How should we handle requests for invalid objects which do not exist in
database, ActiveRecord::RecordNotFound error ?
I am writing begin-rescue as follows:
def show
begin
@phone = Phone.find(params[:id])
rescue ActiveRecord::RecordNotFound
flash[:notice] = NONEXIST_OBJECT
redirect_to :controller => :phone, :action => :index
else
respond_to do |format|
format.html
format.xml {render :xml => @agenda.to_xml}
end
end
end
Instead of repeating this for show, edit, and delete in every
controller, I would like to put this into an application_controller. How
do I pass current controller name to the application controller? The
controller and model names are matching, so I would generate a class
name from controller name, then do a begin-find-rescue stuff.
Also, does this belong to controller? My first thought was to handle
this in model, as it is related to ActiveRecord. Any thoughts on this ?
Please help me with putting it into app_con anyway.

Amita.
