Question

   end

Answer 1

Catch:

Your console log says:

Processing by Oweb::MainController#setmagasinstatus as HTML

In your controller action, you don't have supported HTML response. That's why you are facing error of UnknownFormat.

Solution:

Add format: "js" in your ajax call. For example:

$.ajax url: "/oweb/main/setmagasinstatus", data: 'id=' + id, format: 'js'
