Workflows (States) in Django

I'm going to cover a simple, but effective, utility for managing state and transitions (aka workflow). We often need to store the state (status) of a model and it should only be in one state at a time.

Common Software Uses

• Publishing (Draft->Approved->Published->Expired->Deleted)

# requires imagemagick and ffmpeg (tested with latest versions)
# make sure you set an INFILE variable first

# get GIF info
video=$(ffmpeg -i "$INFILE" 2>&1 /dev/null | grep "Video:");

# get GIF Frames per second
fps=$(echo "$video" | sed -n "s/.* \([0-9.]*\) fps.*/\1/p");

# a convinience variable so we can easily set FPS on the video
