Next, let’s create a hook that will run before each request to post a message. Add this method below the definition of ALLOWED_IMAGE_TYPES: def validate_image_type(req, resp to an entire resource by simply decorating the class: @falcon.before(extract_project_id) class Message: pass Similar logic can be applied globally with middleware.
