TemplateDoesNotExist: postgres/widgets/split_array.html

[linluc]

In my model I use:

user_choices = ArrayField(models.BooleanField(), default=[], size=5)

then on the form, in the widgets section (first import: from django.contrib.postgres.forms import SplitArrayWidget):

'user_choices' : SplitArrayWidget(forms.CheckboxInput(),5)

The above combination throws:

Django Version: 2.0.1
Exception Type: TemplateDoesNotExist
Exception Value: postgres/widgets/split_array.html

The issue seems easy to fix, by either fixing the path in "/lib/python3.4/site-packages/django/contrib/postgres/forms/array.py", which currently reads:

template_name = 'postgres/widgets/split_array.html'

or by moving the postgres template directory, which is located one level above.

Probably you don't have django.contrib.postgres in your INSTALLED_APPS, or you've otherwise incorrectly configured ​widget rendering.
