Clone object in array to add as new element

[Chris Mcvittie]

Hi, 

I've an object with an array of schemas.  

e.g.

Address= new Schema(

  Line 1: String

)

Person = new Schema(

  Addresses: [Address]

)

I have a case where I want to clone the last address and add it to the Addresses array.

addr = _.clone(_.last(p.Addresses))

p.Addresses.push(addr)

p.save(...)

but I'm getting the error below when I try to save.

TypeError: Object function toString() { [native code] } has no method 'cast'" 

Is there a better way to do this in mongoose?

Thanks, 

Chris

Hi Chris, this is just a guess, but rather than cloning, you might try the casting the document to an ordinary object with the toObject() method, then new up a fresh document based on that object.  Again -- just a guess.
