How to improved query performance in Django admin search on related fields (MySQL)

Question

In Django I have this:

models.py

class Book(models.Model):
    isbn = models.CharField(max_length=16, db_index=True)
    title = mod         


        

Answer 1

You can redefine get_changelist for ModelAdmin subclass and try to optimize query manually there. For example, ISBN can be looked up with exact match instead of icontains, and you can add subqueries on Book to work faster.
