How to dynamically give the collection filed name in Meteor?

I have these codes now:

OneCollection.find({}, {fields: {'oneFiled.child1': 1}});
OneCollection.find({}, {fields: {'oneFiled.child2': 1}});

But I want to give a dynamically child filed name.

let childfield = "child1";
OneCollection.find({}, {fields: {'oneFiled.childfield': 1}});  // How to write this one?

How can I dynamically give the filed name? Thanks

Solution

  • Like this ?

    let childField = 'child1';
let listFields = {};
listFields['oneField.'+childField]=1;
OneCollection.find({}, {fields: listFields });
