Positive integer form field with max lenght

[emonk]

Hi people.
This is my doubt

I need make a form field with this restrictions:

_field content must be only integers numbers and postive.
_filed content must have a max lenght, for example 8 characters.

I am confused beacuse models.PositiveIntegerField has no have max_length atribute (have a max_value), but models.CharacterField have max_lenght atribute.

Any idea? :S

Thanks a lot.

Firstly, if you're talking about forms, you don't want to look at
models.PostiveIntegerField -- that's for models. Instead, look at
django.forms.*

Secondly, the equivalent concept to string length is max_value and
min_value for the form field IntegerField. It sounds like you want

IntegerField(min_value=0, max_value=99999999)

See http://docs.djangoproject.com/en/dev/ref/forms/fields/#integerfield
for the documentation.

An integer doesn't usually have a max length, if at all it has a max
value. Which in your case sounds like 99.999.999.
To actually achieve what you want read through the form validation
docs http://docs.djangoproject.com/en/dev/ref/forms/validation/
