data-target="#focusslide" data-slide-to="{{banner.idx}}" class="active"></li>
{% else %}
<li data-target="#focusslide" data-slide-to="{{banner.idx}}"></li>
{% endif %}
{% endfor %}
</ol>
<div class="carousel-inner" role="listbox">
{% for banner in banner_list %}
{% if banner.is_active %}
<div class="item active">
<a href="{{banner.link_url}}" target="_blank" title="{{banner.title}}" >
<img src="{{banner.cover}}" alt="{{banner.title}}" class="img-responsive"></a>
</div>
{% else %}
<div class="item">
<a href="{{banner.link_url}}" target="_blank" title="{{banner.title}}" >
<img src="{{banner.cover}}" alt="{{banner.title}}" class="img-responsive"></a>
</div>
{% endif %}
{% endfor %}
</div>
<a class="left carousel-control" href="#focusslide" role="button" data-slide="prev" rel="nofollow">
<span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
<span class="sr-only">上一个</span> </a>
<a class="right carousel-control" href="#focusslide" role="button" data-slide="next" rel="nofollow">
<span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
<span class="sr-only">下一个</span> </a>
</div>
<!-- banner 结束 -->八、实现博客推荐

'recommend_list': recommend_list,
'post_list': post_list,
}
return render(request, 'index.html', ctx)模板
<!-- 最新发布的博客开始 -->
{% for post in post_list%}
<article class="excerpt excerpt-1" style="">
<a class="focus" href="/blog/{{post.id}}/" title="{{post.title}}" target="_blank" ><img class="thumb" data-original="/{{post.cover}}" src="/{{post.cover}}" alt="{{post.title}}" style="display: inline;"></a>
