26834	MinValueValidator/MaxValueValidator not forwarded to form field for ModelForm	Sergei Maertens	Clifford Gama	"I just ran into a possible enhancement.

Consider the following model:

{{{
#!python
DEFAULT_RATING = 50
MAX_RATING = 100
MIN_RATING = 0


class KitReviewPropertyRating(models.Model):
    """"""
    Represents properties for a kit review rated on a scale from MIN_RATING to MAX_RATING
    """"""
    kit_review = models.ForeignKey('KitReview', related_name='ratings')
    prop = models.ForeignKey('KitReviewProperty')
    rating = models.PositiveSmallIntegerField(
        _('rating'), default=DEFAULT_RATING,
        validators=[MinValueValidator(MIN_RATING), MaxValueValidator(MAX_RATING)]
    )
}}}

and the matching ModelForm:
{{{
#!python
from django.forms.widgets import NumberInput


class RangeInput(NumberInput):
    input_type = 'range'


class KitReviePropertyRatingForm(forms.ModelForm):

    class Meta:
        model = KitReviewPropertyRating
        fields = ('id', 'prop', 'rating')
        widgets = {
            'rating': RangeInput(attrs={'max': MAX_RATING})
        }
}}}

As you can see, I have to specify the `max` widget attribute manually, otherwise the html input looks like this: `<input type=""range"" name=""rating"" value=""50"" min=""0"">`, instead of the expected `<input type=""range"" name=""rating"" value=""50"" min=""0"" max=""100"">`. I had expected the Min/MaxValueValidator to be 'forwarded' to the form field (via `IntegerField.formfield` method), but no such thing happens. #26786 does add the validators on the model level, based on the db connection used and the limits there, and only if no such validators were present yet.

I'd like to make it so that Min/MaxValueValidators are translated into `min_value`/`max_value` defaults for the `IntegerField.formfield` method, this would be more in line with the expected output and reduce the need to repeat yourself."
