Migration broken from 0.2.19 (and older)

This is followup for #16.

With #25 the migration from 0.2.20 and 0.2.21 is working fine, however users upgrading from 0.2.19 and older will still end up with error.

It can end up with error described in #16:

KeyError: u"Migration social_django.0002_add_related_name dependencies reference nonexistent parent node (u'social_django', u'0001_initial')"

Or it can pop up as error while validating relations (see https://github.com/WeblateOrg/weblate/issues/1344):

ValueError: The field accounts.VerifiedEmail.social was declared with a lazy reference to 'social_django.usersocialauth', but app 'social_django' isn't installed.

The problem is that Django does not see the old migrations as they are just half applied (due to missing social_auth ones):

manage.py showmigrations
...
social_django
 [ ] 0005_auto_20160727_2333 (1 squashed migrations)
 [ ] 0006_partial
...

This is what is stored in the database:

id	app	name	applied
70	default	0001_initial	2017-02-01 15:03:35.625824
112	default	0002_add_related_name	2017-02-01 15:03:41.684870
113	default	0003_alter_email_max_length	2017-02-01 15:03:41.739056
114	default	0004_auto_20160423_0400	2017-02-01 15:03:41.877357

@coriolinus I had that same issue after hammering (incorrectly) past the issue described in this comment: https://github.com/python-social-auth/social-app-django/issues/22#issuecomment-274850091

Doing the following db stuff got me past that issue.

$ update django_migrations set app='social_django' where app='default';

Ref: https://github.com/python-social-auth/social-app-django/issues/22#issuecomment-274856118

Then I encountered your error @Kuein and did the following:

$ python manage.py migrate social_django 0001 --fake

and then finished the migrations for social_django:

$ python manage.py migrate social_django

Then <span class="emoji-outer emoji-sizer"><span class="emoji-inner" style="background: url(chrome-extension://immhpnclomdloikkpcefncmfgjbkojmh/emoji-data/sheet_apple_64.png);background-position:80% 47.5%;background-size:4100%"></span></span> and <span class="emoji-outer emoji-sizer"><span class="emoji-inner" style="background: url(chrome-extension://immhpnclomdloikkpcefncmfgjbkojmh/emoji-data/sheet_apple_64.png);background-position:12.5% 72.5%;background-size:4100%"></span></span> appeared… and everything works!

I’m encountering the same isssue, and the steps listed in the migrations guide do not help:

$ pip list --format=columns | grep social

rest-social-auth          0.5.0
social-auth-app-django    1.1.0
social-auth-core          1.2.0
$ ./manage.py showmigrations social_django
social_django
