Iron Router parameter returns no results

Question

I'm trying to use a parameter in Iron Router. My url is /activity/dJW9PWJEmSqT3bbSA.

Here's what I have so far:

Router.route('/activity/:_id', function() {
  var params = this.params;
  console.log(params);
  var activityID = params._id;
  var currentActivity = Activities.findOne({_id: this.activityID});
  this.layout('fullScreen', {
    data: {
      activity: currentActivity,
      activityStarted: false
    }
  });
  this.render('activityDetail');
});

console.log(params) returns [] (0). I'm not sure why.

Any insight would be greatly appreciated.

Try this:

Router.route('/activity/:_id', function() {
    this.render('activityDetail',{
        data: function(){
            return Activities.findOne({_id: this.params._id})
        }
    });
});
