Allow helpers with find(), not only findOne() about meteor-collection-helpers HOT 4 CLOSED

An example:

var opts = Statuses.find().getOptions(Session.get('currLang').code);

and

Statuses.helpers({
  getOptions: function(langCode) {
    return this.map(function(el) {
      return { id: el._id, name: el.name[langCode] };
    });
  }
});

from meteor-collection-helpers.

The helpers are on the documents returned by the find. So what you're looking for could be written as:

var opts = Foo.find().map(function(doc) { return doc.getOptions(Session.get('foo')); }); 

getOptions: function(langCode) {
  return { id: this._id, name: this.name[langCode] };
}

The transformation function is applied to the the results of the query, not onto the query cursor itself. See here under transform.

Thanks. I think I prefer as I have it now with less function calls, even if code may be duplicated when this is used several times:

var lang = Session.get('currLang').code;
var opts = Foo.find().map(function(doc) { return { id: doc._id, name: doc.name[lang]}; }); 

Maybe another option would be to augment the collection, as Foo.getOptions(lang)...

In any case, since I got the idea wrong at the beginning, maybe the readme could make it more obvious that what gets new behaviour is each item, and not the collection? Cheers!
