displaying of foreignkey or onetoone fields data without database calls

[EricOuma]

PROBLEM
Data on the list view that come from ForeignKey or OneToOne fields trigger database calls

SOLUTION
They should be displayed using the data fetched from typesense hence no database calls should be made.

Avoiding this has been explained in the docs

We recommend displaying data from ForeignKey or OneToOne fields as string attributes using the display decorator to
avoid triggering database queries that will negatively affect performance
Issue #16.

Instead of this in the admin:

@admin.display('Genre')
def genre_name(self, obj):
    return obj.genre.name

Do this:

@admin.display('Genre')
def genre_name(self, obj):
    # genre_name is field in the Collection. You can also store the object url as html
    return obj.genre_name
