I squashed my migrations while trying to fix a migration error, and it produced a second error that I'm confused by.
When I try to migrate my heroku database, I get this error:
$ heroku run -a agorafund python manage.py migrate
Running `python manage.py migrate` attached to terminal... up, run.8709
Traceback (most recent call last):

django.db.migrations.graph.NodeNotFoundError: Migration nonprofits.0001_initial dependencies reference nonexistent parent node (u'payments', u'0001_squashed_0026_bankaccount')
At the end there it says "initial dependencies reference nonexistent parent node. (u'payments', u'0001_squashed_0026_bankaccount')"
But that node clearly exist. "0001_squashed_0026_bankaccount" exists in my payments/migrations folder, and it doesn't have any circular dependencies. (It begins thus:)
class Migration(migrations.Migration):
replaces = [('payments', '0001_initial'), ('payments', '0002_auto_20150820_2150'), ('payments', '0003_auto_20150823_1507'), ('payments', '0004_auto_20150823_1832'), ('payments', '0005_auto_20150828_1441'), ('payments', '0006_auto_20150828_1559'), ('payments', '0007_remove_product_fee_rate'), ('payments', '0008_product_fee_rate'), ('payments', '0009_remove_product_fee_rate'), ('payments', '0010_recurringpaymentitem'), ('payments', '0010_auto_20150905_2132'), ('payments', '0011_merge'), ('payments', '0012_auto_20150908_2316'), ('payments', '0013_auto_20150910_1517'), ('payments', '0014_paymentitem_recurring'), ('payments', '0015_subscription'), ('payments', '0016_paymentitem_subscription'), ('payments', '0017_userexternalpayconf_livepayment'), ('payments', '0018_auto_20150916_1852'), ('payments', '0019_auto_20150916_1858'), ('payments', '0020_auto_20150916_2210'), ('payments', '0021_auto_20150917_0314'), ('payments', '0022_auto_20150917_1556'), ('payments', '0023_userexternalpayconf_newcreditcard'), ('payments', '0024_auto_20150917_2004'), ('payments', '0025_subscription_paymentitem'), ('payments', '0026_bankaccount')]
dependencies = [
('contenttypes', '0002_remove_content_type_name'),
('auth', '0006_require_contenttypes_0002'),
migrations.swappable_dependency(settings.AUTH_USER_MODEL),
]
Meanwhile the nonprofits initial migration begins like thus:
class Migration(migrations.Migration):
dependencies = [
('payments', '0001_squashed_0026_bankaccount'),
]
Any ideas what's going on?
