bug(thesis): Thesis.__str__ causes N+1 queries via authors.all()

[thejoeejoee]

Description

Thesis.__str__() in django/apps/thesis/models/thesis.py calls self.authors.all(), which fires a database query every time the thesis is converted to a string.

def __str__(self):
    return '{}: {}'.format(', '.join(str(a) for a in self.authors.all()), self.title)

In admin views, logging, serializer __repr__, or anywhere theses are listed, this creates an N+1 query problem — one extra query per thesis instance.

Severity

Medium — performance degradation, especially in admin and logging contexts.

Location

django/apps/thesis/models/thesis.py — __str__()

Fix

Either cache the author names on the model, use prefetch_related('authors') consistently, or simplify __str__ to not require the relation (e.g., use self.title only).
