ktowen / django_partial_date Goto Github PK

I am working on a project that has start and end date fields. Ideally the end date field would be optional.

However PartialDate won't accept an empty string, or None despite what it says in the documentation; or null=True.

These are the kind of errors I have received -

["'' is not a valid date string (YYYY, YYYY-MM, YYYY-MM-DD)"]

How to reproduce:

Make sure you have enabled the custom module in your Python virtual environment:

pip install django-partial-date==1.3.2 django-reversion==5.0.4

Create the following class in the django models.py:

from partial_date import PartialDateField

class Station(models.Model):
    name = models.CharField(max_length=200)
    created = PartialDateField(blank=True, null=True)

Register the administration of the object with reversion in admin.py:

from reversion.admin import VersionAdmin

@admin.register(Station)
class StationAdmin(VersionAdmin):
    pass

run migrations on your commandline:

python manage.py makemigrations
python manage.py migrate

1. Login in the admin interface and create a Station object. Provide only a value for the "name" field and leave all the rest empty. Click save and continue editing.
2. Provide a partial date value in the "Created" the field. E.g. "2020-05". Click save and continue editing
3. Click on history.
4. Click on the older version you created before: unintended behavior: "Could not load Name version - incompatible version data."
5. Click on the latest version with the partial date specified: intended behavior. The version loads properly

Hi, it's great library! One question, if only month and day are available, could django_partial_date store only month and day without year? something like:

dob=PartialDate(datetime.date(0, 9, 21), precision=PartialDate.DAY)

Thanks!

I think we need a PartialDateField in forms because of PartialDateField for models exist.

Is it possible to add utcoffset method to the module?

I'm trying to use it with django-import-export module but they are not compatible.
