RailsSortable
RailsSortable is a simple Rails gem that allows you to create a listing view with drag & drop sorting. The arranged order will be persisted in the table without any pain.
Setup
Add the following to your Gemfile
then run bundle to install them.
gem 'jquery-rails'
gem 'jquery-ui-rails'
gem 'rails_sortable'
And then add the following to the asset pipeline in the application.js
:
//= require jquery
//= require jquery_ujs
//= require jquery-ui/widgets/sortable
//= require rails_sortable
Usage
RailsSortable requires a specific column on the ActiveRecord Model for its implementation.
For instance, the following migration indicates the case that you are attempting to make Item
model sortable.
class CreateItems < ActiveRecord::Migration[5.1]
def change
create_table :items do |t|
t.string :title
t.integer :sort # for RailsSortable
t.
end
end
end
and Item
model as
class Item < ApplicationRecord
include RailsSortable::Model
set_sortable :sort # Indicate a sort column
# without_updating_timestamps: true, # If you do NOT want timestamps to be updated on sorting
# without_validations: true # If you do NOT want validations to be run on sorting
end
and ItemsController
as
class ItemsController < ApplicationController
def index
@items = Item.order(:sort).all
end
end
and the listing view (typically - index.html.erb) as
...
<table>
<tbody class="sortable"> <!-- sortable target -->
<% @items.each_with_sortable_id do |item, sortable_id| %>
<tr id="<%= sortable_id %>"> <!-- Needs id tag on sorting elements -->
<td><%= item.title %></td>
<td><%= item.sort %></td>
<td><%= link_to 'Show', item %></td>
<td><%= link_to 'Edit', edit_item_path(item) %></td>
<td><%= link_to 'Destroy', item, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</tbody>
</table>
<!-- or just invoke model#sortable_id to get the id for sotable -->
...
<% @items.each do |item| %>
<tr id="<%= item.sortable_id %>">
...
finally, apply sortable with Javascript.
$(function() {
$('.sortable').railsSortable();
});
