///

By using a `with` block, we make sure that the file-like object is closed after the generator function (the function with `yield`) is done. So, after it finishes sending the response.

It wouldn't be that important in this specific example because it's a fake in-memory file (with `io.BytesIO`), but with a real file, it would be important to make sure the file is closed after the work with it is done.

### Files and Async { #files-and-async }

# Background Tasks { #background-tasks }

You can define background tasks to be run *after* returning a response.

This is useful for operations that need to happen after a request, but that the client doesn't really have to be waiting for the operation to complete before receiving the response.

This includes, for example:

* Email notifications sent after performing an action:

		t.Errorf("No error should happen, but got %v", err)
	}

	DB.Migrator().DropTable("log_usage")

	if err := DB.Exec(`
CREATE TABLE public.log_usage (
    log_id bigint NOT NULL
);

ALTER TABLE public.log_usage ALTER COLUMN log_id ADD GENERATED BY DEFAULT AS IDENTITY (
    SEQUENCE NAME public.log_usage_log_id_seq
    START WITH 1
    INCREMENT BY 1
    NO MINVALUE
    NO MAXVALUE
    CACHE 1
);

        // Test with meta parameters
        configParameters = "field.meta.author=author\nfield.meta.date=date";
        result = ParameterUtil.createConfigParameterMap(configParameters);
        assertEquals(2, result.get(ConfigName.META).size());
        assertEquals("author", result.get(ConfigName.META).get("author"));
        assertEquals("date", result.get(ConfigName.META).get("date"));

        t.setMechanismToken(null);
        t.setMechanismListMIC(null);
        assertNull(t.getMechanismToken(), "mechanismToken should be null after setting null");
        assertNull(t.getMechanismListMIC(), "mechanismListMIC should be null after setting null");
    }
