如何在AutoForm Select2 Meteor中訪問自己的用戶ID？

我使用自動窗體選擇二，我有以下模式：如何在AutoForm Select2 Meteor中訪問自己的用戶ID？

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}; 
       }); 
      } 
     } 
    } 
});

現在這個工作太棒了，但問題是當前登錄用戶名也被列爲一個選項。我想，所以我嘗試了以下刪除此選項格外：

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}; 
       }); 
      } 
     } 
    } 
});

然而，this.userId不可用。我怎樣才能訪問這個變量？

編輯： 我試圖設置的選項客戶端，但沒有成功：

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>

我得到了以下情況除外：

有了自動窗體您可以選擇2指定模板內或架構中的選項。如果您在模板中指定它們，您將擁有'Meteor.userId（）' – challett

問題是我沒有在內部返回一個對象。 所以我回來了{}但這不是我想要的結果，因爲現在有一個空的選項顯示。

不過，我這是怎麼固定的這個問題：

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}; 
       }); 
      } 
     } 
    } 
});
