TypeError: Cannot read property 'slice' of null

Question

我在我的项目中使用自动表单，当我打开表单时出现这个错误不确定这是否是因为任何版本或依赖性，我的自动表单无法正常工作并且我收到此错误，我有屏幕截图和模式代码，下面的表单代码，

模板

<template name="assesmentNew">
  {{#ionModal customTemplate=true}}
    {{# autoForm collection="Assesments" id="assesments-new-form" type="insert"}}
      <div class="bar bar-header bar-stable">
        <button data-dismiss="modal" type="button" class="button button-clear">Cancel</button>
        <h2 class="title">New Assesment</h2>
        <button type="submit" class="button button-positive button-clear">Save</button>
      </div>
      <div class="content has-header overflow-scroll">
        {{> afQuickField name="name" }}
        {{> afQuickField name="email"}}
        {{> afQuickField name="category"}}
        {{> afQuickField name="location"}}
      </div>
    {{/autoForm}}
  {{/ionModal}}
</template>

Collection

Assesments = new Mongo.Collection('assesments');
Assesments.before.insert(function (userId, doc) {
  doc.createdAt = new Date();
});


Assesments.attachSchema(new SimpleSchema({
  name: {
   type: String,
    label: 'First Name',
    autoform: {
      'label-type': 'floating',
      placeholder: 'First Name'
    }
  },
  email: {
    type: String,
    label: 'Email',
    autoform: {
      'label-type': 'floating',
      placeholder: 'Email'
  }
  },
  category: {
    type: String,
      label: 'Category',
    optional: true,
    autoform: {
      options: [
        {value: 'General', label: 'General'},
        {value: 'Reported', label: 'Reported'},
        {value: 'Follow Up', label: 'Follow Up'}
      ],
      type: 'select-radio'
    }
  },
 assesmentDate: {
    type: Date,
    label: 'Assesment Date',
    optional: true
  },
  location: {
    type: String,
      label: 'Location',
      autoform: {
      'label-type': 'floating',
      placeholder: 'Location'
    },
    max: 200
  },
 createdBy: {
    type: String,
    autoValue: function() {
    return this.userId
  }
}
  }
    ));

if (Meteor.isServer) {
  Assesments.allow({ 
    insert: function (userId, doc) {
      return true;
    },
    update: function (userId, doc, fieldNames, modifier) {
      return true;
    },
    remove: function (userId, doc) {
      return true;
    }
  });
}

Answer 1

这是新版 autoform 的 autoform-ionic 新补丁的问题。

显然有些标签被跳过，有些则没有（参见 here）。为了解决这个问题并在您的输入类型不存在时避免此错误（例如，type = number），自动表单呈现的所有模式字段都必须定义一个标签类型选项：

...
autoform: {
   'label-type': 'placeholder',
   placeholder: 'Linha'
}
