Django 博客搭建

python django

项目与APP

[1] 项目创建
运行以下程序，用于在当前目录下创建项目my_blog

django-admin.py startproject my_blog

[2] 创建Django app

python manage.py startapp article

并在my_blog/my_blog/setting.py里面添加如下代码：

INSTALLED_APPS = [
...
'article', #这里填写的是APP的名称
]

[3] 运行程序

python manage.py runserver

Models

[1] 创建Models
在my_blog/article/modles.py下编写如下代码：

frmo django.db import modles
class Article(modles.Modle):
    title = modles.CharField(max_length = 100)
    category = modles.CharField(max_length = 50,blank = True)
    date_time = modles.DateTimeField(auto_now_add = True)
    content = modles.TextField(blank = True,null = True)
    def __unicode__(self):
        return self.title
    class Meta:
        ordering = ['-date_time']

[2] 同步数据库

python manage.py migrate
python manage.py makemigrations
python manage.py migrate

[3] 进入Django交互式shell

python manage.py shell

from article.models import Article
Article.objects.create(title = 'Hello World',category = 'Python',content = 'let us to make a simple dataBase opertion')
Article.objects.create(title = 'Learn Django Blog',category = 'Python',content = 'Django Blog 学习')
Article.objects.all()
Article.objects.get(id = 1)
first = Article.objects.get(id = 1)
first.title
first.content
first.date_time
first.content = 'Hello yudesong'
first.delete()
Article.objects.all()

Admin

[1] 创建超级用户

python manage.py createsuperuser

[2] 注册Modles
在my_blog/article/admin.py里面添如下代码，后刷新页面 http://127.0.0.1:8000/admin

from django.contrib import admin
from article.models import Article
# Register your models here.
admin.site.register(Article)

[3] 使用第三方插件
安装

pip install bootstrap-admin

配置
在my_blog/my_blog/setting.py中修改INSTALLED_APPS

INSTALLED_APPS = [
    'bootstrap_admin', #一定要放在'django.contrib.admin'前面
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'article',
]

View and URL

[1] 简单Django Views 和URL
在my_blog/article/views.py编写简单逻辑

from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
def home(request):
    return HttpResponse("Hello World,Django");

在my_blog/my_blog/urls.py编写url映射

from django.conf.urls import url,include
from django.contrib import admin
from article import views
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^$',views.home),
]

[2] Django Views 和URL更进一步
修改my_blog/article/views.py

from article.models import Article
def detail(request, my_args):
    post = Article.objects.all()[int(my_args)]
    str = ("title = %s, category = %s, date_time = %s, content = %s"
    % (post.title, post.category, post.date_time, post.content))
    return HttpResponse(str)

修改my_blog/my_blog/urls.py

url(r'^(\d+)/$', views.detail, name='detail'),

Templates

[1]在my_blog/article下添加文件夹templates并添加文件test.html

<!--在test.html文件夹下添加-->
<!DOCTYPE html>
<html>
<head>
    <title>Just test template</title>
    <style>
    body {
        background-color: red;
    }
    em {
        color: LightSeaGreen;
    }
    </style>
</head>
<body>
    <h1>Hello World!</h1>
    <strong>{{ current_time }}</strong>
</body>
</html>

[2]在my_blog/my_blog/setting.py设置templates的位置添加

TEMPLATE_DIRS = (os.path.join(BASE_DIR, 'templates').replace('\','/'),)

[3]在templates目录文件夹添加base.html

<!doctype html>
<html lang="en">
<head>
    <meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta name="description" content="A layout example that shows off a blog page with a list of posts.">
