What's the proper way to set up for multiple environments on django?

Question

I followed a tutorial to have a production and local environment for my django app. But when I pushed it to heroku it was rejected. it worked fine locally though. I created a folder called settings and made it a module by putting __init__.py insde of it. I changed the name of my original settings.py and named it Old_settings .py. I then created a file called base.py with all my original settings.py code. Then inside of the init file I did this

from .base import *

try:
    from .local import *
except:
    pass

try:
    from .production import *
except:
    pass

in the the production

import os
import dj_database_url

BASE_DIR = os.path.dirname(os.path.dirname(os.path.dirname(__file__)))
PROJECT_ROOT = os.path.dirname(os.path.abspath(__file__))
SECRET_KEY = os.environ['SECRET_KEY']
DEBUG = False

in the local

import os
import dj_database_url

BASE_DIR = os.path.dirname(os.path.dirname(os.path.dirname(__file__)))
PROJECT_ROOT = os.path.dirname(os.path.abspath(__file__))
SECRET_KEY = '------------------------------------------'
DEBUG = True

I also changed this

BASE_DIR = os.path.dirname(os.path.dirname(__file__))

to this

BASE_DIR = os.path.dirname(os.path.dirname(os.path.dirname(__file__)))

but when i push it to heroku master it's rejeced. What am I missing

    remote:        You may need to update application code to resolve this error.
    remote:        Or, you can disable collectstatic for this application:

    remote:           $ heroku config:set DISABLE_COLLECTSTATIC=1

my old path was

 src/gettingstarted/settings.py 

but now it's

src/gettingstarted/settings/
                        __init__.py
                        base.py
                        local.py
                        production.py

I think it's a directory issue But I'm a bit confused as to how to do correct it
