SortableBy
Add sortable table headers to your views and connect them to ActiveRecord queries in your controller.
Installation
Add this line to your application's Gemfile:
gem 'sortable_by'And then execute:
$ bundle installExample Usage
In your view, the sortable_table_header helper method will generate a <thead> element with header tags.
<%= sortable_table_header :users_path do |t| %>
<%= t.sortable :full_name %>
<%= t.sortable :email %>
<%= t.sortable :birth_date %>
<%= t.header :favorite_color %>
<th>Plain HTML is fine too</th>
<% end %>See table_helper.rb for options.
In your controller, use the sortable_by method to configure sorting attributes.
class MyController < ApplicationController
# Configure the sortable attributes
sortable_by :email, # A basic sort
full_name: [:last_name, :first_name], # This will sort on two columns
birth_date: 'birth_dates.date :dir', # This will sort on a joined table
default: :email # The sort to use when none is passed
direction: :desc # Initial sort direction (defaults to :asc)
def index
# Call #sortable_query to produce an ActiveRecord compatible sorting hash
MyModel.where(...).order(sortable_query)
end
endSee params.rb for options.
Icon Support
Font Awesome and Glyphicons are both supported by default. You can also add your own icon strategy.
module SortableBy::IconStrategy
def self.custom(context, dir)
"test: #{dir}"
end
end<%= sortable_table_header :users_path, icon: :custom do |t| %>
...
<% end %>
