ListingFu is a compact DSL for defining and searching in lists of content in your Rails app, it uses ferret as backend to work its fast magic.
We define our different filters we want to use in our app inside the model:
class Person < ActiveRecord::Base has_many :memberships has_many :groups, :through => :memberships has_one :account listing_filter :name => :name, :age => :age, :account_name => lambda { account.name }, :groups => lambda { groups.join(' ') } end
In our view we can now use our defined filters to filter the listing to find the content we want:
<% filters(@people) do |filters| %> <%= filters.text_filter :name %> <%= filters.options_filter :age, [12, 13, 14] %> <% end %>
This is the actual listing code that renders a table with clickable headers to do the sorting:
<% listing(@people) do |listing| %>
<%= listing.column :name %>
<% listing.column :age do |person| %>
<%= "My age is #{person.age}" %>
<% end %>
<% listing.actions do |person| %>
<td><%= link_to 'Show', person %></td>
<td><%= link_to 'Edit', edit_person_path(person) %></td>
<td><%= link_to 'Destroy', person, :confirm => 'Are you sure?', :method => :delete %></td>
<% end %>
<% end %>
Then in our controller we just use the listing method with the parameters from the view
@people = Person.listing params, :per_page => 50
