An oemof extension to use the oemof related postgis database.

To use this extension you have to have access to the oemof postgis database.

The oemof code will be released in early 2016 but you can try this extension already with the feedinlib. If you are interested to join the oemof database project please contact us.

Configuration

As the purpose of this package is to facilitate usage of the oemof database, it needs to know how to connect to this database. Being part of oemof, oemof_pg looks for this configuration in the file config.ini in a directory called .oemof in your home directory.

To configure database access this file has to have a section [postGIS] section containing the necessary options, like this:

[postGIS]
username = username under which to connect to the database
database = name of the database from which to read
host     = host to connect to
port     = port to connect to
pw       = password used to connect with the given username (OPTIONAL)

The password is optional. If you don't want to store the password in the config.ini, you may store it using the keyring package, which is a dependency of oemof_pg, like this:

>>> import keyring
>>> keyring.set_password("database", "username")

where "database" and "username" have the same values as the corresponding options in config.ini.
