Javascript 我不断得到：“未捕获的TypeError:无法读取未定义的属性'insert'”

我将cfs文件系统与autoform一起使用，我已使用collectionFS和meteor cfs autoform中的文档进行了设置，但当我尝试提交表格为我的学校收藏创建记录时，出现了上述错误。我不确定我遗漏了什么，也不确定错误是在哪里产生的

common.js：

// File methods
 Images = new FS.Collection("images", {
  stores: [new FS.Store.FileSystem("images", {path: "~/img/uploads"})]
 });

 Images.allow({
  download: function () {
  return true;
},
fetch: null
});

school_collection.js：

Schools = new Mongo.Collection("Schools");


//Defining the schema
Schools.attachSchema(schoolSchema = new SimpleSchema({
name: {
type:String,
label: "Name",
max:200
},
primary_color: {
 type:String,
 label: "Color",
 optional: true
},
sub_domain: {
 type:String,
 label: "Sub Domain",
 max:50
},
user_id:{
 type: String,
 autoform: {
  type: "hidden",
  label: false
},
autoValue: function(){
  if (this.isInsert) {
        return Meteor.userId();
    } else if (this.isUpsert) {
        return {$setOnInsert: Meteor.userId()};
    } else {
        this.unset();
    }
  },
denyUpdate:true
},
image: {
 type: String,
 label: "Logo",
 autoform: {
   afFieldInput: {
     type: "cfs-file",
     collection: "files"
   }
 }
} 
}));

school_create.html

{{#autoForm collection="Schools" id="school_create" type="insert"}}

  Add a School




      {{> afQuickField name='name'}}




      {{> afQuickField name='sub_domain'}}

你能在Meteopad上给我一个简单的演示吗？
