This is my application structure, and every time i try to access the routes with blueprints i get this error:
return self.view_functionsrule.endpoint TypeError: get() missing 1 required positional argument: 'self'
The routes are in this format : api.add_resource(TrayResource, '/tray', '/trays') api.add_resource(RackResource, '/rack', '/racks')
Should i add the blueprints and register them in the init file ad well?
Hello, Do you mind sharing the code in TrayResource or RackResource?

If you are using Flask-Restful then you don't need to use blueprints. Also, remove this @tray_bp.route('/tray') line from your resource methods. For further questions, I'd suggest asking your question here or posting the question on stackoverflow.
@tray_bp.route('/tray')
Thanks
