As code duplication increments the chances of bugs, security issues, code desynchronization issues (when you update in one place but not in the others), etc.

And these models are all sharing a lot of the data and duplicating attribute names and types.

We could do better.

We can declare a `UserBase` model that serves as a base for our other models. And then we can make subclasses of that model that inherit its attributes (type declarations, validation, etc).

    /**
     * Gets the default field for this query context.
     * @return The default field name, or null if not set.
     */
    public String getDefaultField() {
        return defaultField;
    }

    /**
     * Sets the default field for this query context.
     * @param defaultField The default field name to set.
     */
    public void setDefaultField(final String defaultField) {

     *
     * @return an {@link Optional} containing the project name to resume from, or empty if not specified
     */
    @Nonnull
    Optional<String> resumeFrom();

    /**
     * Returns the list of specified reactor projects to build instead of all projects.
     *
     * @return an {@link Optional} containing the list of project names to build, or empty if not specified
     */
    @Nonnull

This would mean that **FastAPI** would expect a body similar to:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

Again, doing just that declaration, with **FastAPI** you get:
