Django Migrations without Downtime

The following instructions describe a set of processes allowing you to run Django database migrations against a production database without having to bring the web service down.

Note that in the below instructions, migrations are all run manually at explicit points, and are not an automatic part of the deployment process.

Adding a (nullable) field or a new table

Make the model or column addition in your code.

The following recipes are sampled from a trained neural net. You can find the repo to train your own neural net here: https://github.com/karpathy/char-rnn Thanks to Andrej Karpathy for the great code! It's really easy to setup.

The recipes I used for training the char-rnn are from a recipe collection called ffts.com And here is the actual zipped data (uncompressed ~35 MB) I used for training. The ZIP is also archived @ archive.org in case the original links becomes invalid in the future.

	Go to Bitbucket and create a new repository (its better to have an empty repo)
	git clone [email protected]:abc/myforkedrepo.git
	cd myforkedrepo

	Now add Github repo as a new remote in Bitbucket called "sync"
	git remote add sync [email protected]:def/originalrepo.git

	Verify what are the remotes currently being setup for "myforkedrepo". This following command should show "fetch" and "push" for two remotes i.e. "origin" and "sync"
	git remote -v
