我正在使用剑道网格 [web],并且我有以下 json 数据来呈现网格
{"rowguid":"7e6dfa67-47a2-40fb-b3fb-9d21e9cba1c3","ProductId":100,"Name":"Car","Color":"#aaaaa","size":4,"Cost": 5.26,"Category":{"CatId":1,"Id":"f27b7d43-9b57-470e-97a3-023323a5a7ac","Name":"Vehicle"},"CategoryName":null},{"rowguid": "9cddd550-479c-4df8-883b-50f39e2b4249","ProductId":101,"Name":"bike","Color":"#aaaab","size":5,"Cost":6.26,"Category" :{"CatId":1,"Id":"82842c66-223d-4774-a4b4-b748429f5984","Name":"2Wheeler"},"CategoryName":null},{"rowguid":"1a47a67f-ddff- 401b-adee-b3bb27660e44","ProductId":102,"名称":"飞机","颜色":"#aaaac","尺寸":6,"成本":7.26,"类别":{"CatId":1,"Id":"f5bd0e35-9ff4 -4a09-8b2b-a1f9c28fb60e","名称":"AirCraft"},"CategoryName":null}]
从这个网格可以看出,这个数据源是一个产品模型,它有一个称为 category 的内部属性,它又是另一个具有要使用的 name 属性的对象。
我使用了以下架构
schema: {
model: {
id: "rowguid",
fields: {
rowguid: { editable: false, nullable: true },
ProductId: { editable: true, nullable: true },
Name: { validation: { required: true} },
Color: { type: "string", validation: { required: true, min: 1} },
size: { type: "number", validation: { min: 1, required: true} },
Cost: { type: "number", validation: { min: 1, required: true }, format: "{0:n2}" }
,CategoryName: {field:"Category.Name", type: "string", validation: { required: true }}
}
}
}
和以下列声明
columns: [
{field:"rowguid",tite:"Unique Id"},
{field:"ProductId",tite:"Id"},
{field:"Name",tite:"Name"},
{field:"Color",tite:"Color", template:colorColumnTemplate},
{field:"size",tite:"size",type:"number", format: "{0:n2}"},
{field:"Cost",tite:"Cost",type:"number", format: "{0:n2}"},
//{field:"CategoryName",title:"Category Name",editor:categoryEditor,template: "#=CategoryName#" },
{field:"Category.Name",title:"Category Name",editor:categoryEditor},
{ command: { text: "Actions" }, title: "Action", width: "140px" },
{command: ["edit"], title: "Actions", width: "172px"}
],
在这里,网格显示正常,编辑、更新一切正常。
问题是当我单击“添加新记录”按钮时,出现以下错误
Uncaught TypeError: Cannot read property 'Name' of undefined
这是因为在形成剑道模型时,它会尝试将值读取为
javascript 对象属性events[idx].call(that, e);
是我在剑道网格中添加新行时触发的触发事件中的方法。
有没有办法让我使用 Category.Name 添加新记录。我认为如果我能够在添加新行过程中将模板与网格行附加或关联,那将是可能的。
让我知道是否可能。
