Answer 1

You should do this:

1. Make sure that you have <%= csrf_meta_tag %> in your layout

2. Add beforeSend to all the ajax request to set the header like below:

---

$.ajax({ url: 'YOUR URL HERE',
  type: 'POST',
  beforeSend: function(xhr) {xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'))},
  data: 'someData=' + someData,
  success: function(response) {
    $('#someDiv').html(response);
  }
});

To send token in all requests you can use:

$.ajaxSetup({
  headers: {
    'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content')
  }
});
