|
|
app-related functions that can be registered on a real application
|

|
later.
|
||
|
|
|
||
|
|
A blueprint is an object that allows defining application functions
|
||
|
|
without requiring an application object ahead of time. It uses the
|
||
|
|
same decorators as :class:`~flask.Flask`, but defers the need for an
|
||
|
|
application by recording them for later registration.
|
||
|
|
|
||
|
|
Decorating a function with a blueprint creates a deferred function
|
||
|
|
that is called with :class:`~flask.blueprints.BlueprintSetupState`
|
||
|
|
when the blueprint is registered on an application.
|
||
|
|
|
||
|
|
See :doc:`/blueprints` for more information.
|
||
|
|
|
||
|
|
:param name: The name of the blueprint. Will be prepended to each
|
||
|
|
endpoint name.
|
||
|
|
:param import_name: The name of the blueprint package, usually
|
||
|
|
``__name__``. This helps locate the ``root_path`` for the
|
||
|
|
blueprint.
|
||
|
|
:param static_folder: A folder with static files that should be
|
||
|
|
served by the blueprint's static route. The path is relative to
|
||
|
|
the blueprint's root path. Blueprint static files are disabled
|
||
|
|
by default.
|
||
|
|
:param static_url_path: The url to serve static files from.
|
||
|
|
Defaults to ``static_folder``. If the blueprint does not have
|
||
|
|
a ``url_prefix``, the app's static route will take precedence,
|
||
|
|
and the blueprint's static files won't be accessible.
|
||
|
|
:param template_folder: A folder with templates that should be added
|
||
|
|
to the app's template search path. The path is relative to the
|
||
|
|
blueprint's root path. Blueprint templates are disabled by
|
||
|
|
default. Blueprint templates have a lower precedence than those
|
||
|
|
in the app's templates folder.
|
||
|
|
:param url_prefix: A path to prepend to all of the blueprint's URLs,
|
||
|
|
to make them distinct from the rest of the app's routes.
|
||
|
|
:param subdomain: A subdomain that blueprint routes will match on by
|
||
|
|
default.
|
||
|
|
:param url_defaults: A dict of default values that blueprint routes
|
||
|
|
will receive by default.
|
||
|
|
:param root_path: By default, the blueprint will automatically set
|
||
|
|
this based on ``import_name``. In certain situations this
|
||
|
|
automatic detection can fail, so the path can be specified
|
||
|
|
manually instead.
