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.
