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.

If the user asks to see object blah and that doesn’t exist, then what  
to tell the user is definitely controller material.  
If I were you I’d take a look at rescue\_from.
