Subclassing Flask ================= The :class:`~flask.Flask` class is designed for subclassing. For example, you may want to override how request parameters are handled to preserve their order:: from flask import Flask, Request from werkzeug.datastructures import ImmutableOrderedMultiDict class MyRequest(Request): """Request subclass to override request parameter storage""" parameter_storage_class = ImmutableOrderedMultiDict class MyFlask(Flask): """Flask subclass using the custom request class""" request_class = MyRequest This is the recommended approach for overriding or augmenting Flask's internal functionality.
