What is the best way to validate data in mongo?

Question

What\'s the best way to validate data being inserted or updated into MongoDB? Is it to write some sort of server executed Javascript code that does the validation?

Answer 1

I've just started using MongoDB and PHP together, inside a Zend Framework based application.

I have created 1 object for each MongoDB collection (e.g. User.php maps to the user collection). Each object knows what collection it maps to, and what fields are required. It also knows which filters (Zend_Filter_Input) and validators (Zend_Validate) should be applied to each field. Before doing a MongoDB insert() or save(), I run $object->isValid(), which executes all the validators. If they all pass isValid() will return true, and I proceed to run the insert() or save(), otherwise I display the errors.
