Installing fixtures with django's loaddata command overrides objects with the same primary key.
While this is not a problem if you are installing the fixtures against a fresh DB with no data but in case you have
existing data then loading the fixture can be problematic as all the existing rows with the same primary key will be updated
with the new data from the fixture(s)
Using djloaddata to install fixture ensures that no existing rows will be touched and all the objects will only be inserted
while preserving all the relations between model objects.
