Python Django串連資料庫

一、安裝資料庫

# yum -y install mysql mysql-devel mysql-server

二、查看是否安裝了python資料庫組件

# rpm -qa | grep MySQL-python

MySQL-python-1.2.3-0.3.c1.1.el6.x86_64

三、建立資料庫

# mysql -uroot -p

mysql> create database csvt character set utf8;

四、建立工程，應用

# django-admin.py startproject csvt03

# cd csvt03

# django-admin.py startapp blog

# vim settings.py (添加應用，修改資料庫類型串連使用者以及密碼)

...

DATABASES = {

    ‘default‘: {

        ‘ENGINE‘: ‘django.db.backends.mysql‘,

        ‘NAME‘: ‘csvt‘,

        ‘USER‘: ‘root‘,

        ‘PASSWORD‘: ‘123456‘,

        ‘HOST‘: ‘‘,        

        ‘PORT‘: ‘‘, 

    }

}

............

INSTALLED_APPS = (

    ‘django.contrib.auth‘,

    ‘django.contrib.contenttypes‘,

    ‘django.contrib.sessions‘,

    ‘django.contrib.sites‘,

    ‘django.contrib.messages‘,

    ‘django.contrib.staticfiles‘,

    ‘blog‘,

)

...

五、建立表

# cat blog/models.py

from django.db import models

class Employee(models.Model):

    name = models.CharField(max_length=20)  

//（會在資料庫csvt employee表中添加一個name欄位）

六、同步資料庫，將資料寫入資料庫

# python manage.py syncdb 

Creating tables ...

Creating table auth_permission

Creating table auth_group_permissions

Creating table auth_group

Creating table auth_user_user_permissions

Creating table auth_user_groups

Creating table auth_user

Creating table auth_message

Creating table django_content_type

Creating table django_session

Creating table django_site

Creating table blog_employee

You just installed Django‘s auth system, which means you don‘t have any superusers defined.

Would you like to create one now? (yes/no): yes

Installing custom SQL ...

Installing indexes ...

No fixtures found.

七、查看資料庫

mysql> use csvt;

Database changed

mysql> show tables;
