find('neighbors', $params)

'neighbors' will perform a find similar to 'first', but will return the row before and after the one you request. Below is a simple (controller code) example:

function some_function() {
   $neighbors = $this->Article->find('neighbors', array('fields' => 'id', 'value' => 3));
}

1. function some_function() {
2. $neighbors = $this->Article->find('neighbors', array('fields' => 'id', 'value' => 3));
3. }

You can see in this example the two required elements of the $params array: field and value. Other elements are still allowed as with any other find (e.g. if your model acts as containable, then you can specify 'contain' in $params). The format returned from a find('neighbors') call is in the form:

Array
(
    [prev] => Array
        (
            [ModelName] => Array
                (
                    [id] => 2
                    [field1] => value1
                    [field2] => value2
                    ...
                )
            [AssociatedModelName] => Array
                (
                    [id] => 151
                    [field1] => value1
                    [field2] => value2
                    ...
                )
        )
    [next] => Array
        (
            [ModelName] => Array
                (
                    [id] => 4
                    [field1] => value1
                    [field2] => value2
                    ...
                )
            [AssociatedModelName] => Array
                (
                    [id] => 122
                    [field1] => value1
                    [field2] => value2
                    ...
                )
        )
)

Note how the result always contains only two root elements: prev and next.
