Removing the last commit

To remove the last commit from git, you can simply run git reset --hard HEAD^ If you are removing multiple commits from the top, you can run git reset --hard HEAD~2 to remove the last two commits. You can increase the number to remove even more commits.

If you want to "uncommit" the commits, but keep the changes around for reworking, remove the "--hard": git reset HEAD^ which will evict the commits from the branch and from the index, but leave the working tree around.

If you want to save the commits on a new branch name, then run git branch newbranchname before doing the git reset.

# Here's your list of choices that would be displayed in a drop-down 
# element on the web.  It needs to be a tuple, and we define this
# as a variable just for readability/convenience. 
#
# This example has 3 choices, each of which consists of two parts:
# 1. the thing that get strored in your database
# 2. the thing that you see in a dropdown list
LABEL_CHOICES = (

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.
