我的模型在下面
Ext.define('DEV.model.employeetaskdetModel', {
extend: 'Ext.data.Model',
fields : [
{ name: 'id'},
{ name: 'taskname', mapping:'task.taskname'},
{ name: 'firstname', mapping: 'employee.firstname'},
{ name: 'employee',type: 'auto'},
{ name: 'percentdone'}
]
});
和我的网格面板列在下面
and my grid panel columns are below
columns: [ {
xtype: 'gridcolumn',
dataIndex: 'percentdone',
text: 'Percent Done'
}, {
xtype: 'gridcolumn',
dataIndex: 'firstname',
text: 'First Name'
}]
我无法在我的gridPanel中显示名字.但是，当我用下面的代码更改firstname列时，它可以正确显示firstname网格面板.
I am not able to show the firstname in my gridPanel. But when I change the firstname column with below code it shows me the firstname gridpanel correctly.
{
xtype: 'gridcolumn',
dataIndex: 'employee',
text: 'User Name',
renderer: function (employee) {
var result = [];
employee = employee || [];
var value = employee.firstname;
if (value) {
result.push(value);
}
return result;
console.log(employee.firstname);
}
},
请向我建议为什么我的网格面板没有直接显示用户的名字.我的代码有什么问题.以及为什么在添加渲染器功能时显示数据.
please suggest me why my gridpanel didn't show the firstname of user directly. What's the problem with my code. And why its showing the data when I add the renderer function.
推荐答案
我遇到了类似的问题并将其解决.
I encountered a similar problem and solve it.
映射属性对于映射嵌套的json数据不是必需的.
Mapping property is not required for mapping nested json data.
型号:
Ext.define("Model", {
extend: "Ext.data.Model",
fields: [
{name: "id", type: "int"},
{name: "name.name"},
{name: "phone", mapping: "name.phone"},
{name: "descr", type: "string", mapping:'description'}
]
});
存储我们将从jsfiddle测试echo ajax服务接收的数据:
Store with data that we will recieve from jsfiddle test echo ajax service:
var Store = Ext.create("Ext.data.Store", {
model: "Model",
autoLoad: true,
proxy: {
type: 'ajax',
url: '/echo/json/',
//
actionMethods: {read: 'POST'}, // echo ajax service required
extraParams: {
json: Ext.JSON.encode({
root: [
{id: 1, name: {name:"John", phone: "123"}, description:"Fapfapfap"},
{id: 2, name: {name:"Danny", phone: "234"}, description:"Boobooboo"},
{id: 3, name: {name:"Tom", phone: "345"}, description:"Tralala"},
{id: 4, name: {name:"Jane", phone: "456"}, description:"Ololo"},
]
})
},
reader: {
type: 'json',
root: 'root'
}
},
});
网格:
Ext.create("Ext.grid.Panel", {
store: Store,
columns: [
{dataIndex: "id", header:"ID"},
{dataIndex: "name.name", header:"Name", flex: 1, editor: "textfield"},
{dataIndex: "phone", header:"Phone", flex: 1, editor: "textfield"},
{dataIndex: "descr", header: "Description", flex: 2, editor: "htmleditor"}
],
renderTo: Ext.getBody(),
});
如果没有其他问题，这应该可以工作.
This should work, if other problems is absent.
