Description:
 def static_url(self, path: str, include_host: bool = None, **kwargs: Any) -> str: """Returns a static URL for the given relative static file path. This method requires you set the ``static_path`` setting in your application (which specifies the root directory of your static files). This method returns a versioned url (by default appending ``?v=<signature>``), which allows the static files to be cached indefinitely. This can be disabled by passing ``include_version=False`` (in the default implementation; other static file implementations are not required to support this, but they may support other options). By default this method returns URLs relative to the current host, but if ``include_host`` is true the URL returned will be absolute. If this handler has an ``include_host`` attribute, that value will be used as the default for all `static_url` calls that do not pass ``include_host`` as a keyword argument. """
