表数据网关，级联一对多和Zend

Question

I am new to Zend Framework and OO design patterns.

I have three tables: Owners, Shops and Products. One Owner has many Shops; and each Shop has many Products.

I have extended Zend's DB Table Abstract for each of the three tables, and setup dependent tables and reference maps.

If I want to find which Products are available from a particular Owner, I start with an Owner object and use findDependentRowset to get a rowset of Shops. I then iterate the rowset to find all Products (again using findeDependentRowset).

Is there a shortcut for doing this? How do you go about navigating three such tables using the Table Data and Row Data Gateway patterns? (Or should I be moving to a Data Mapper perhaps?)

Thanks for your thoughts!

Answer 1

I think what you can use is findManyToManyRowset method.

For example to find produces for a given owner you could be able do:

$productsRowset = $ownerRow->findManyToManyRowset('Products_Table_Model','Shops_Table_Model');
