This plugin is extracted from several applications where I had similar problems:
tracking various things that users did within the application. For example, I've
used this to be able to log outgoing clicks without hooking up an analytics package,
to count the number of times an ad was displayed, or to keep track of how often
a particular page was visited.
To use the plugin, you must first create the table that it uses:
./script/generate user_event_logger add_event_table
rake db:migrate
After that, you can add information to the table from either your controllers or
your views:
log_user_event "In controller", "", "27"
<%= log_user_event "In view", "", "27" %>
The first argument is the event name, which is required. The second is the
destination URL, which is optional. The third is arbitrary extra data, which is
optional. The extra data is stored in a text column, so you can add as much
as you want here.
Reporting is left as an exercise for the user. The events table has these columns:
create_table :events do |t|
t.column :source_url, :string
t.column :destination_url, :string
t.column :remote_ip, :string
t.column :logged_at, :datetime
t.column :extra_data, :text
t.column :event_type, :string
To do outgoing link tracking, you can set up a controller method similar to this one:
def send_to
@advertiser = Advertiser.find(params[:id])
destination_url =^www/, "http://www")
log_user_event "Clicked through", destination_url, params[:id]
redirect_to destination_url
Extra columns
You can add extra application-specific columns to the events table if you like. To do so, modify
the migration to include the columns after you run the add_event_table rake task and before you
run the migration. Then you can pass a hash of extra options as part of the call to log_user_event:
log_user_event "In controller", "", "27", {:user_id => 13, :product_id => 7}
<%= log_user_event "In view", "", "27", {:user_id => 13, :product_id => 7} %>
Gem installation
If you are running rails 2.1 or above you can choose between a standard plugin install and a gem install. To
install as a gem, add this to your environment.rb file:
config.gem 'ffmike-user_event_logger', :source => ''
and then run:
rake gems:install
