Django 1.9 开发web项目

时间：2015-12-25 06:38:36 收藏：0 阅读：6205

Python Version: 2.7.10
Django Version: 1.9
REST framework 3.3.2

创建项目:
django-admin startproject TestWeb

切换到项目中创建应用：

django-admin startapp app01

修改配置文件settings.py,添加你的应用app01和rest_framework

    INSTALLED_APPS = [
    ‘django.contrib.admin‘,
    ‘django.contrib.auth‘,
    ‘django.contrib.contenttypes‘,
    ‘django.contrib.sessions‘,
    ‘django.contrib.messages‘,
    ‘django.contrib.staticfiles‘,
    ‘app01‘
    ‘rest_framework‘,
    ]


app01文件夹下创建templates文件夹放入index.html模板文件

告诉你的应用模板文件路径，修改settings.py

TEMPLATE_DIRS=os.path.join(os.path.dirname(__file__),‘templates‘)

最新版1.9已无需配置默认会到应用的templates文件夹下寻找

    TEMPLATES = [
    {
        ‘BACKEND‘: ‘django.template.backends.django.DjangoTemplates‘,
        ‘DIRS‘: [],
        ‘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urls.py文件

    urlpatterns = [
    url(r‘^admin/‘, admin.site.urls),
    url(r‘^$‘, index),
    ]



启动你的应用

python manage.py runserver 8080

后台管理
数据库配置默认是sqlite,mysql的配置如下

    DATABASES = {
    ‘default‘: {
        ‘ENGINE‘: ‘django.db.backends.mysql‘,
        ‘USER‘:‘root‘,
        ‘PASSWORD‘:‘‘,
        ‘NAME‘:‘test‘,
        ‘HOST‘:‘localhost‘,
        #‘ENGINE‘: ‘django.db.backends.sqlite3‘,
        #‘NAME‘: os.path.join(BASE_DIR, ‘db.sqlite3‘),
    }
    }

localhost:8080/admin/登录报no such table: auth_user错误

运行python manage.py syncdb即可自动创建所需表

注意：Django 1.7.1及以上的版本python manage.py syncdb失效需要用以下命令

python manage.py makemigrations

python manage.py migrate

创建模型,修改models.py


    from __future__ import unicode_literals

    from django.db import models

    # Create your models here.
    class Mysite(models.Model):
        title=models.CharField(max_length=100)
        url=models.URLField()
        author=models.CharField(max_length=100)
        num=models.IntegerField()

        def __unicode__(self):
            return self.title

        class Meta:             #查询时会以num排序
            ordering= [‘num‘]


python manage.py shell 进入交互式数据查询

from app01.models import *

m=Mysite(title=‘django‘,num=2)

m.save()

m=Mysite.objects.all()

m[0].title

m=Mysite.objects.get(num=2)

m=Mysite(title=‘django‘,num=3)

m.save()

m=Mysite(title=‘django‘,num=9)

m.save()

m=Mysite.objects.all().order_by(‘num‘)#升序

m=Mysite.objects.all().order_by(‘-num‘)#降序

m.delete()

m=Mysite.objects.all()[0:2]

管理界面管理你的模型admin.py

    from django.contrib import admin
    from app01.models import *

    # Register your models here.
    admin.site.register(Mysite)

使用表单出现CSRF verification failed. Request aborted.错误

urls.py配置

    from django.conf.urls import url
    from django.contrib import admin
    from app01.views import *
    urlpatterns = [
    url(r‘^admin/‘, admin.site.urls),
        url(r‘^$‘, index),
        url(r‘^hello/$‘, hello),
    ]

静态资源文件配置

STATIC_URL = ‘/static/‘

STATICFILES_DIRS=(
   ‘D:/TestWeb/static‘,

)
