Python Django連接數(shù)據(jù)庫(kù)

10年積累的成都做網(wǎng)站、成都網(wǎng)站設(shè)計(jì)經(jīng)驗(yàn)，可以快速應(yīng)對(duì)客戶對(duì)網(wǎng)站的新想法和需求。提供各種問(wèn)題對(duì)應(yīng)的解決方案。讓選擇我們的客戶得到更好、更有力的網(wǎng)絡(luò)服務(wù)。我雖然不認(rèn)識(shí)你，你也不認(rèn)識(shí)我。但先制作網(wǎng)站后付款的網(wǎng)站建設(shè)流程，更有正安免費(fèi)網(wǎng)站建設(shè)讓你可以放心的選擇與我們合作。

一、安裝數(shù)據(jù)庫(kù)

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

二、查看是否安裝了python數(shù)據(jù)庫(kù)組件

# rpm -qa | grep MySQL-python

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

三、創(chuàng)建數(shù)據(jù)庫(kù)

# mysql -uroot -p

mysql> create database csvt character set utf8;

四、創(chuàng)建工程，應(yīng)用

# django-admin.py startproject csvt03

# cd csvt03

# django-admin.py startapp blog

# vim settings.py (添加應(yīng)用，修改數(shù)據(jù)庫(kù)類(lèi)型連接用戶以及密碼)

...

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、創(chuàng)建表

# cat blog/models.py

from django.db import models

class Employee(models.Model):

name = models.CharField(max_length=20)

//（會(huì)在數(shù)據(jù)庫(kù)csvt employee表中添加一個(gè)name字段）

六、同步數(shù)據(jù)庫(kù)，將數(shù)據(jù)寫(xiě)入數(shù)據(jù)庫(kù)

# 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、查看數(shù)據(jù)庫(kù)

mysql> use csvt;

Database changed

mysql> show tables;

+----------------------------+

| Tables_in_csvt |

+----------------------------+

| auth_group |

| auth_group_permissions |

| auth_message |

| auth_permission |

| auth_user |

| auth_user_groups |

| auth_user_user_permissions |

| blog_employee |

| django_content_type |

| django_session |

| django_site |

+----------------------------+

11 rows in set (0.00 sec)

mysql> desc blog_employee;

+-------+-------------+------+-----+---------+----------------+

+-------+-------------+------+-----+---------+----------------+

| id | int(11) | NO | PRI | NULL | auto_increment |

+-------+-------------+------+-----+---------+----------------+
