Hello,
I have some legacy oracle database against which I run inspectdb command.
One column in the DB has type NUMBER (without precision and scale) and
what I got from django is:
entity_id = models.DecimalField(unique=True, null=True, max_digits=0,
decimal_places=-127, blank=True)
If I now run syndb trying to generate schema from the model I will get
the error:
Error: One or more models did not validate:
DecimalFields require a "decimal_places" attribute that is a
non-negative integer.
DecimalFields require a "max_digits" attribute that is a positive integer.
My question is: how should I modify entity_id type oin the model to
get NUMBER generated in oracle?
BTW. Don't you think this is bug to generate model with inspectdb
which is invalid if you run it using syncdb?
Kind regards,
Michael Nowotka

As you may have read that, it states few things:
"This feature is meant as a shortcut, not as definitive model
generation.". No, there is no guarantee that syncdb will work. There
might be fields that canno't be mapped correctly and particulary order
might be totally off.
And on top of that, there is note that inspectdb works (only) with
PostgreSQL, MySQL and SQLite. No Oracle mentioned.
When I mapped my models from Oracle I used 3rd party tool MyGeneration
[1] to generate mappings. It was more easier and I had full control over
how to map database to Django ORM. Though ordering problem still was
persstent but at least I got models more or less right from the very
beginning.
