Preventing nested queries when opening a request - PM4EH-222
Issue & Reproduction Steps
The request was overflowing memory due to nested queries.
Solution
Refactor the initial query, using native features of Laravel, to reduce the number of queries, and later cache a collection of screens.
As $screen must be a new versioning instance, it must not be cached.
In request 143, the number of queries was reduced from 336 to 28, mitigating the problem.
How to Test
As an admin user, open a request (/requests/{request}) that contains tokens and screens. The displayed HTML should be exactly as it was before.
