What is the recommended way to configure my application
find the various database and/or configuration files it needs?
Recommemded by whom? A lot depends on the OS. Apple for
example have one set of recommendations for MacOS, Windows
has another and Linux has several to choose from!
For instance my folder layout:
/path_to_app/app.py
/path_to_app/lib/
/path_to_app/database/
/path_to_app/config/
/path_to_app/photos
.... and so on.
I would like to make an .ini in the config folder
Seems fair enough, however on a Unix system you should also
consider allowing the user to have their own personalised version
in their home directory. Thus at startup you get the current user
ID / home directory and look for a suitable config file. If it exists
read it, if not read the default one in your config directory.
1) How does my main app file find the config file in the first place?
Generally use a relative path so normally your app will run from
its home folder so you can look in ./config. You might also set a
system environment variable - for example the CLASSPATH
or PYTHONPATH variables, or the ORACLE_HOME used by
Oracle for their database. If the environment var is not set then
look in ./config
2) How should I point to those other folders in the ini file?
Once you locate config the others are simply ../xxx relative
to config.
