In the models you can set up the relation between the Station and the Store models in the relations function if you use Active Record. Obtaining the id of a Store is then possible using one short line of code (something like $storeId = $model->store->id;). So you can easily put this code into your controller and still keep the controller lean (Lean controllers, fat models).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
