Configuration Support about flask

[danjac]

It would be useful to be able to have "config" as a threadlocal or global object. For example:

config = dict("some_value"="xyz")
app = Flask(__name__, config=config)

And elsewhere in your code:

from flask import config

@app.route("/")
def index():
    assert config['some_value'] == 'xyz'

I was thinking of just attaching that to app. Then you can do app.config or if you don't know the current application you can do current_app.config.

As long as I can use current_app to avoid circular dependencies that should work fine.

Another thing to consider is the ability to override the default configuration easily in unit tests, where you want to use a test database and other safe settings.

There is now a branch for this: http://github.com/mitsuhiko/flask/tree/config-support

Outstanding issues:

1. Configuration keys not documented
2. Unsure about where and how to document that
3. Document config keys as SECRET_KEY or secret_key?

Implemented :)
