There are some cases where you might need to convert a data type (like a Pydantic model) to something compatible with JSON (like a `dict`, `list`, etc).

For example, if you need to store it in a database.

For that, **FastAPI** provides a `jsonable_encoder()` function.

## Using the `jsonable_encoder` { #using-the-jsonable-encoder }

        validate(form, messages -> {}, this::asEditHtml);
        verifyToken(this::asEditHtml);
        getKeyMatch(form).ifPresent(entity -> {
            try {
                keyMatchService.store(entity);
                saveInfo(messages -> messages.addSuccessCrudCreateCrudTable(GLOBAL));
                ComponentUtil.getKeyMatchHelper().update();
            } catch (final Exception e) {

    }
    this.table = newDelegate;
    this.entries = null;
    this.keys = null;
    this.values = null;
    incrementModCount();
    return newDelegate;
  }

  /** Stores the hash table mask as the number of bits needed to represent an index. */
  private void setHashTableMask(int mask) {
    int hashTableBits = Integer.SIZE - Integer.numberOfLeadingZeros(mask);
    metadata =

The drives should all be of approximately the same size.

* The **database model** would probably need to have a hashed password.

Never store user's plaintext passwords. Always store a "secure hash" that you can then verify.

If you don't know, you will learn what a "password hash" is in the [security chapters](security/simple-oauth2.md#password-hashing){.internal-link target=_blank}.
