In order to use django-fluidinfo you need indicate your Fluidinfo instance and credentials in the settings.py file.
To use the main instance of Fluidinfo you would add something like this:
from fom.session import Fluid
fdb = Fluid() # defaults to http://fluiddb.fluidinfo.com/
fdb.login('username', 'password')
fdb.bind()
For the purposes of testing you might want to use the sandbox version of Fluidinfo like this:
from fom.session import Fluid
fdb = Fluid('http://sandbox.fluidinfo.com') # sandbox's URL
fdb.login('username', 'password')
fdb.bind()
Each time you start your application a Fluidinfo session is created with the appropriate credentials. It is these credentials that are also used by the management command syncfluidinfo.
