Answer 1

Indeed simplest way. Don't bother with changing the headers.

Make sure you have:

<%= csrf_meta_tag %> in your layouts/application.html.erb

Just do a hidden input field like so:

Or if you want a jQuery ajax post:

$.ajax({     
    type: 'POST',
    url: "<%= someregistration_path %>",
    data: { "firstname": "text_data_1", "last_name": "text_data2", "authenticity_token": "<%= form_authenticity_token %>" },                                                                                  
    error: function( xhr ){ 
      alert("ERROR ON SUBMIT");
    },
    success: function( data ){ 
      //data response can contain what we want here...
      console.log("SUCCESS, data="+data);
    }
});
