How to load config file in python from an external module

Question

I have a config module (myConfig.py) present in a library for which i created a standard distribution package using setuptools.

  --configPackage
    |
    | ---- myConfig.py
    | ---- __init__.py

myConfig.py is a key value pair like this:

MY_NAME = 'myname'
MY_AGE = '99'

Now I have another python project where I import this config module like this

import configPackage.myConfig as customConfig

If this config file was native to my python project and had not come from an external project then I would have done something like this:

app = Flask(__name__) 
app.config.from_object('app.configPackage.config')

where config is actually config.py file under configPackage.

and any key value pair in config.py could then be accessed as

 myName = app.config['MY_NAME']

My problem is that I am not able to load the external config file in the above mentioned way for a native config file. What I have tried is this which doesn't work:

import configPackage.myConfig as customConfig

app = Flask(__name__) 
app.config.from_object(customConfig)
myName = app.config['MY_NAME']

I get the following error

model_name = app.config['model_name'] KeyError: 'model_name'

Which means that it is not able to load the config file from external module correctly. Can anyone tell me the right way to accomplish this ?

Try this,

in your __init__.py of configPackage import myConfig as shown below

import configPackage.myConfig as myConfig

And in your other app try

app.config.from_object('configPackage.myConfig')
