Struct TicketByID 

pub struct TicketByID {
    _marker: PhantomData<()>,
    function_component: FunctionComponent<Self>,
}

A component for displaying, updating, and deleting a single ticket by its ID.

This component fetches a specific ticket’s details from the backend based on the id provided in its TicketProps. It allows administrators to update the ticket’s status and delete the ticket.

Props

• id: The i32 ID of the ticket to fetch and display.

State

Uses use_state hooks to manage:

• ticket: The fetched Ticket data, if available.
• error: Any error message encountered during API calls.
• loading: A boolean indicating if data is currently being fetched.
• status: The selected status for updating the ticket.
• deleting: A boolean indicating if a delete operation is in progress.
• delete_error: Any error message from a delete operation.

Functionality

• Data Fetching: On component mount or id change, fetches ticket data from /api/tickets/:id.
• Status Update: Provides a dropdown to change the ticket’s status. Submitting the form sends a PATCH request to /api/tickets/:id with a TicketUpdateScheme payload.
• Ticket Deletion: Includes a “Delete” button that, after user confirmation, sends a DELETE request to /api/tickets/:id. On success, clears the ticket from display.
• Error Handling: Displays error messages for network issues, API errors, or parsing failures.
• Date Formatting: Displays the ticket creation date formatted to Europe/Berlin timezone.

html! {
    <TicketByID id={123} />
