Question

我创建了跨平台表单来提交数据。它以json格式发送数据，但rails控制器将其作为html响应。所以我总是得到错误。

    Object {readyState: 0, responseJSON: undefined, status: 0, statusText: "error"}

    test.html?batch[status]=0:88

    Navigated to file:///home/shital/workspace/shitalluitel.github.io/test.html?batch%5Bstatus%5D=0

这是我的表单提交后的rails日志...

Answer 1

您可以使用

render json: {your_response: "value"}, status: 200

或者如果你什么都不想，那么

 render :nothing => true

您可以根据需要更改状态。

Answer 2

您可以在控制器中尝试此操作，响应将根据您的平台自动变化

respond_to do |format|
  format.html { render 'filename.html'}
  format.json { render json: @batches }
end

在跨平台响应期间更改对rails中的json响应的html响应
