Rails how to create sortable rows?
How do I create a sortable rows with Rails and Jquery.
I have added a column named position to my table that I want to have sortable rows.
I have created this action in my controller:
def sort
params[:faqs].each_with_index do |id, index|
Faq.update_all(['position=?', index+1], ['id=?', id])
end
render :nothing =&g开发者_如何转开发t; true
end
And created a route for the action. But how do I create a table with sortable rows? Instead of a sortable list: http://railscasts.com/episodes/147-sortable-lists
You need to add a new integer datatype cloumn in table. Take a look at following jquery plugin for sorting elements.
http://jqueryui.it/demos/sortable
Below is an example of sorting elements.
<!DOCTYPE html>

<head>
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/>

</head>
<body style="font-size:62.5%;">
<ul id="sortable">
<% unless @images.blank? %>
<% @images.each do |image| %>
<li id="<%= image.id %>">Item 1</li>
<% end %>
<% end %>
</ul>
<script type"text/javascript">
$(document).ready(function() {
$('.sortable').sortable({
update: function(event, ui) {
var question_list = $(this).sortable('toArray').toString();
alert(question_list);
//this will give you the new order list from here you can fire ajax call for updating the order
}
});
});
</script>
</body>
</html>
