## Declare model attributes { #declare-model-attributes }

You can then use `Field` with model attributes:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

`Field` works the same way as `Query`, `Path` and `Body`, it has all the same parameters, etc.

/// note | Technical Details

            final SearchRequestParams params, final OptionalThing<FessUserBean> userBean) {
        if (logger.isDebugEnabled()) {
            logger.debug("Sending query to main searcher: query={}", query);
        }
        final int pageSize = params.getPageSize();
        try {
            final SearchResult searchResult = searcher.search(query, params, userBean);

`Header` is a "sister" class of `Path`, `Query` and `Cookie`. It also inherits from the same common `Param` class.

But remember that when you import `Query`, `Path`, `Header`, and others from `fastapi`, those are actually functions that return special classes.

///

/// info

To declare headers, you need to use `Header`, because otherwise the parameters would be interpreted as query parameters.
