Correct way to update and handle input values in custom function

[kcfgl]

First of all, awesome library so thank you. I'm struggling just a bit however and likely doing something dumb.

Part of my final query will need to do an $elemMatch. I didn't see this option in the docs so I figured custom function. The final structure of this piece of the mongo query should be: place_amentities: {'$elemMatch': {lounge: 1, restrooms: 1}}

The params in the URL would be ?pa=lounge,restrooms

Pretty straightforward custom function: pa: function(query, input) { const amentitiesArr = input.split(',').map(a => a +':'+1); query['place_amentities'] = { $elemMatch: amentitiesArr }; }

The issue I'm having is that final output looks like this: place_amentities: { '$elemMatch': [ 'lounge:1', 'restrooms:1'] }

Instead of this: place_amentities: { '$elemMatch': { lounge: 1, restrooms: 1} }

Everything seems to be a string. The core library doesn't do that though, everything is created exactly as Mongo would expect it, so I'm sure I'm just screwing up something simple in the custom function.

Thanks for any help you can provide. I know this isn't an "issue" but maybe others have run into the same question.

Try the following:

pa: function(query, input) { 
  const amentitiesArr = input.split(',').map(a => { [a]: 1 }); 
  query['place_amentities'] = { $elemMatch: amentitiesArr }; }
}
