Meteor transform and sorting

help
1

Hello !

I have a little problem to transform a collection and sorting the data from.

I have a basic test Collection
{
{_id:1,name:“a”},
{_id:2,name:“c”},
{_id:3,name:“b”},
}

/server and client side/
var test = new Mongo.Collection(“test”);

/server side/
Meteor.publish(“test”,function(){
return test.find({},{sort:{name:1});
})

/client side/
Meteor.susbcribe(‘test’);

I sort in asc order ‘a,c,b’ so the result is -> ‘a,b,c’

Ok for this.
But if i want to transform the collection doc like this ->
test = new Mongo.Collection(“test”, {
transform: function (doc) {
if (doc.name == “b”) {
doc.name = “z”;
}
return doc;
}
});

The result is -> 'a,z,c’
In fact, the doc ‘b’ has well been replace by ‘z’, but the sort option is not updated so…

I want to transform field name ‘b’ by ‘z’ to have this sort result : ‘a,c,z’

Than’s a lot for your help.

Ok i have found solution ->

Meteor.publish(‘test’, function () {
var self = this;
var result = test.find({}, {
sort: {
name: -1
}
})

result.observe({
    added: function (doc) {
        if(doc.name=="b"){
            doc.name="z"
        }
        self.added('test',doc._id,doc);
        return doc;
    }
});
return result;

});
