What is the best way to update the key for the sorting field in a meteor collection query?

Question

I am struggling to replace the name key with a value passed in via a parameter this.params.sortby in the code below. Any help would be appreciated.

For example, if:

this.params.sortby=location

I would like the following:

Template.MyTemplate.helpers({
    data: function () {
      return MyCollection.find({},{sort:{name: 1 }});
    }
  });

To be changed to this:

Template.MyTemplate.helpers({
    data: function () {
      return MyCollection.find({},{sort:{location: 1 }});
    }
  });

If you need to dynamically name keys in an object, you can achieve this using the bracket notation. Here's an example:

var dynamicObject = {};
dynamicObject[this.userInput.dynamicKey] = 'some value';

For instance, if this.userInput.dynamicKey is set to "category", your dynamicObject will look like this:

var dynamicObject = {
  category: 'some value'
};

You can then use this object to sort your data accordingly:

MyData.find({}, {sort: dynamicObject});

Create a specialized SORT factory constructor to produce sorting standards prior to executing the query.
