Ember存储查询模板没有模型数据 [英] Ember store query template no model data

问题描述

如何Ember模型存储查询不会更新模板模型数据， find 是否有效？

How come Ember model store query doesn't update template model data and find does?

// This doesn't update the template, when loading website no information is displayed but the data is loaded
model: function() {
    var parentModel = this.modelFor("server.view");
    return this.store.query("server", { server_address: parentModel.server_address });
}

// This works without any problems
model: function() {
    var parentModel = this.modelFor("server.view");
    return this.store.find("server", 1);
}

推荐答案

所以我想出了为什么我模板没有呈现模型数据。使用 store.query ，它期望多个结果，而 store.find 只需要一个结果，这就是为什么它的工作。我正在使用 server_address 作为查找中的id，但它开始让我受益。

So I figured out why my template was not rendering model data. Using store.query it expects multiple results while store.find expects only one result and that's why it worked. I was using server_address as an id in find but it started to get in my way.

这是我得到的 store.query 可以处理单个结果。

Here's how I got store.query to work on a single result.

return this.store.query("server", { param: value }).then(function(res) {
    return res.get("firstObject");
});
