Exception handling

Rails
1

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

Hi
Thanks. But how can I handle in code?

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
