javascript - AutoForm Select2 Meteor で自分のユーザー ID にアクセスするには?

Question

私は Select2 AutoForm を使用しており、次のスキーマがあります。

Schema = {};
Schema.users = new SimpleSchema({
    users: {
        type: [String],
        autoform: {
            type: "select2",
            options: function () {
                return Users.find().map(function (user) {
                    return {label: user.username, value: user._id};
                });
            }
        }
    }
});

これでうまくいきましたが、問題は、現在ログインしているユーザー名もオプションとして表示されることです。この特定のオプションを削除したいので、次のことを試しました。

Schema = {};
Schema.users = new SimpleSchema({
    users: {
        type: [String],
        autoform: {
            type: "select2",
            options: function () {
                var userId = this.userId;
                return Users.find().map(function (user) {
                    if(user._id != userId) return {label: user.username, value: user._id};
                });
            }
        }
    }
});

ただし、this.userId利用できません。この変数にアクセスするにはどうすればよいですか?

編集: クライアント側でオプションを設定しようとしましたが、うまくいきませんでした:

Template.users.helpers({
    userFormSchema: function () {
        return Schema.users;
    },
    usersOptions: function () {
        return Users.find().map(function (user) {
            if (Meteor.userId() != user._id) return {label: user.username, value: user._id};
        });
    }
});

<template name="users">
    <div class="page-content">
    {{#autoForm schema=userFormSchema id="insertUserForm" type="method" meteormethod="userInsert"}}
        {{> afFieldInput name="users" type="select2" multiple=true options=usersOptions}}
        <button type="submit" class="btn btn-primary">Submit</button>
    {{/autoForm}}
    </div>
</template>

次の例外があります。

問題は、内のオブジェクトを返していなかったことcursor.map()です。それで戻ってき{}ましたが、空のオプションが表示されたため、これは私の望ましい結果ではありませんでした。

ただし、これは私がこの問題を修正した方法です：

Schema = {};
Schema.users = new SimpleSchema({
    users: {
        type: [String],
        autoform: {
            type: "select2",
            options: function () {
                return Users.find({_id: {$ne: Meteor.userId()}}).map(function (user) {
                    return {label: user.username, value: user._id};
                });
            }
        }
    }
});

javascript - AutoForm Select2 Meteor で自分のユーザー ID にアクセスするには?
