运行命令mysql -uroot -p进入mysql
新建一个数据库mydatabase
在/mysite/mysite目录下 编辑settings.py文件：
默认数据库为sqlite：
DATABASES = {
‘default‘: {
‘ENGINE‘: ‘django.db.backends.sqlite3‘,
‘NAME‘: ‘mydatabase‘,
}
}
mysql数据库配置：
DATABASES = {
‘default‘: {
‘ENGINE‘: ‘django.db.backends.mysql‘,
‘NAME‘: ‘mydatabase‘,
‘USER‘: ‘root‘,
‘PASSWORD‘: ‘123‘,
‘HOST‘: ‘127.0.0.1‘,
‘PORT‘: ‘3306‘,
}
}
启动django：python manage.py runserver
在新的shell运行：python manage.py runserver
from django.db import connection
cursor = connection.cursor()
没有报错 表示配置完成
建立新的一个app 运行命令：
python manage.py startapp myapp
进去myapp目录 编辑 models.py文件
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.db import models
# Create your models here.
class Publisher(models.Model):
name = models.CharField(max_length=30)
address = models.CharField(max_length=50)
city = models.CharField(max_length=60)
state_province = models.CharField(max_length=30)#default=‘CN‘
country = models.CharField(max_length=50)
website = models.URLField()
def __unicode__(self):
return self.name
class Author(models.Model):
first_name = models.CharField(max_length=30)
last_name = models.CharField(max_length=40)
email = models.EmailField(blank=True)
def __unicode__(self):
return self.last_name
class Book(models.Model):
title = models.CharField(max_length=100)
authors = models.ManyToManyField(Author)
publisher = models.ForeignKey(Publisher)
publication_date = models.DateField()
def __unicode__(self):
return self.title
在/mysite/mysite目录下编辑settings.py文件 添加app
INSTALLED_APPS = [
‘django.contrib.admin‘,
‘django.contrib.auth‘,
‘django.contrib.contenttypes‘,
‘django.contrib.sessions‘,
‘django.contrib.messages‘,
‘django.contrib.staticfiles‘,
‘myapp‘,
依次运行下面两条命令 创建表
python manage.py makemigrations
python manage.py migrate
创建站点用户：
python manage.py createsuperuser
启动django：pyhon manage.py runserver 0.0.0.0:9999
这样就可以在浏览器上登录站点 http://192.168.177.130:9999/admin
输入刚才创建的用户和密码进入进行管理：
在/mysite/myapp目录下编辑admin.py文件 就会在站点页面中出现：
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.contrib import admin
from myapp.models import Publisher,Author,Book
# Register your models here.
class Bookadmin(admin.ModelAdmin):
search_fields = (‘title‘,)#查询
filter_horizontal = (‘authors‘,)#横向查询选择
#filter_vertical = (‘authors‘,)纵向
list_display = (‘title‘,‘publisher‘,‘publication_date‘)#显示其他信息功能
list_filter = (‘title‘,‘publisher‘,‘publication_date‘)#右边分类功能
ordering = (‘-publication_date‘,)#其他信息的排序功能
#fields =(‘title‘) 排序功能
admin.site.register(Publisher)
admin.site.register(Author)
admin.site.register(Book,Bookadmin)
可以在页面上添加表数据
下图是在Book中添加的各种功能
