Go the extra step and setup ngnix or another simple http server. You will

Hi:
Mike Ramirez Thanks for your response so quickly. I install what I
recommended, but continued presenting the same problem.

Did you mean how to delete records of A for which there are no records
in B pointing to them through the foreign key "a", right?

Yes, a filter is a good option. For example:
from datetime import datetime
.objects.filter(pub_d

About a legacy db where you put a unique constraint manually it is
recommended to put the option unique to the field so you get
a nice error in the Django forms instead of an error screen.

No. Django's builtin validators has two results: validated or not. If you

Are the accented chars the problem?
Maybe it is related

You can make a custom sort_ by_total() function, create a list from
