In the previous post about optimizing Django database queries I showed how to detect and improper use of indexes and what Django creates by default. Today I’d like to show a better usage of indexing on a potentially expensive operation which is text searching. Task: Search an Author By Name As you might remember the […]
Optimizing Django Database Queries
Before we move on to the topic, I’d like to apologize for the irregular updates, but I’m going through a few courses that take a lot of time. On the other hand, from time to time they result in inspirations for new posts. One of such a case is a course focused on working with […]
