There is many methods to get the controller name for a record. Usually
controller name is the same as table_name, so you could use
record.class.table_name. You can use record.class.name.tableize too. Or you
can use
controller.class.active_scaffold_controller_for(record.class).controller_name
(only for controllers which use ActiveScaffold)
Anyway, controller for record is the current controller, and is set in params.
def client_name_column(record)
if record.try(:deployment) && record.deployment.try(:client)
client = record.deployment.client
link_to(h(client.name), {:action => :show, :parent_controller =>
params[:controller], :controller => 'clients', :id => client.id}, {:class =>
'action', :position => 'replace'})
end
end
