在下面的示例中,我在ActionController中调用一个私有方法：Responder将构造json响应,包括您选择的自定义错误响应;所有你需要做的就是填补空白,真的：

def to_json
  json,status = response_data
  render :json => json,:status => status
end
 
def response_data
  status = options[:status] || 200
  message = options[:notice] || ''
  data = options[:data] || []
 
  if data.blank? && !resource.blank?
    if has_errors?
      # Do whatever you need to your response to make this happen.
      # You'll generally just want to munge resource.errors here into the format you want.
    else
      # Do something here for other types of responses.
    end
  end
 
  hash_for_json = { :data => data,:message => message }
 
  [hash_for_json,status]
end
