Ruby on rails 为错误重写respond_的JSON响应

我想用自定义

respond\u的错误响应。它呈现错误的方式如下所示：

# /app/controllers/articles_controller.rb
def create
  article = Article.new(params[:article])
  article.save
  respond_with(article)
end

Response:

{
  errors: {
    title: ["can't be blank", "must be longer than 10 characters"],
    body: ["can't be blank"]
  }
}

class ApplicationResponder < ActionController::Responder
  include Responders::FlashResponder
  include Responders::HttpCacheResponder

  # Redirects resources to the collection path (index action) instead
  # of the resource path (show action) for POST/PUT/DELETE requests.
  include Responders::CollectionResponder

  def json_resource_errors
    { errors: resource.errors }
  end
end

我想让它以不同的方式回应。有没有办法覆盖这种格式

我已经成功地做到了这一点，通过猴子修补ActionController:：Responder类并重新定义
json\u resource\u错误
，但这似乎是一种不好的方法
 最简单的方法是不要使用
respond\u with
，而是使用
respond\u to
（）

好的，正确的方法是自定义json_资源_错误，例如您的应用程序_responder.rb

例如：

# /app/controllers/articles_controller.rb
def create
  article = Article.new(params[:article])
  article.save
  respond_with(article)
end

Response:

{
  errors: {
    title: ["can't be blank", "must be longer than 10 characters"],
    body: ["can't be blank"]
  }
}

class ApplicationResponder < ActionController::Responder
  include Responders::FlashResponder
  include Responders::HttpCacheResponder

  # Redirects resources to the collection path (index action) instead
  # of the resource path (show action) for POST/PUT/DELETE requests.
  include Responders::CollectionResponder

  def json_resource_errors
    { errors: resource.errors }
  end
end

class ApplicationResponder
