When it comes to structuring your application the question about a configuration comes up. The easiest way to use a configuration files is to import a configuration module.
For example you could have a file called
websiteconfig.py that looks like this:
DEBUG = False SECRET_KEY = 'mysecretkey' DATABASE_URI = 'sqlite:////tmp/myapp.db
Then you could use it in your application as follows:
import websiteconfig app.debug = websiteconfig.DEBUG app.secret_key = websiteconfig.SECRET_KEY
If you are using packages like outlined in the documentation you can put something like this into your
import websiteconfig as config
Then you can import the config like this in any module:
from yourapplication import config
This makes it very easy to later change the name of the config filename, to load different configuration modules based on environment or to switch the module to an INI file later.
