How to use Meteor Upsert

Question

Having a bit of trouble getting my Meteor upsert function working. I am fairly (200 lines of code) new, and I'm having a bit of trouble.

The collection keeps on having additional rows inserted, rather than just updating. I spend the past 30 minutes googling, but I can't find any examples I can understand.

Here's my code:

Values.upsert(     {       // Selector       source: "SourceOne",       currency: "USD"     },     {       // Modifier       value: res.data['data']['last']['value'],       time: Date.now(),     }   ); 

I've also tried

if(Values.find(       {},{fields: {'source':"SourceOne", 'currency': "USD"}}     )) {     Values.update(       {         source: "SourceOne",          currency: "USD"       },       {         value: res.data['data']['last']['value'],         time: Date.now()       }     );   } else {     console.log('blah');     Values.insert({       source: "SourceOne",        currency: "USD",       value: res.data['data']['last']['value'],       time: Date.now()     });   } 

And still can't seem to figure it out.

Answer 1

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     } });
