Rails - Apr 2010 - exception handling

Hi
  I have controller edit action like

def edit
  begin
    @user = User.find(params[:id])
   rescue ActiveRecord::RecordNotFound
    logger.warn "User with id #{current_user.id} tried to edit user with
id #{params[:id]}"
    render :file => "#{RAILS_ROOT}/public/404.html"
  else
    -------
  end
end

    And suppose if current_user has noa ccess to user with id = 10.Then
when try
http://localhost:3000/edit/10
    This will render the 404.html

     Now my problem is suppose if the user try something like
http://localhost:3000/edi123t/10
    Then what I get is a routing error. I dont know how to handle this.
Please help.

Thanks
Tom

Well you can specify a default page / controller action to perform for
unmatched routes as well...so if the route doesn''t exist it shows a
much
user friendly page instead of the rails error message

Hi,


In application controller

rescue_from
ActiveRecord::RecordNotFound,ActionController::RoutingError,
             ActionController::UnknownController,
ActionController::UnknownAction, ::NoMethodError,
             :with => :handle_exception


# To handle Exceptions
  def handle_exception
    redirect_to no_access_url   # redirect to a page with u need show
  end
