## Forbid Extra Form Fields { #forbid-extra-form-fields }

In some special use cases (probably not very common), you might want to **restrict** the form fields to only those declared in the Pydantic model. And **forbid** any **extra** fields.

/// note

This is supported since FastAPI version `0.114.0`. 🤓

///

The `HeroUpdate` *data model* is somewhat special, it has **all the same fields** that would be needed to create a new hero, but all the fields are **optional** (they all have a default value). This way, when you update a hero, you can send just the fields that you want to update.

Because all the **fields actually change** (the type now includes `None` and they now have a default value of `None`), we need to **re-declare** them.

        // Verify all fields through reflection
        Field field = response.getClass().getSuperclass().getSuperclass().getDeclaredField("totalParameterCount");
        field.setAccessible(true);
        assertEquals(totalParams, field.get(response));

        field = response.getClass().getSuperclass().getSuperclass().getDeclaredField("totalDataCount");
        field.setAccessible(true);

     * @param id the document ID to retrieve
     * @param fields the fields to include in the response (null for all fields)
     * @return the document as a map of field names to values, or null if not found
