Hi, this is my project: https://github.com/netoarmando/tccweb

I'm using this approach to use configuration:

import tccweb.settings


def create_app():

    app = Flask(__name__)
    app.config.from_object(settings.DevelopmentConfig)

    app.register_module(admin)


    return app

 on settings.py:

class Config(object):
    SECRET_KEY = '\xa3Lc}\xf4\xa8\x8e
\xd4\x1c,I2\xb4j*3e\xbc\xa9\x03\xca\x7f\xe1'
    DEBUG = False
    TESTING = False
    SQLALCHEMY_ECHO = False

class ProductionConfig(Config):
    SQLALCHEMY_DATABASE_URI = 'postgresql://user:password@localhost/mydatabase'

class DevelopmentConfig(Config):
    DEBUG = True
    SQLALCHEMY_DATABASE_URI = 'sqlite:///%s/database-development.db' %
os.path.dirname(__file__)

class TestinConfig(Config):

    TESTING = True

What I want to know is how a module can acess a new Constraint that I could
set in here?
For an example:

class Config(object):
    UPLOAD_FOLDER = '/temp'

Hi,

If I understand your question, you'd like to access config directives
in your code.  Once your app is initialized:

app = Flask(__name__)
app.config.from_object(config) # whatever your config obj is

You can:

app.config['UPLOAD_FOLDER']

where app.config is a dictionary (specifically a subclass of dict).
You can use all dict methods in your code.

Hey,

You can access it simply by this-

from flask import current_app

conf_value = current_app.config['UPLOAD_FOLDER']
