Django 2.0 Support

[bobort]

ForeignKeys require an on_delete argument. Therefore, CreatingUserField doesn't work. Please update for Django 2.0 support.

I'm currently working on 2.0 support (PR #55), but I can't tell how far I am. I keep running into new things that doesn't work. Also, I'm not sure we'll be able to get my PR merged in and pushed to PyPI. But I'm focusing on fixing the code first :)

I, too, am having problems with 2.0 on a large application we are trying to modernize. I get "missing 1 required positional argument: 'on_delete'" on startup.

I'm also looking for Django 2.0 support. This #55 seems to take care of the issues. Definitely would appreciate if this were merged and updated on pypi.

[dakab1]

Hi
Is there any solution to this in Django version 2.0 yet?

[MHzarini]

come on guys, i need this

[JanMalte]

@decibyte @vvangelovski Which issues are still open and prevent a release with Django 2.0 support?

[PeterSchwarzHPI]

Any news over here?

[Fhall21]

Hey there! Still getting the error:
TypeError: __initi__() missing 1 required positional argument: 'on_delete
from line 14 in fields.py:
super(LastUserField, self).__init__(to = to, null = null, editable = editable, ** kwargs)
Is there any news on the progress?

[pawisoon]

HI there!
I have same issue on Django 2.1.5
TypeError: __init__() missing 1 required positional argument: 'on_delete'

[decibyte]

For anyone running into this problem: I'd suggest installing from GitHub instead of PyPI, untill @vvangelovski finds the time to push a new version to PyPI.

[AbhiRawat95]

@decibyte any update on this issue? Any update on when it will be pushed to PyPI.

For people who need urgent django compatibility, I shamelessly advise to use https://github.com/pakal/django-compat-patcher until all dependencies are updated to Django2
