• Check the Rails logs, there should a full trace for the 500 error, which will tell you where's the problem – a.barbieri Commented Aug 16, 2017 at 10:11
• @a.barbieri it said Processing by RecipesController#like as JSON Parameters: {"id"=>"1"} Can't verify CSRF token authenticity – PrepareFor Commented Aug 16, 2017 at 11:41
• Do you have <%= csrf_meta_tags %> in your view? – a.barbieri Commented Aug 16, 2017 at 11:42
• @a.barbieri no! can i just insert that code in my view? – PrepareFor Commented Aug 16, 2017 at 11:43
• This might be a good starting point. It should go in the head. – a.barbieri Commented Aug 16, 2017 at 11:44

Looks like you are missing your data attribute in you post ajax request that might be throwing the error.

function like(id){
    $.ajax({
        url:"/like/" + id,
        type:"POST",
        dataType:"json",
        data: my_data, // <--- HERE
        success: function(data){
            if(data.result){
                $("#countlike").html("likes " + data.count);
                // $("#count").removeAttr('onclick');
                // $("#count").attr('disabled', 'disabled');
            }
        }
    });
}

Hope it helps. Cheers!
