 # This is an auto-generated Django model module.

-# autogenerated by:
-# $ python manage.py inspectdb
-
 # You'll have to do the following manually to clean this up:
 #   * Rearrange models' order
 #   * Make sure each model has one field with primary_key=True
+#   * Make sure each ForeignKey has `on_delete` set to the desired behavior.
 #   * Remove `managed = False` lines if you wish to allow Django to create, modify, and delete the table
 # Feel free to rename the models, but don't rename db_table values or field names.
-#
-# Also note: You'll have to insert the output of 'django-admin.py sqlcustom [app_label]'
-# into your database.
