Searching for a specific collection item based on a custom property (excluding _id) in Meteor - what's the best approach?

I am facing an issue with my application that utilizes Flow Router along with its pub/sub functionality. I have set up a collection and template helpers. The code works fine on the client side.

Template.theCase.helpers({
    theCase: function () {
        var id = FlowRouter.getParam('id');
        var theCase = Cases.findOne({
            id: id
        });

        return theCase;
    }
});

and

{{#with theCase}}
  {{ id }}
{{/with}}

On the server side, I have the following code:

Meteor.publish('theCase', function (id) {
    return Cases.findOne({
        id: id
    });
});

And in the shared (lib) code:

FlowRouter.route('/case/:id', {
    subscriptions: function (params) {
        this.register('theCase', Meteor.subscribe('theCase', params.id));
    },
    action: function (params, queryParams) {
        return BlazeLayout.render('container');
    }
});

The issue I am encountering is that the helper function is returning undefined because it is unable to find items in the collection based on any property other than _id. I have gone through the official documentation on pub/sub, helpers, and routing but have not been able to find a solution. Can anyone provide any suggestions?

Answer №1

When querying, you have the flexibility to search by any field. However, if the helper returns undefined, it means that no matching results were found.

The following code snippet presents an issue:

Meteor.publish('theCase', function (id) {
    return Cases.findOne({
        id: id
    });
});

To address this problem, the code should be modified to: return Cases.find({id: id});

Keep in mind that publications need to either return a cursor or invoke this.ready().
