Meteor Methods insert not working (mongodb) - mongodb

Question

I am trying to write a table with various numbers of rows and columns to a database. For this, I have a Criterion collection that saves the table headers and an Option collection that saves the table data.
The structure is like this:
for Criterion:
{
{ "_id" : "hId1", "name" : "Option Name", "tableId" : "tId1" },
{ "_id" : "hId2", "name" : "Rent", "score" : 9, "tableId" : "tId1" },
{ "_id" : "hId3", "name" : "Surface", "score" : 5, "tableId" : "tId1" },
{ "_id" : "hId4", "name" : "Price", "score" : 5, "tableId" : "tId1" },
{ "_id" : "hId5", "name" : "CPU", "score" : 5, "tableId" : "tId4" }
etc.
}
for Option:
{
{ "_id" : "id1", "score" : 5,
"hId1" : { "value" : "Apt 1" },
"hId2" : { "value" : "800 sqft", "score" : 1 },
"hId3" : { "value" : "$800", "score" : 3 },
etc.
"tableId" : "tId1"
}
{ "_id" : "id2", "score" : 5,
"hId1" : { "value" : "Apt 2" },
"hId2" : { "value" : "780 sqft", "score" : 10 },
"hId3" : { "value" : "$700", "score" : 3 },
etc.
"tableId" : "tId1"
}
etc.
}
The first row for Criterion will always have "Option Name". For the data above, the table with "tableId" = "tId1" would end up looking like this (tableId and headerId are the keys):
| Option Name | Surface | Price |
| =========== | ======== | ===== |
| Apt 1 | 800 sqft | $800 |
| Apt 2 | 780 sqft | $700 |
My code looks like this (imports/api/comparison.js):
/**
* Options are for the rows
*/
export var Option = new Mongo.Collection('option');
/**
* Criteria are the columns
*/
export var Criterion = new Mongo.Collection('criterion');
Meteor.methods({
'comparison.insertRow' (query, headerId, tableId, isFirst) {
check(query, Object);
check(headerId, String);
check(tableId, String);
check(isFirst, Boolean);
if(isFirst){
var data = {};
data._id = headerId;
data.tableId = tableId;
data.name = "Option Name";
Criterion.insert(data);
}
query._id = tableId;
Option.insert(query);
},
});
Where isFirst is a boolean expressing whether this is the first row in a table or not.
My query is constructed like this (imports/ui/Menu/DataInsert.jsx):
var query = {};
query.score = // value
// get the header separately
query[headerId] = {
value: //valueH from form
};
// Find the text field via the React ref
for (var i = 1, len = cols.length; i < len; i++) {
query[cols[i]._id] = {
value: //valueV from form,
score: //valueS from form
};
}
My files are available on the server because I am doing this in server/main.js: import '../imports/api/comparison.js';
The query gets inserted no problem into Option no problem.
Why isn't data getting inserted into Criterion (when isFirst = true)?
I did a console.log(data) and a console.log(query) and it looks like this:
whereas the data in the db looks like this:

#jordanwillis was correct above, this was happening because I was setting the _id manually on the query. I did need to set the id, but I needed to set the tableId.
So, for the record, this is what I did:
'comparison.insertRow' (query, headerId, tableId, isFirst) {
check(query, Object);
check(headerId, String);
check(tableId, String);
check(isFirst, Boolean);
if(isFirst){
var data = {};
data._id = headerId;
data.tableId = tableId;
data.name = "Option Name";
Criterion.insert(data);
}
query.tableId = tableId;
Option.insert(query);
},
And my foreign keys are tableId and headerId (which is part of query).
