Converting a MongooseCollection into a normal array

[WilsonPage]

I want to be able to turn a Mongoose Collection into a normal array. I have heard there is a method .toArray(). I have tried calling this on the Mongoose Collection directly and on Model.find({}).toArray(function(err, docs) {}); Both seem to throw error 'has no method toArray()'. 

What am I doing wrong?

toArray() is a method of the drivers Cursor class. If I understand the question you can retrieve all docs in a collection by

YourModel.find({}, function (err, docs) {

  // docs is an array of all docs in collection

});

But the array returned still has all the hidden Mongoose methods and properties. I want to send this collection to the client and am currently having to do JSON.stringify(JSON.parse(docs)) to strip the array of all the Mongoose magic. Just wondering if there was a cleaner was of doing this?

You'll need to stringify() the data before sending. 

res.send(JSON.stringify(docs))

If just want to covert to vanilla js then call docs.toObject() directly.

Aaron, just so you know I found out today actually that an array of documents returned from a Model.find() actually has no toObject() method.  Only individual documents do.  I'm write now creating a workaround for this.  I'd like to submit this as a pull request, but I don't even know where to begin as far as putting it in the source.

[Aaron Heckmann]

oh right yeah thanks. there is no toObject method of the array returned from Model.find b/c its already a vanilla js array.

no need for a pull request. i don't want to subclass the array just to add toObject on it which would merely be

   return docs.map(function (d) { return d.toObject() })

True.  This is basically exactly what I did.
