Settle for a dialled-down version, until I figure out the Django back-end configuration

language: python

python:
  - 2.6
  - 2.7

install:
  - pip install -r requirements.txt --use-mirrors
  - pip install pep8 --use-mirrors

before_script:
  - pep8 --exclude=migrations --ignore=E501,E225 forum, _postinstall

pep8 --select=X000 dir

        'default': {
            'ENGINE':  'django.db.backends.postgresql_psycopg2',
            'NAME':    'template1',
            'USER':     env['DOTCLOUD_DB_SQL_LOGIN'],
            'PASSWORD': env['DOTCLOUD_DB_SQL_PASSWORD'],
            'HOST':     env['DOTCLOUD_DB_SQL_HOST'],
            'PORT':     int(env['DOTCLOUD_DB_SQL_PORT']),
        },
        'travis': {
            'ENGINE':   'django.db.backends.postgresql_psycopg2',
            'NAME':     'ponydb',
            'USER':     'postgres',
            'PASSWORD': '',
            'HOST':     'localhost',
            'PORT':     '',
        }

Problems importing wsgi.py:

For some reason, you have to define both the DJANGO_SETTINGS_MODULE and PYTHONPATH in order for the local set-up to work. The PYTHONPATH is designated as your Django project dir, while the settings module is yourproject.settings---sometimes yourproject.settings.work_environment.
