    // Test offer with valid generator
    public void test_offer_withValidGenerator() {
        TestThumbnailGenerator generator = new TestThumbnailGenerator();
        generator.available = true;
        generator.target = true;
        generator.task = new Tuple3<>("generator1", "docid1", "path1");
        thumbnailManager.add(generator);

        Map<String, Object> docMap = new HashMap<>();
        docMap.put("_id", "docid1");

Aqui veremos um exemplo usando <a href="https://sqlmodel.tiangolo.com/" class="external-link" target="_blank">SQLModel</a>.

**SQLModel** é construído sobre <a href="https://www.sqlalchemy.org/" class="external-link" target="_blank">SQLAlchemy</a> e Pydantic. Ele foi criado pelo mesmo autor do **FastAPI** para ser o par perfeito para aplicações **FastAPI** que precisam usar **bancos de dados SQL**.
