Trouble Migrating database schema to Heroku (Postgres)

I have everything set up in my local environment and the code for my website up on the Heroku server, I'm just having serious trouble getting the schema to migrate to the PostgreSQL database on the Heroku server. Whenever I attempt heroku run python manage.py migrate I get the following (this would be an initial migration):

    Running python manage.py migrate on baseballstatview... up, run.1653      (Free)
    Operations to perform:
    Apply all migrations: admin, auth, contenttypes, sessions, statview
    Running migrations:
      Applying contenttypes.0001_initial... OK
      Applying auth.0001_initial... OK
      Applying admin.0001_initial... OK
      Applying admin.0002_logentry_remove_auto_add... OK
      Applying contenttypes.0002_remove_content_type_name... OK
      Applying auth.0002_alter_permission_name_max_length... OK
      Applying auth.0003_alter_user_email_max_length... OK
      Applying auth.0004_alter_user_username_opts... OK
      Applying auth.0005_alter_user_last_login_null... OK
      Applying auth.0006_require_contenttypes_0002... OK
      Applying auth.0007_alter_validators_add_error_messages... OK
      Applying auth.0008_alter_user_username_max_length... OK
      Applying sessions.0001_initial... OK
      Applying statview.0001_initial... OK

Which seems fine but then using heroku pg:info it tells me I have 0 tables, and even further when I run heroku run python manage.py showmigrations this is what I get:

    Running python manage.py showmigrations on baseballstatview... up, run.5059 (Free)
    admin
     [ ] 0001_initial
     [ ] 0002_logentry_remove_auto_add
    auth
     [ ] 0001_initial
     [ ] 0002_alter_permission_name_max_length
     [ ] 0003_alter_user_email_max_length
     [ ] 0004_alter_user_username_opts
     [ ] 0005_alter_user_last_login_null
     [ ] 0006_require_contenttypes_0002
     [ ] 0007_alter_validators_add_error_messages
     [ ] 0008_alter_user_username_max_length
    contenttypes
     [ ] 0001_initial
     [ ] 0002_remove_content_type_name
    sessions
     [ ] 0001_initial
    statview
     [ ] 0001_initial

So it appears that the migrations are not going through and I'm wondering why that's the case. The database is empty, I've tried resetting it and trying again but nothing seems to work.

EDIT: below is the relevant settings.pyfor dj_database_url:

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.postgresql_psycopg2',
    'NAME': 'mlb_data',
    'USER': 'postgres',
    'PASSWORD': 'pw',
    'HOST': 'localhost',
    'PORT': '5432',
 }
}

import dj_database_url

DATABASES['default'] = dj_database_url.config()

SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')

ALLOWED_HOSTS = ['*']

DEBUG = False

try:
    from .local_settings import *
except ImportError:
    pass
