在跨平台响应期间将HTML响应更改为Rails中的json响应

Question

I have created cross platform form to submit data. It sends data in json format, but rails controller response it as html. So that I always get error as.

    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

Here is my rails log after my form submit...

Answer 1

You can use

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

or if you want nothing then

 render :nothing => true

You can change the status base on you needs.

Answer 2

you can try this in the controller response will automatically varies according to your platform

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