三 創(chuàng)建項(xiàng)目
1 進(jìn)入虛擬環(huán)境創(chuàng)建項(xiàng)目

django-admin startproject django_blog

2 進(jìn)入項(xiàng)目創(chuàng)建應(yīng)用

python manage.py startapp userapp
python manage.py startapp blogapp

3 在settings中配置數(shù)據(jù)庫(kù)

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'blog_db',
'USER': 'root',
'PASSWORD': '1',
'HOST': '127.0.0.1',
'PORT': '3306',
      }
}

4 執(zhí)行遷移文件

python manage.py migrate

5 創(chuàng)建超級(jí)管理員

python manage.py createsuperuser

四 創(chuàng)建數(shù)據(jù)模型
userapp

USER(用戶模型)

from django.contrib.auth.models import AbstractUser

class BlogUser(AbstractUser):
nikename = models.CharField('昵稱', max_length=20, default='')

注:需要在settings配置文件中設(shè)置： AUTH_USER_MODEL = 'users.BlogUser'
blogapp
Banner(輪播圖模型)

class Banner(models.Model):
    title = models.CharField('標(biāo)題'程腹，max_length = 50)
    cover = models.ImageField('輪播圖',    upload_to='static/images/banner')
    link_url = models.URLField('圖片鏈接', 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 = '輪播圖'
        verbose_name_plural = '輪播圖'

Category(博客分類模型)

class BlogCategory(models.Model):
    name = models.CharField('分類名稱', max_length=20, default='')
    class Meta:
        verbose_name = '博客分類'
        verbose_name_plural = '博客分類'

    def __str__(self):
    return self.name

Tags(標(biāo)簽?zāi)Ｐ?

class Tags(models.Model):
    name = models.CharField('標(biāo)簽名稱', max_length=20, default='')
    class Meta:
        verbose_name = '標(biāo)簽'
        verbose_name_plural = '標(biāo)簽'

    def __str__(self):
        return self.name

Blog(博客模型)

class Post(models.Model):
    user = models.ForeignKey(BlogUser, verbose_name='作者')
    category = models.ForeignKey(BlogCategory, verbose_name='博客分類', default=None)
    tags = models.ManyToManyField(Tags, verbose_name='標(biāo)簽')
    title = models.CharField('標(biāo)題', max_length=50)
    content = models.TextField('內(nèi)容')
    pub_date = models.DateTimeField('發(fā)布日期', default=datetime.now)
    cover = models.ImageField('博客封面',  upload_to='static/images/post', default=None)
    views = models.IntegerField('瀏覽數(shù)', default=0)
    recommend = models.BooleanField('推薦博客', default=False)

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

Comment(評(píng)論模型)

class Comment(models.Model):
    post = models.ForeignKey(Post, verbose_name='博客')
    user = models.ForeignKey(BlogUser, verbose_name='作者')
    pub_date = models.DateTimeField('發(fā)布時(shí)間')
    content = models.TextField('內(nèi)容')

    def __str__(self):
        return self.content
    class Meta:
        verbose_name = '評(píng)論'
        verbose_name_plural = '評(píng)論'

FriendlyLink(友情鏈接模型)

        verbose_name_plural = '友情鏈接'

五敌卓、實(shí)現(xiàn)首頁(yè)頁(yè)面模板創(chuàng)建模板文件夾
創(chuàng)建模板文件templates,并在settings.py中設(shè)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',
],
},
},
]

配置靜態(tài)文件路徑

STATIC_URL = '/static/'

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

六奖磁、創(chuàng)建首頁(yè)路由
創(chuàng)建視圖函數(shù)

def index(request):
    return render(request, 'index.html', {})

• 配置url

url(r'^index/$', index, name='index' )

七、實(shí)現(xiàn)幻燈片功能(Banner)
注冊(cè)模型

from blogs.models import Banner
admin.site.register(Banner)

編寫(xiě)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 開(kāi)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">
