Comment (by Dmitry Mugtasimov):
If you also waiting for the fix and have a simple through model for some
reason you may use `auto_created = True` to trick Django Admin:
{{{
class JobTitleExperienceThrough(models.Model):
title = models.ForeignKey('JobTitle', on_delete=models.CASCADE,
related_name='experiences_through')
experience = models.ForeignKey('Experience', on_delete=models.CASCADE,
related_name='titles_trough')
class Meta:
# TODO(dmu) MEDIUM: Remove `auto_created = True` after these
issues are fixed:
# https://code.djangoproject.com/ticket/12203
and
# https://github.com/django/django/pull/10829
auto_created = True
class JobTitle(models.Model):
name = models.CharField(max_length=64)
role = models.ForeignKey('JobRole', on_delete=models.CASCADE,
related_name='titles')
experiences = models.ManyToManyField('Experience',
through='JobTitleExperienceThrough',
related_name='titles',
blank=True)
class Meta:
ordering = ('id',)
}}}
