## Criar o App com um Único Modelo

Vamos criar a primeira versão mais simples do app com um único modelo **SQLModel**.

Depois, vamos melhorá-lo aumentando a segurança e versatilidade com **múltiplos modelos** abaixo. 🤓

### Criar Modelos

Importe o `SQLModel` e crie um modelo de banco de dados:

     *
     * @param crudMode the CRUD mode
     * @param id the file configuration ID
     * @return HTML response for the details page
     */
    @Execute
    @Secured({ ROLE, ROLE + VIEW })
    public HtmlResponse details(final int crudMode, final String id) {
        verifyCrudMode(crudMode, CrudMode.DETAILS);
        saveToken();

     *
     * @param crudMode the CRUD mode
     * @param id the label type ID
     * @return HTML response for the details page
     */
    @Execute
    @Secured({ ROLE, ROLE + VIEW })
    public HtmlResponse details(final int crudMode, final String id) {
        verifyCrudMode(crudMode, CrudMode.DETAILS);
        saveToken();

Alle diese Parameter können anders als "`static`" lauten, passen Sie sie an die Bedürfnisse und spezifischen Details Ihrer eigenen Anwendung an.

## Weitere Informationen

     *
     * @param crudMode the CRUD operation mode
     * @param id the ID of the path mapping to display
     * @return HTML response for the path mapping details page
     */
    @Execute
    @Secured({ ROLE, ROLE + VIEW })
    public HtmlResponse details(final int crudMode, final String id) {
        verifyCrudMode(crudMode, CrudMode.DETAILS);
        saveToken();

```

And because you are using `StaticFiles`, that CSS file would be served automatically by your **FastAPI** application at the URL `/static/styles.css`.

## Validation de données

Si vous allez sur <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>, vous aurez une belle erreur HTTP :

```JSON

            ],
