Not sure the possibility of this feature, but adding it for tracking purposes. If someone wants to research possible ways to implement this feature then let it be known here.

This might be where the database comes in and stores every spread, total, and moneyline data every time the API is called. Then we can make a graph of the history.

We will need to research how to implement the graphs. How big of a task would setting up the database for it be? If time is on our side to get higher priority features done, I think this could be a really cool feature to have.

We can now see any historical data we capture from the API. As a simple example, say we visit the site at 1:00pm, and again at 2:00pm. We can graph a timeline with those two entries. The image is using raw SQL query as an example, but Django commands is needed to interact with the DB. Look in djangoHelp.txt under "Database Functions" for some examples.

Example where we could graph a specific matchup and sportsbook. With 5 entries, we can make it auto-gen a chart with them. Obviously there was no change here so it will be a straight line. Note that Django is timezone aware.

Testing out queries in SQL like above can be done by getting the SQLite extension by alexcvzz. Connect to our local db.sqlite3 file and you can make a similar query as shown on the left.

Todo

• [x] Do the same for Totals and Money
• [x] Prevent exact duplicates with same last updated
• [x] Research Django + Chart.js. There seems to be a lot of popularity with this method of charting
