Handling ActiveRecord::RecordNotFound in Ruby on Rails

Question

In my edit action, I have

@item = current_user.shop.items.find(params[:id])

So that the user can only edit items that belong to their shop. If they try to edit an item that does not belong to their shop, then they get an ActiveRecord::RecordNotFound error.

What is the best way of handling this error in situations like this? should i raise an exception? should i redirect somewhere and set the flash (if so, how do i do that), should i just leave it as is? Any advice is appreciated.

Thanks

Add something like the following to your controller:

rescue_from ActiveRecord::RecordNotFound do
  flash[:notice] = 'The object you tried to access does not exist'
  render :not_found   # or e.g. redirect_to :action => :index
end
