ruby-on-rails - rails : change default JSON structure

Question

我是 Rails 的新手，我使用的是 4.2.0 版本。

假设我们在 url localhost:3000/users 处有以下 JSON

[{id: 1, "firstName": "John","lastName": "Smith"},
{id: 2, "firstName": "John","lastName": "Red"}]

但这不是我想要的，我希望是这样的:

{ users :[
{id: 1, "firstName": "John","lastName": "Smith"},
{id: 2, "firstName": "John","lastName": "Red"}
]}

我该怎么办？谢谢大家。

Answer 1

在用户索引 Controller 中试试这个

render json: {users: @users}

在哪里

@users = [{id: 1, "firstName": "John","lastName": "Smith"},
          {id: 2, "firstName": "John","lastName": "Red"}]
