Re: Error during template rendering

[Antonis Christofides]

Hi!

The error message 'relation "curriculum_standard" does not exist' has been produced by PostgreSQL, and Django merely repeats it. In other words, Django is telling you that while it was doing what it was doing, an error occurred in the RDBMS, and it is showing you the error message that the RDBMS returned.

People who, unlike me, have studied relational calculus often use the word "relation" for what I call a "table". I don't know why. I once picked up a relational calculus book to take a look, but it was too heavy for my taste :-) (If someone can explain in simple terms I'm eager to read.) So the system is telling you that table "curriculum_standard" does not exist.

This probably means that you need to run "python manage.py migrate".

Regards,

Antonis
