Fonction get_flashed_messages - module flask

Signature de la fonction get_flashed_messages

def get_flashed_messages(with_categories: 'bool' = False, category_filter: 't.Iterable[str]' = ()) -> 'list[str] | list[tuple[str, str]]' 

Description

help(flask.get_flashed_messages)

Pulls all flashed messages from the session and returns them.
Further calls in the same request to the function will return
the same messages.  By default just the messages are returned,
but when `with_categories` is set to ``True``, the return value will
be a list of tuples in the form ``(category, message)`` instead.

Filter the flashed messages to one or more categories by providing those
categories in `category_filter`.  This allows rendering categories in
separate html blocks.  The `with_categories` and `category_filter`
arguments are distinct:

* `with_categories` controls whether categories are returned with message
  text (``True`` gives a tuple, where ``False`` gives just the message text).
* `category_filter` filters the messages down to only those matching the
  provided categories.

See :doc:`/patterns/flashing` for examples.

.. versionchanged:: 0.3
   `with_categories` parameter added.

.. versionchanged:: 0.9
    `category_filter` parameter added.

:param with_categories: set to ``True`` to also receive categories.
:param category_filter: filter of categories to limit return values.  Only
                        categories in the list will be returned.
