Here is my solution:
def client_name_column(record)
if record.respond_to?('deployment_id') &&
!record.deployment_id.nil?
deployment = Deployment.find(record.deployment_id)
if deployment.respond_to?('client_id') && !
deployment.client_id.nil?
client = Client.find(deployment.client_id)
link_to(h(client.name), {:action => :show,
:parent_controller =>
'inactive_applications', :controller => 'clients', :id => client.id},
{ :class => "action", :position => "replace"})
end
end
end
The only problem that remains is that I have to hard code the
"parent_controller" value in the helper. At the moment I only need to
call it from one controller, but if I want to use the same helper from
another controller, I'm in trouble.
Anyone know enough about ruby reflection to tell me if there is any
way to get at the name of the controller calling this method?
