使用ActiveModel的Serializer对Rails API进行Swagger UI

我想知道是否有人在使用Swagger UI为Swagger生成的API生成API文档之前完成此操作 . 这是我的一个简单例子：

class Api::V1::UsersController < Api::V1::BaseController
  swagger_controller :users, 'Users'

  swagger_api :show do
    summary 'Returns a user'
    param :path, :id, :integer, :optional, "User Id"
    notes '/api/v1/users/:id'
    response :ok, "Success", :Users
    response :unauthorized
    response :not_acceptable
    response :not_found
  end

  def show
    user = User.find(params[:id])

    render(json: Api::V1::UserSerializer.new(user).to_json)
  end
end

我用 rake swagger:docs 生成了swagger文档，并且在我看到 Users#show 的文档时可以达到 http://localhost:3000/api-docs.json ，但是当我单击"Try it out!"时，我得到 api/v1/users/show 的模板错误

api-docs.json ：

{
  "apiVersion": "1.0",
  "swaggerVersion": "1.2",
  "basePath": "http://localhost:3000",
  "apis": [
    {
      "path": "/api/v1/users.{format}",
      "description": "Users"
    }
  ],
  "authorizations": null
}

users.json ：

{
  "apiVersion": "1.0",
  "swaggerVersion": "1.2",
  "basePath": "http://localhost:3000",
  "resourcePath": "users",
  "apis": [
    {
      "path": "/api/v1/users/{id}.json",
      "operations": [
        {
          "summary": "Returns a user",
          "parameters": [
            {
              "paramType": "path",
              "name": "id",
              "type": "integer",
              "description": "User Id",
              "required": false
            }
          ],
          "notes": "/api/v1/users/:id",
          "responseMessages": [
            {
              "code": 200,
              "responseModel": "Users",
              "message": "Success"
            },
            {
              "code": 401,
              "responseModel": null,
              "message": "Unauthorized"
            },
            {
              "code": 404,
              "responseModel": null,
              "message": "Not Found"
            },
            {
              "code": 406,
              "responseModel": null,
              "message": "Not Acceptable"
            }
          ],
          "nickname": "Api::V1::Users#show",
          "method": "get"
        }
      ]
    }
  ],
  "authorizations": null
}

如何为我的show方法呈现正确的响应，以便它查找序列化的json而不是视图文件？
