That's what we'll solve, let's load the model before the requests are handled, but only right before the application starts receiving requests, not while  the code is being loaded.

## Lifespan { #lifespan }

        // Document list size should remain the same
        assertEquals(1, result.getDocumentList().size());
    }

    public void test_multipleBuilds() {
        // Test that each builder creates independent results
        // Create first result with one document
        SearchResult.SearchResultBuilder builder1 = SearchResult.create();
        Map<String, Object> doc1 = new HashMap<>();
        doc1.put("id", "1");

   *       correctly, including surrogate character pairs. If the input is badly formed the escaper
   *       should throw {@link IllegalArgumentException}.
   *   <li>{@link CharEscaper} handles Java characters independently and does not verify the input
   *       for well formed characters. A {@code CharEscaper} should not be used in situations where
   *       input is not guaranteed to be restricted to the Basic Multilingual Plane (BMP).

        // Create a copy
        DataStoreParams copy = dataStoreParams.newInstance();

        // Modify original
        dataStoreParams.put("key5", "value5");

        // Verify copy is independent
        assertTrue(dataStoreParams.containsKey("key5"));
        assertFalse(copy.containsKey("key5"));

        // Get as map and verify
        Map<String, Object> map = dataStoreParams.asMap();

Now let's go back a bit and understand what is all that.

The `password` "flow" is one of the ways ("flows") defined in OAuth2, to handle security and authentication.

OAuth2 was designed so that the backend or API could be independent of the server that authenticates the user.

But in this case, the same **FastAPI** application will handle the API and the authentication.

So, let's review it from that simplified point of view:

        assertNotNull(results);
    }

    @Test
    public void testMultipleConverterInstances() throws IOException {
        // Test that multiple converter instances work independently
        AnalyzerConverter converter1 = new AnalyzerConverter(client, settings);
        AnalyzerConverter converter2 = new AnalyzerConverter(client, settings);

        String text = "test";

Eso es lo que resolveremos, vamos a cargar el modelo antes de que los requests sean manejados, pero solo justo antes de que la aplicación comience a recibir requests, no mientras el código se está cargando.

* Hashage de **mots de passe sécurisé** par défaut.
* Authentification par **jetons JWT**.
* Modèles **SQLAlchemy** (indépendants des extensions Flask, afin qu'ils puissent être utilisés directement avec des *workers* Celery).
* Modèle de démarrages basiques pour les utilisateurs (à modifier et supprimer au besoin).
* Migrations **Alembic**.
