Form validation of a comma separated decimal field works when calling from external script and fails on calling from django shell (ipython). Starting a new Project I got the following files: local_forms/ ├── local_forms │ ├── __init__.py │ ├── models.py │ ├── settings.py │ ├── urls.py │ └── wsgi.py ├── manage.py ├── my_form.py ├── test_form.py local_forms/models.py: from django.db import models class MyModel

For example I have yes_no_required = models.NullBooleanField() and I would like to have 'yes I acknowledge this' , 'no, I do not like this' and 'I do not know now' mapping to yes, no and required accordingly. 回答1: I spent half an hour putting
