Hello,
I was working on my django project with version 2.0.
Today I redeployed my development environment and installed the lastest
Django version through pip : 2.1.1
While loading my database fixture to populate it (python manage.py
loaddata data_fixture.json), it raised :
{{{
Traceback (most recent call last):
File "/PROJECTS/SOFTWARES/pvenvs/cvdjango/lib/python3.6/site-
packages/django/db/models/fields/__init__.py", line 2325, in to_python
return uuid.UUID(value)
File "/PROJECTS/SOFTWARES/python366/lib/python3.6/uuid.py", line 140, in
__init__
raise ValueError('badly formed hexadecimal UUID string')
ValueError: badly formed hexadecimal UUID string
During handling of the above exception, another exception occurred:

packages/django/core/serializers/python.py", line 100, in Deserializer

None)

valeur «\xa020\xa0» n'est pas un UUID valide."]:
(cv_frontend.PersonalInfo:pk=20) field_value was 'None'
}}}
I flushed migrations, dropper/recreate database and ran migrations again.
Still has the error...
I could actually still create the object having uuid as PK in the admin
console and link other objects to it.
== Then I began to delete objects in my fixture file and try to run again
loaddata : when I deleted every fixture object that had OneToOne
relationship, it passed!!!
I finally rolled back to Django 2.0 and could run the whole fixture with
no problem!
Does it sound like a bug?
