= Overview
PostgreSQL allows values to be either strings or nulls in `hstore`:
https://www.postgresql.org/docs/9.5/static/hstore.html
It appears that the form and model HStoreFields do not support null
values. Is this something that should be fixed?
= How to reproduce for the form field
{{{
>>> from django.contrib.postgres import forms
>>> field = forms.HStoreField()
>>> field.clean('{"a": null}')
{u'a': u'None'}
}}}
== Expected Behavior
The null has been converted to a string, when it should actually be the
None value
= How to reproduce for the model field
{{{
>>> from django.contrib.postgres.fields import HStoreField
>>> field = HStoreField()
>>> field.clean({'a': None}, None)
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/Users/dhoffman/.envs/brain-campaign/lib/python2.7/site-
packages/django/db/models/fields/__init__.py", line 588, in clean
self.validate(value, model_instance)
File "/Users/dhoffman/.envs/brain-campaign/lib/python2.7/site-
packages/django/contrib/postgres/fields/hstore.py", line 36, in validate
params={'key': key},
ValidationError: [u'The value of "a" is not a string.']
}}}
== Expected Behavior
This should actually be allowed without error.
