You need to use AJAX if you want to update your data without reloading the edit.html.erb file. Below, I'm gonna show it how to this for one field, rest you can assume yourself.
<input id="product_price" name="product[price]" type="text" value="<%= product.price %>" />
In your js.erb file, you can write:
$("#product_price").focusout(function() {
var productPrice = $(this).val();
$.ajax({
url: "/products/<%= product.id %>/edit",
type: "POST",
data: { product_price: productPrice}, // same way, other attributes
success: function() {
console.log("The result successfully came back from ther server.");
// Now, here you can show a notice to the user that he has successfully update the record without reloading the page.
}
});
});
