best practice to construct 10x10 grid
I have grid 10x10 populated with int>0. Currently I'm avoiding modelforms all together and doing my own processing, definining it as array and rendering with loop, custom checking with my own validators outside of database Model. Any hints how to standardize it and move to django way of thinking? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

i18n and choices from database
lets say i have a model
from django.utils.translation import ugettext_lazy as _
class Person (models.Model):
GENDER = (
(0, _('Male'),
(1,_('Female')
)
name = models.CharField(maxlength=100)
gender = models.IntegerField(choices=GENDER)
and i show it on the form with localized output
after submit i get values ( 0,"name" ) in the database.
Question is how to show query from database on template with localized
output
TIA,
Damir
