Django 學(xué)習(xí)記錄（一）

jack_sir

1，在ubuntu環(huán)境下安裝django：

sudo apt-get install python-django

 

2，安裝python mysql相關(guān)的支持庫(kù)文件：

sudo apt-get install mysql-server python-mysqldb

 

3，開(kāi)始創(chuàng)建一個(gè)django的project：

django-admin startproject mysite

會(huì)在mysql目錄下面自動(dòng)生成四個(gè)文件：

mysite/
    __init__.py
    manage.py
    settings.py
    urls.py

4，首先配置settings.py中數(shù)據(jù)庫(kù)相關(guān)的設(shè)置：（這里使用mysql為列）

修改數(shù)據(jù)庫(kù)配置：

DATABASE_ENGINE = 'mysql'           # 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
DATABASE_NAME = 'dbname'             # Or path to database file if using sqlite3.
DATABASE_USER = 'dbuser'             # Not used with sqlite3.
DATABASE_PASSWORD = 'password'         # Not used with sqlite3.
DATABASE_HOST = '127.0.0.1'             # Set to empty string for localhost. Not used with sqlite3.
DATABASE_PORT = '3306'             # Set to empty string for default. Not used with sqlite3.

修改時(shí)區(qū)：

TIME_ZONE = 'Asia/Shanghai'

修改系統(tǒng)顯示語(yǔ)言：

LANGUAGE_CODE = 'zh-cn'

在INSTALLED_APPS加入后臺(tái)相關(guān)內(nèi)容：

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.admin',
    'django.contrib.admindocs',
)

5、同步數(shù)據(jù)庫(kù)信息、并添加管理后臺(tái)用戶(hù)：

ubuntu:~/mysite$ python manage.py syncdb           
Creating table auth_permission
Creating table auth_group
Creating table auth_user
Creating table auth_message
Creating table django_content_type
Creating table django_session
Creating table django_site
Creating table django_admin_log

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
Username (Leave blank to use 'zhaozhigang'): admin
E-mail address: admin@3cc.com.cn
Password:
Password (again):
Superuser created successfully.
Installing index for auth.Permission model
Installing index for auth.Message model
Installing index for admin.LogEntry model

6、設(shè)置urls.py開(kāi)通后臺(tái)管理訪(fǎng)問(wèn)設(shè)置：

ubuntu:~/mysite$ cat urls.py
from django.conf.urls.defaults import *

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
from mysite.hello import hello
from mysite.currtime import *
admin.autodiscover()

urlpatterns = patterns('',
    # Example:
    # (r'^mysite/', include('mysite.foo.urls')),

    # Uncomment the admin/doc line below and add 'django.contrib.admindocs'
    # to INSTALLED_APPS to enable admin documentation:
    (r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    (r'^admin/', include(admin.site.urls)),
)

7，啟動(dòng)django的web服務(wù)：

ubuntu:~/mysite$ python manage.py runserver 0.0.0.0:8000
Validating models...
0 errors found

Django version 1.1.1, using settings 'mysite.settings'
Development server is running at http://0.0.0.0:8000/
Quit the server with CONTROL-C.

[14/Jan/2011 23:23:28] "GET /admin/ HTTP/1.1" 200 1907
[14/Jan/2011 23:24:01] "GET /admin/doc/ HTTP/1.1" 200 2388

8、http://127.0.0.1/admin 即可登陸管理后臺(tái)。

管理后臺(tái)顯示中文：

在setting.py中的MIDDLEWARE_CLASSES添加：

 'django.middleware.locale.LocaleMiddleware',

 

9、登陸管理后臺(tái)提示：

You don't have permission to edit anything.

你無(wú)權(quán)修改任何東西。

的解決辦法：在url.py總?cè)∠鸻dmin.autodiscover()前面的注釋即可！

admin.autodiscover()
