**FastAPI** will create the object of type `BackgroundTasks` for you and pass it as that parameter.

## Create a task function { #create-a-task-function }

Create a function to be run as the background task.

It is just a standard function that can receive parameters.

## Crear la App con un Solo Modelo { #create-the-app-with-a-single-model }

Primero crearemos la versión más simple de la aplicación con un solo modelo de **SQLModel**.

Más adelante la mejoraremos aumentando la seguridad y versatilidad con **múltiples modelos** a continuación. 🤓

### Crear Modelos { #create-models }

Importa `SQLModel` y crea un modelo de base de datos:

    //                                         -------------
    /**
     * Create a new char mapping item.
     * @param form The create form.
     * @return The HTML response.
     */
    @Execute
    @Secured({ ROLE })
    public HtmlResponse create(final CreateForm form) {
        verifyCrudMode(form.crudMode, CrudMode.CREATE, form.dictId);
        validate(form, messages -> {}, this::asEditHtml);
