Counting beans

In version 3.5 and higher you can count related beans like this:


    $numPages 
$book->countOwn('page');

This also works for shared lists:


    $numProjects 
$member->countShared('project');

And with conditions:


    $numProj 
$member
            
->withCondition(' member_project.role ', array('lead'))
            ->
countShared('project');

    
$numPages $book
            
->withCondition(' book_page.number > ? ', array(100))
            ->
countOwn('page');

The first line in the code block above counts all projects in which $member participates as a leader. The second example counts all pages in book $book after page number 100.
Relation counts also play nice with aliases and via:


    $shop
->via('relation')->countShared('customer');

    
$Andy->alias('coAuthor')->countOwn('book');

The first line in the code block above counts all customers for shop $shop using link type: relation. The second line counts all books written by Andy as a co-author.

Note that 'coAuthor' will be converted to co_author - the canonical name of the property.
