Adding a mongoDB array element using Python Eve

Background: (using Eve and Mongo)

I am working in Python using the Eve REST provider library connecting to mongoDB to pull out several REST endpoints from the database. I still managed to use Eve, but I ran into a problem that might be slightly higher than what Eve can do initially.

My problem is that in my mongoDb document format there is a field (called "slots") whose value is a list / array of dictionaries / embedded documents.

Thus, the structure of the mongoDB document:

{
   blah1: data1,
   blah2: data2,
   ...
   slots: [
       {thing1:data1, thing2:data2},
       {thingX:dataX, thingY:dataY}
   ]
}

I need to add new entries (IE add pre-filled dictionaries) to the list of slots.

pymongo, :

mongo.connection = MongoClient()
mongo.db = mongo.connection['myDB']
mongo.coll = mongo.db['myCollection']

...

mongo.coll.update({'_id' : document_id}, 
                  {'$push': { "slot" : {"thing1":"data1","thingX":"dataX"}  }  } )

REST action/URI, , POST to '_id/slots', . URI /app/012345678901234567890123/slots.
