Rails：使用Jquery发送Ajax对象并将数据类型保持在Rails上

Question

I'm using Jquery for creating object and sending to server:

    data = {};
    data.number = 5;
    $.ajax({
        url: 'some_link',
        type: 'POST',
        dataType: 'json',
        data: data,
        success: function() {
            alert('data sent');
        },
        error: function() {
            alert('fail');
        }
    });

And on rails, I test submitted param by:

params[:number] => "5"

How can I force rails to understand 5 instead of "5". Because I send a large bunch of data, I cannot manually do conversion.

Thanks

If you need to save to a database, then your model should have the attribute type set as integer . When you save it, it will automatically coerce the string '5' into the integer 5
