using CKeditor with django

CKEditor is the new version of famous FCKeditor. In this artical, I note the way we use CKEditor with django-1.1

Assumes that you have python and django-1.1 installed in your system. There're 2 steps that you should follow

1. Download ckeditor from http://ckeditor.com/
2. Download django-ck from http://code.google.com/p/django-ck/downloads/list

Then, take a look at wiki page at http://code.google.com/p/django-ck/w/list

All done, extract the ckeditor and copy it into your media folder. This step related to

• Serve the static file in django http://docs.djangoproject.com/en/dev/howto/static-files/. Remember that you must avoid the url name /media resembling to admin media prefix.

Make some changes on settings.py, create CKEDITOR_PATH as exact URL to the ckeditor.js. Open ck/fields.py, set CKeditor.BasePath = "%s/js/ckeditor/";  Don't forget to add 'ck' to your installed apps in settings.py

That okies, all you need is follow the guide in wiki and make admin works.

backup and restore mysql in ubuntu

although i use ubuntu with shell, you can use whatever linux's distribution, command should like the same

backup mysqlmysqldump -u [username] -p [password] [database'name] > [backup'sname]
exp: mysqldump -u root -p 123 mysite > mysite.bak.sql


restore from file backupmysql -u [username] -p [password] [database'name] < [backup'sname]

note that the only different is mysql <> mysqldump and > <> <exp: mysql -u root -p 123 mysite < mysite.bak.sql
