这个网站展示了将信息从Rails传递到angle的4种方法

Option number 3 states that if you are going to use interpolation like that, you may need to call .html_safe like shown in this example.

选项3指出，如果要像这样使用插值，可能需要调用。html_safe，如本例所示。

itemsApp.service('itemsAppInitializer', function(){
  return <%= @item.to_json.html_safe %>;
});

In my opinion, there could be one other way that you could tackle this issue if you wanted to. I would create a route in rails that returns env variables to you in the response.

在我看来，如果你想解决这个问题，还有另外一种方法。我将在rails中创建一条路径，在响应中向您返回env变量。

Then whenever the service needs to provide env variables for the first time, you can use $http.get() with the cache: true option added in your service call to fetch that data from the route/controller, and only need to fetch it once.

然后，每当服务需要首次提供env变量时，您可以使用$http.get()和缓存:true选项，该选项在服务调用中添加，以从路由/控制器获取数据，并且只需要获取一次。
