如何在rails json响应中合并图像url？

Question

我想发送@survey image_url 及其属性。我如何发送它

@survey_detail = @survey.as_json(:include => { :questions => { :include => { :options => {:only => :title } } } })
render json: {:success=>true, :message=>"Detail of survey",:survey=>@survey_detail}, :status=>200

连同@survey 其他属性，我想发送@survey.image.url。我想将它与其他调查属性合并。

我该怎么做？

你可以发送多少你想要的属性。只需像这样添加它们：

render :json => {:success => true, :message=>'Your message', locals => {:survey =>@survey_detail, ....here you an add what attributes you want to send... }
