Django - How to specify which field a validation fails on?

Question

I have this model I\'m showing in the admin page:

class Dog(models.Model):
    bark_volume = models.DecimalField(...
    unladen_speed = models.DecimalField(...
         


        

Answer 1

The simplest way to validate this particular case would be:

from django.core.validators import MinValueValidator
from django.utils.translation import ugettext_lazy as _

class Dog(models.Model):
    bark_volume = models.DecimalField(
        ..., validators=[MinValueValidator(5, message=_("Must be louder!"))]
