Ember CLI应用程序中基于环境的主机 [英] Environment-based host in Ember CLI app

问题描述

我正在尝试在Ember CLI应用程序中将适配器配置为根据环境使用其他主机。在开发人员中，我希望它成为当前的默认主机（让我通过-proxy 选项对其进行自定义，但是在生产环境中，我知道它将是 http：//some.url 。

I'm trying to configure the adapter in my Ember CLI app to use a different host based on the environment. In dev, I want it to be the default current host (letting me customize it via the --proxy option, but in production I know it will be http://some.url.

我尝试将 ENV 导入我的应用程序适配器：

I tried importing my ENV into my application adapter:

// adapters/application.js
import DS from "ember-data";
import ENV from "../../config/environment";

export default DS.ActiveModelAdapter.extend({
  host: ENV.host
});

但是我收到一个错误，该错误是 tmp / tree_merger ../ config /environment.js 不存在。

but I'm getting an error that tmp/tree_merger../config/environment.js doesn't exist.

推荐答案

您已经很接近了，应该只去

You are pretty close. You should only going up one step in the directory tree (when you are in a route, controller, etc you need to go up two).

// adapters/application.js
import DS from "ember-data";
import ENV from "../config/environment";

export default DS.ActiveModelAdapter.extend({
  host: ENV.host
});

文档为此处。

请注意，您可能不应该直接在ENV上定义自己的变量。在 config / environment.js

Note you probably shouldn't be defining your own variables directly on ENV. Use ENV.APP in config/environment.js

var ENV = {
  ...
  APP: {
    // Here you can pass flags/options to your application instance
    // when it is created
    host: 'some_host'
  }
};

并以相同的方式访问它

import ENV from '../config/environment';

export default DS.ActiveModelAdapter.extend({
  host: ENV.APP.host
});
