A configuration method involves directing a Flask application to retrieve its settings from a Python object. This object, typically a class or module, contains attributes representing configuration variables. For example, a class might define attributes such as `DEBUG = True`, `SECRET_KEY = ‘a_secret_key’`, and `DATABASE_URI = ‘sqlite:///:memory:’`. Invoking a specific method within the Flask application, providing the name of this configuration object, then loads these attributes as configuration parameters.
This approach promotes modularity and organization within Flask projects. It allows for the separation of configuration concerns from the main application logic. Different configuration objects can be used for development, testing, and production environments, enabling environment-specific settings to be easily applied. Historically, this method has provided a structured way to manage and switch between varying sets of application parameters without altering the core application code.
