Templates and Logic - Building SaaS #45

Notes

In this episode, we added content to a template and talked about the N+1 query bug. I also worked tricky logic involving date handling.

The first change was to update a course page to include a new icon for any course task that should be graded. After adding this, we hit an N+1 query bug, which is a performance bug that happens when code queries a database in a loop. We talked about why this happens and how to fix it.

After finishing that issue, we switched gears and worked on a tricky logic bug. I need a daily view to fetch data and factor in the relative time shift between the selected day and today. We wrote an involved test to simulate the right conditions and then fixed the code to handle the date shift properly.
