This module defines the ErrorUI class, which is responsible for rendering error messages and generating corresponding user interface elements, such as inline keyboards.

ErrorUI Class

The ErrorUI class provides methods to construct a ViewResultDTO based on an error configuration, allowing for dynamic display of error messages to the user.

render_error Method

def render_error(self, error_config: dict) -> ViewResultDTO:

Renders an error message and an inline keyboard based on the provided error_config.

• error_config (dict): A dictionary containing configuration for the error message, which may include:
  • "title" (str): The title of the error (default: “Error”).
  • "text" (str): The main body of the error message (default: “Unknown error”).
  • "button_text" (str): The text for the inline button (default: “OK”).
  • "action" (str): The callback data for the inline button (default: “refresh”). This can be a simple callback or a navigation command (e.g., “nav:home”).

Process:

1. Extracts title, text, button_text, and action from the error_config, using default values if not provided.
2. Constructs the full message text by formatting the title and text.
3. Creates an InlineKeyboardBuilder and adds a button with the specified button_text and action as callback_data.
4. Returns a ViewResultDTO containing the formatted text and the generated inline keyboard markup.

Returns: A ViewResultDTO object ready to be sent to the user.
