But How Can You Complain When You Do Nothing?

You may have noticed some "bad" data being displayed in the HTML table in the previous installments of this series. Now, we will filter the query to ignore empty documents, and order by Year Arrived and then Year Departed (yearin and yearout)

To do so, replace the previous MongoDB query code:

Template.placesLived.helpers({
 	places: function () {
        // this helper returns a cursor of all of the documents in the collection
        return TimeAndSpace.find();
    }
});

...with this:

Template.placesLived.helpers({
 	places: function () {
        // this helper returns a cursor of all of the documents in the collection
	    return TimeAndSpace.find(
			{ts_city: {$exists: true, $ne: ""}, ts_state: {$exists: true, $ne: ""}},
			{sort: {ts_yearin: 1, ts_yearout: 1}}
		);
});

That's Because He was Wearing a Bullet-proof Vest!

Ain't that grand! Here is what the filtered and ordered collection looks like now:

The duplicates are still there; removing one of them is an exercise left to the reader (don't look at me), as is any baroquing or gingerbreading such as adding a map, with a pushpin for each location, perhaps numbered or with some other indication on it, such as certain colors to indicate duration of time spent in that spot, etc.

In the next and final installment of "As the Meteor Blazes", I will provide you with a plethora of poignant points and programatically lucrative links.
