In fact, I see two ways of doing this: either expose Documents array as a global variable, or attach a new field to the collection intself. Both are illustrated below:

After this, I seem to be able to do

univ = new CollectionHelpers["universities"]({name :"abc"})

univ = new UniversitiesCollection.collectionHelper({name:"abc"})

Is there any drawback from this approach? Or is there any better way to accomplish this?

Hey @petr-kalinin just do this: univ = UniversitiesCollection._transform({ name: "abc" });

from meteor-collection-helpers.

petr-kalinin commented on May 22, 2024

Oh, yes, indeed, did not think about this!

(Though I do not completely like this solution, as it seems to be some internal Meteor field that can be renamed or dropped in future, but I think it's ok for my tests, so thank you!)
