"MongoDB append to document array (moved from Getting Started section)"

mrmikev

I'm attempting to add an item to an array within a document in MongoDB. For example, here's the initial document.

{
"_id" : ObjectId("55bfa1619b527d2ffb37439e"),
"modelName": "Model Sample A1",
"modelResults" : [
{
"resultID" : "1",
"name" : "Result 1 Name",
"resultStuff" : "1000"
},
{
"resultID" : "2",
"name" : "Result 2 Name",
"resultStuff" : "2000"
},
{
"resultID" : "3",
"name" : "Result 3 Name",
"resultStuff" : "3000"
},
{
"resultID" : "4",
"name" : "Result 4 Name",
"resultStuff" : "4000"
}
]
}

I want to add this item to the modelResults array:

{
"resultID" : "6",
"name" : "Result 6 Name",
"resultStuff" : "6000"
}

The command in MongoDB (outside of RapidMiner) would be:

db.mvstuff.update({modelName:"Model Sample A1"},{$push : {modelResults : {
"resultID" : "6",
"name" : "Result 6 Name",
"resultStuff" : "6000"
} }})

I want the result to look like this without having to read in the entire modelResults array and append the new item to it in RapidMiner and write the entire modelResults array back to MongoDB.:

{
"_id" : ObjectId("55bfa1619b527d2ffb37439e"),
"modelName": "Model Sample A1",
"modelResults" : [
{
"resultID" : "1",
"name" : "Result 1 Name",
"resultStuff" : "1000"
},
{
"resultID" : "2",
"name" : "Result 2 Name",
"resultStuff" : "2000"
},
{
"resultID" : "3",
"name" : "Result 3 Name",
"resultStuff" : "3000"
},
{
"resultID" : "4",
"name" : "Result 4 Name",
"resultStuff" : "4000"
},
{
"resultID" : "6",
"name" : "Result 6 Name",
"resultStuff" : "6000"
}
]
}

Here's an example process, but I've not been able to get the desired results:

Thanks for your help and comments!
