- dumping and restoring databases from RDS
- connecting to Twitter via oauth using python
- python debugger in Django
Backup and Restore to RDS
mysqldump -h dev-rds.customdomain.com -u root -psecret database_name table_name | gzip > backup.sql.gz
table_name is optional, and you can pass a -9 to gzip to maximize compression
gunzip < backup.sql.gz | mysql -h dev-rds.customdomain.com -u root -psecret database_name
Python Twitter OAuth
Grab oauth library, and drop it on your python path. Don't use the egg because there are problems with it.
If you're using cookie based sessions and developing locally, make sure your callback url is consistent with your local dev url. I had the callback url set to http://127.0.0.1/twitter_callback, but I was accessing the application via http://localhost:8000/, so the cookies weren't being set properly. The fix was to access the app from http://127.0.0.1:8000/ instead.
Python Debugger in Django
import pdb; pdb.set_trace()
Equivalent of 'import ruby-debug; debugger' in ruby.
