How to use Meteor Upsert

The collection keeps on having

Answer 2

Try this:

values.update({"id":id},
       { $set: {
          value: res.data['data']['last']['value'],
          time: Date.now() // no need coma here
      } },
      { upsert: true }
    );

Answer 3

Figured it out through trial and error:

Values.upsert({
    // Selector
    source: "SourceOne",
    currency: "USD"
}, {
    // Modifier
    $set: {
        value: res.data['data']['last']['value'],
        time: Date.now() // no comma needed here
    }
});

Answer 4

The above doesn't work for IDs. This works for me (with the same syntax as update):

Values.upsert(id,
{
  // Modifier
  $set: {
      value: res.data['data']['last']['value'],
      time: Date.now() // no need coma here
  }
}
);
