Invalid Object ID when deleting document with MongoDB

I am having a problem deleting a document in the ORM using MongoDB. I am getting "Invalid object ID " error when the document I am deleting is the result of a find(). Can anyone point out what I am missing?

TIA

here is the code

//database

> db.token.find();

Try using a MongoId instead of an id as string:

$arr = array( 'conditions' => array('_id' => new MongoId($token)));

Thanks for the reply.

I think I see this may be an issue with the Mongo ORM. But, I am not sure that the problem is with Phalcon or the PECL::MongoDB library.

I think there is a couple of things I left out: I am using custom _id values This is a small existing ZF2 app that uses the PECL::MongoDB libraries.

As to your reply: First I don't understand how setting the type of the _id value to MongoId in the query would affect the _id in the return set. I think you should be able to query on any field and call delete or am I misunderstanding the docs?

But I did find out that calling new MongoId('any string that is not 24 hex characters') with the PECL::MongoDB library throws an "Invalid Object Id" exception. This happens for 1.4.1 and with 1.3.3 it will just generate a ObjectId Object with different value.

So I am thinking that when I call ->delete() on the result object somewhere in the ORM it is converting the value of _id to an ObjectId hence giving me the error.

If am right.

How can I use the ORM with custom ids?

Yes that is it. Sorry for asking a simple question in a complicated way.
