Tracking Views in Rails
ActsAsViewable is plugin that allows you to track page and asset views in your Rails application. For example, you can use it to track how many times a page is visited or how many times a particular image is viewed.
Trac: http://trac.intridea.com/trac/public/wiki/ActsAsViewable
Subversion repository: http://svn.intridea.com/svn/public/acts_as_viewable
Installation:
script/plugin install http://svn.intridea.com/svn/public/acts_as_viewable
OR
cd vendor/pluginssvn co http://svn.intridea.com/svn/public/acts_as_viewable
Create the tables where views will be tracked:
class CreateViewings < ActiveRecord::Migration def self.up create_table :viewings do |t| t.column :viewable_type, :string t.column :viewable_id, :integer t.column :views, :integer, :default => 0 t.column :created_at, :datetime, :null => false t.column :updated_at, :datetime end end def self.down drop_table :viewings endend
class SomeAsset < ActiveRecord::Base acts_as_viewableend
Now you can increment views for these objects wherever you need to. For example in the show action of our SomeAssetController:
class SomeAssetController < ApplicationController def show @some_asset = SomeAsset.find(params[:id]) @some_asset.increment_views endend
To get the number of views:
@some_asset.views
Automatically Expiring Sessions in Rails
SessionExpiration is plugin that allows you to expire sessions after X seconds of
inactivity. Useful for when you want to automatically log out users if they’re idle.
Trac: http://trac.intridea.com/trac/public
Subversion repository: http://svn.intridea.com/svn/public/session_expiration/
Installation:
script/plugin install http://svn.intridea.com/svn/public/session_expiration
OR
cd vendor/pluginssvn co http://svn.intridea.com/svn/public/session_expiration
Specify when to expire session in your ApplicationController to do it site wide or you can do it for specific controllers:
class ApplicationController expire_session_in 5.minutesend
If you want to run a method when the session expires use this:
class ApplicationController expire_session_in 5.minutes, :after_expiration => :some_method def some_method flash[:notice] = "You have been logged out due to inactivity" endend
WhatMyFriendsLike.com
In addition to MySpace Maps I also created WhatMyFriendsLike.com
It lets you create a ranked list of all the music, movies and books your MySpace friends like.
This one was also written entirely in Ruby on Rails sharing most of the code with MySpace Maps.
