Form with IntegerRangeField does not validate

[George Tantiras]

In a fresh Django installation:

from django import forms
from django.contrib.postgres.forms import IntegerRangeField
from psycopg2.extras import NumericRange


class A(forms.Form):
    lifespan = IntegerRangeField(required=True)


>>> data = {'lifespan': NumericRange(1918, 1999)} 
>>> p = A(data=data)
>>> p.data
{'lifespan': NumericRange(1918, 1999, '[)')}
>>> p.is_valid()
False
>>> p.errors
{'lifespan': ['This field is required.']}
>>> p.cleaned_data
{}

I discovered this behaviour while trying to test the clean method of a ModelForm with this field.

data needs to be in the form that a Form would recieve it. ​`RangeWidget` is based off-of `MultiWidget` so it’s expecting a _0, _1 pair, rather than a NumericRange:

>>> from django import forms
>>> from django.contrib.postgres.forms import IntegerRangeField
>>> from psycopg2.extras import NumericRange
>>> class A(forms.Form):
...     lifespan = IntegerRangeField(required=True)
...
>>> data = {"lifespan_0": 1918, "lifespan_1": 1999}
>>> p = A(data=data)
>>> p.data
{'lifespan_0': 1918, 'lifespan_1': 1999}
>>> p.is_valid()
True
>>> p.errors
{}
>>> p.cleaned_data
{'lifespan': NumericRange(1918, 1999, '[)')}

Thank you, it works!

I blindly followed the docs of ​SimpleArrayField and tried to accordingly assign the value in the Form.

The thing is that neither ​MultiWidget nor ​RangeWidget have any examples.
