  def publish_article( config: ServerConfig, auth_manager: AuthManager, params: PublishArticleParams, ) -> ArticleResponse: """ Publish a knowledge article. Args: config: Server configuration. auth_manager: Authentication manager. params: Parameters for publishing the article. Returns: Response with the published article details. """ api_url = f"{config.api_url}/table/kb_knowledge/{params.article_id}" # Build request data data = { "workflow_state": params.workflow_state, } if params.workflow_version: data["workflow_version"] = params.workflow_version # Make request try: response = requests.patch( api_url, json=data, headers=auth_manager.get_headers(), timeout=config.timeout, ) response.raise_for_status() result = response.json().get("result", {}) return ArticleResponse( success=True, message="Article published successfully", article_id=params.article_id, article_title=result.get("short_description"), workflow_state=result.get("workflow_state"), ) except requests.RequestException as e: logger.error(f"Failed to publish article: {e}") return ArticleResponse( success=False, message=f"Failed to publish article: {str(e)}", )
