From ddc5a03c9bec0c59679acb56d24b53425b9e41cf Mon Sep 17 00:00:00 2001 From: Joe Flack Date: Tue, 17 Sep 2024 21:47:26 -0400 Subject: [PATCH] DB Refresh: relationship_graph fix - Update: When app starts and also every time home route is hit, it will now update relationship_graph if it is out of date. General updates - Codestyle and comment updates - Moved some code that was causing PyCharm debugger to run tests inside of a non-test file.
