2) to run the django project against what to test you api  you need: 

coreapi==2.1.1
Django==1.10.3
djangorestframework==3.5.3
itypes==1.1.0
Pillow==3.4.2
psycopg2==2.6.2
requests==2.12.3
uritemplate==3.0.0

also, as psql server. But you can set the project up with sql-lite. In that case you need to set it up with different parameters. 
Currently the code in settings.py ... The "linux" check is there for the cases when i deploy the code to aws.
if(sys.platform == "linux"):
	DATABASES = {
		'default': {
			'ENGINE': 'django.db.backends.postgresql_psycopg2',
			'NAME': "ebdb",
			'USER': "administraator",
			'PASSWORD': "Nossuonbeebi92",
			'HOST': "aaghowdt333l1r.cbfuxup0zpv7.us-west-2.rds.amazonaws.com",
			'PORT': 5432,
		}
	}
else:
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.postgresql_psycopg2',
            'NAME': 'uus',
            'USER': 'admin',
            'PASSWORD': 'Nossuonbeebi92',
            'HOST': 'localhost',
            'PORT': '5432',
        }
    }
