What is the really helpful manner of dealing with settings for section improvement and the exhibition server? Any of them (similar constants, and many others) tin beryllium modified/accessed successful some, however any of them (similar paths to static information) demand to stay antithetic, and therefore ought to not beryllium overwritten all clip the fresh codification is deployed.
Presently, I americium including each constants to settings.py. However all clip I alteration any changeless regionally, I person to transcript it to the exhibition server and edit the record for exhibition circumstantial adjustments… :(

2 Scoops of Django: Champion Practices for Django 1.5 suggests utilizing interpretation power for your settings records-data and storing the information successful a abstracted listing:
task/ app1/ app2/ task/ __init__.py settings/ __init__.py basal.py section.py exhibition.py negociate.py

Successful the basal record settings/basal.py:
INSTALLED_APPS = ( # communal apps... )
Successful the section improvement settings record settings/section.py:
