如何将嵌套模型与主干表单列表一起使用？我想使用自定义模板制作一个嵌套模型，但这给出了一个错误："未定义的渲染"

我想使用自定义模板通过骨干表单制作视图。模板是

<div class="container-fluid add-apikey" data-class="add-apikey">
<div class="page-head">
    <h2>API Key</h2>
</div>
<div class="cl-mcont">
    <div class="row">
        <div class="col-sm-12">
            <!-- New Zone -->
            <div class="block-flat">
                <form class="form-horizontal" role="form">
                    <div class="header">
                        <h3>Create New API Key</h3>
                    </div>
                    <div class="content">
                        <div class="formAlerts"></div>
                        <div class="formconfirm"></div>
                        <div class="required" data-fields="apiName">
                        </div>
                        <div class="required" data-fields="notes">
                        </div>
                        <div class="required" data-fields="weapons">
                        </div>
                        <div class="form-group editmode">
                            <div class="col-sm-offset-3 col-sm-9">
                                <button class="btn btn-primary readOnlySave" type="button">Generate Key</button>
                                <button class="btn btn-default readOnlyCancel">Cancel</button>
                            </div>
                        </div>
                    </div>
                </form>
            </div>
        </div>
        <!-- end new zone -->
    </div>
</div>

而 js 是

//Add api keys
var //util
    util = require('./../../../util/util.js'),
    apiKeyAddTpl = require('./../templates/apikeyadd.hbs'),
    backboneFormList = require('backboneFormsList'),
    backboneFormsModal = require('backboneFormsModal');
module.exports = Backbone.Form.extend({
    template: apiKeyAddTpl,
    schema: {
        apiName: {
            type: 'Text',
            fieldClass: "field-apiName form-group",
            editorClass: "form-control editmode"
        },
        notes: {
            type: 'List',
            fieldClass: "field-notes form-group",
            editorClass: "form-control editmode"
        },
        weapons: {
            type: 'List',
            itemType: 'Object',
            fieldClass: "field-weapon form-group",
            editorClass: "form-control editmode",
            subSchema: {
                id: 'Number',
                name: {
                    type: 'Text'
                }
            }
        }
    }
});

但是当我想在武器下添加一个字段时，这给了我一个错误。错误是：无法读取未定义的属性"渲染"。

您需要扩展视图：Backbone.View.extend 。此视图具有el属性。您必须将此属性与form 相关联。视图具有可以重写的方法render。文档：骨干视图
