ExtJS5:删除代理中的根属性 [英] ExtJS5: Get rid of root property in proxy
问题描述
我正在尝试将REST API连接到我的ExtJS应用程序。
I'm trying to connect a REST API to my ExtJS application.
对于 GET / user
请求我回复如下:
{items: [{id: 1, ...}, {id: 2, ....}], total: 2}
所以我创建了一个模型: / p>
So I created a model for that:
Ext.define('model.User', {
extend: 'Ext.data.Model',
fields: [
{ name: 'id', type: 'int' },
{ name: 'name' },
],
proxy: {
reader: {
type: 'json',
totalProperty: 'total',
rootProperty: 'items'
},
type: 'rest',
url: '/Api/User',
}
});
网格加载数据,看起来完美无缺。现在我想要请求一个记录,我的api用作 {id:1,...}
。
但是当我做 model.User.load(1)
成功处理程序从不被触发,因为响应不包含 items
属性。如果我把我的记录放在该属性中,它将会工作,但对其他API用户来说也是丑陋的。
The grids load data and all look perfect. Now I want to be able to request a single record which my api serves as {id: 1, ...}
.
But when I do model.User.load(1)
the success handler is never triggered because the response doesn't contain items
property. If I put my record in that property, it will work but also will look ugly for other API users.
如何在没有根属性的情况下使其工作?我找不到代理/阅读器上的代理/阅读器的任何事件来动态地改变它。
How can I make it work without the root property? I can't find any events for proxy/reader on a model to change it dynamically.
推荐答案
rootProperty
也可以是一个函数,所以你可以这样做:
The rootProperty
can also be a function, so you could do something like:
rootProperty: function(raw) {
return raw.items ? raw.items : raw;
}
