Error occurred while attempting to fetch the associated objects from the Parse.Query

I'm running into an issue with Parse.Query and how to handle the result promise. Here's my current code snippet:

var ga = new Parse.Query(Game);
ga.include('away_team');
ga.include('home_team');
ga.equalTo("objectId", req.params.id);
ga.find().then(function(result){
  console.log(result[0]);
});

The console log displays data like this:

{
  "home_team" : {"name":"Dallas Stars", "arena":"American Airlines Center"},
  "away_team" : {"name":"New York Rangers", "arena":"Madison Square Garden"},
  "createdAt" : "2015-12-28T10:35:35.541Z"
}

The challenge I'm facing is extracting the name from away_team within my promise function. When I attempt

console.log(results[0].away_team)
, it returns No message provided.

My desired output would be

{"name":"New York Rangers", "arena":"Madison Square Garden"}
. However, trying
console.log(results[0].away_team.name)
results in a TypeError.

In order to achieve my goal of displaying the correct title in my view based on the teams playing, I need access to the team names. For example:

res.render('inside/game', {
  title: result[0].away_team.name + " vs. " + result[0].home_team.name
  // title: New York Rangers vs. Dallas Stars
});

Is it possible to accomplish this within the routing class?

Answer №1

The outcome of the discovery is a parse object, not JSON. Your approach involves taking that object and converting it into plain JS objects via JSON text, which may not be ideal but does get the job done.

Since parse objects do not have explicitly defined methods for arbitrary keys, they cannot access most content directly. Instead, you must utilize the get function.

result[0].get("home_team")

You can then follow up with a request for the name, or save the result to a variable so that you can efficiently unpack multiple pieces of data.
