How to make a selection for deletion in mongoDB from Meteor.JS?

Question

JavaScript

Greetings! I'm going through a tutorial on the Meteorjs website on how to create a Todo application, and in the process there was a problem, or rather, with a request to delete all records where checked is true (the code is attached).

Template.users.events({
        "click .toggle-checked": function() {
            Users.update(this._id, {$set: {checked: ! this.checked}});
        },
        "click .delete": function() {
            Users.remove(this._id);
        },
        "click .alldel": function() {
            // так не работает, по идее должно вот так быть Users.remove(checked: true); но и так не работает
            Users.remove({}, {$where: {checked: true}});
        }
    });

Answer 1

$where doesn't work that way. It takes either a string or a function: $where: 'return this.checked'either $where: function () {return this.checked}. $where has low performance, so it is recommended to use it only if there is no other way .
Not to mention that the condition should still be the first argument, not the second.

Users.remove(checked: true)

If you wrote it directly, then this is a syntax error, it should be:Users.remove({checked: true})
