SimpleSchema更新错误

Question

I'm trying to create a favorite button by saving the usersId to the logged in users account. The concept is, if there is a userId (user is a favorite), else user is not a favorite. The problem is I'm getting an error update failed: Error: Favorites must be an array and I'm not sure what this means.

Path: schema.js

Schema.UserProfile = new SimpleSchema({
    "favorites.$.favorite": {
        type: Object
    }
});

Path: studentlist.js

Template.student.events({
'click .favourite':function(event,template) {
      console.log('click');
        var candidateId = this._id;

        Meteor.users.update({_id: Meteor.userId() }, { $set: { "profile.favorites": candidateId }});
    }
});

Answer 1

You have basically two errors.

as of the error, you must have defined Favorites property to be an array. and in the code you're trying to update with $set command.

when you're inserting an item into an array in MongoDB, you've to use $push operator.

and the second problem you'll face after fixing this one would be the improper data type insertion. because you've defined favorite to be an object, but trying to insert a mere id.
