在Rails 4中格式化我的JSON输出


Pretty format my JSON output in Rails 4

我正在控制器中使用pretty_generate，但我得到以下错误

'只允许生成JSON对象或数组'

@celebrities = Celebrity.includes(:category)    
respond_to do |format|
  format.json { render json: JSON.pretty_generate(@celebrities.to_json(:include =>{:category => {:only => [:category]} })) }
end

我不知道为什么会出现这个错误

相关讨论

as the error蓝晶石，only generation of JSON objects or arrays allowed。我想你应该试试这个。P＞＜／
