Query condition in populate

[Sergey]

Hi!

I am using version 2.3.6

I am trying to use the query conditions in populate method, but I am facing the issue described in https://github.com/LearnBoost/mongoose/pull/553

namely, if a condition is used then still all the records are populated but ones that don't satisfy the condition have the populated field is set to null, i.e. if I use the same schemas as in https://groups.google.com/forum/#!topic/mongoose-orm/A8qAGxihF3o and perform a query like:

var query = BookModel.find();

query.populate('author','name',{name:'author1'});

query.find(function(err,books){

  console.log(books);

    process.exit(0);

});

Then the output is:

[  { author: { _id: 4ea0db52e09aa6aad2e831fe, name: 'author1' },

    title: 'book1',

    _id: 4ea0dbebc191848704000005 },

  { author: null,

    title: 'book2',

    _id: 4ea0dbebc191848704000006 } ,

  { author: null,

    title: 'book3',

    _id: 4ea0dbebc191848704000007 } ,

  { author: null,

    title: 'book4',

    _id: 4ea0dbebc191848704000008 } ]

However, I expect only the 1st record in the output result. As you mentioned in https://github.com/LearnBoost/mongoose/pull/553

It seems that you have fixed that, but the fix is not in the 2.3.6 release..could you tell me how I can get the fix?

This is different than what was discuessed in pull 553 which was about a document with a child array of ObjectIds and populating them. You have an array of documents and are populating one subproperty on each. If the document is not found, null is returned.

So, are you saying that the behavior I observe is correct?
