Flask-Whiteprint is an enhancement of Flask-Blueprint.
Flask-Whiteprint is on development. I recommend NOT using it now.
Flask-Whiteprint supports whiteprint-level error handler for all exceptions include 404 and 500. I'll remove that ending parentheses soon.
@blueprint.errorhandler() def handle_error(e): data = { 'error': { 'code': e.code, 'message': e.message } } return Response(data, mimetype='application/json', status=e.status)
You can alias url with alias
method. Alias redirects without any redirect response (e.g. 301 or 302) and with all request context (e.g. HTTP Header, URL Variables or Form Data). This code redirects /me
to /user/<int:id>
with all request context.
@api.route('/me', methods=['GET', 'POST', 'PUT', 'DELETE']) @api.route('/me/<path:path>', methods=['GET', 'POST', 'PUT', 'DELETE']) @login_required @jsoned def redirect_me(path=''): if 'path' in request.view_args: request.view_args.pop('path') user_path = '/user/%d/' % current_user.id + path if user_path[-1] == '/': user_path = user_path[:-1] return api.alias(user_path, current_user.id)
You can add child whiteprints to another whiteprint.
app (Flask Application) |-- api (Parent whiteprint) | |-- auth (Child whiteprint) | | |-- login (Another child whiteprint) | | `-- logout | |-- user | `-- post |-- web (Another parent whiteprint) | |-- auth | |-- user | `-- post `-- admin `-- admin
It looks awkward, but... just for an example!
