DateTimeField
and TimeField
do not have options to set lower and upper bounds. However, it is possible to write validators for any type of field.
A validator to check the date of birth would look something like:
from datetime import date
from django.core.exceptions import ValidatonError
def validate_dob(value):
"""Makes sure that date is been 1990-01-01 and 18 years ago."""
today = date.today()
eighteen_years_ago = today.replace(year=today.year - 18)
if not date(1990, 1, 1) <= value <= eighteen_years_ago:
raise ValidationError("Date must be between %s and %s" % (date(1990,1,1,), eighteen_years_ago)
Then use your validator in your model field.
birth_date = models.DateField(verbose_name='D.O.B', validators=[validate_dob])
