I am running MySql 5.0.77 and Ruby 2.2.2 I am able to add records - howeevr when I start the server, I am geting following error message. Please help. I am anot able to see the GUI.
I'm guessing you're new to RoR and haven't learned how to read the error messages. Hope this helps.
ArgumentError in UsersController#index
The error is in users_controller.rb in the index method.
NULL pointer given
A NULL pointer is being passed to to something
in the Rails application named 'testapp'
Application Trace | Framework Trace | Full Trace (eval):3:in `each_hash' (eval):3:in `all_hashes'
ah... it's a null pointer in a hash, which probably means it involves a key rather than a value.
The specific problem can be found in line 3 of users_controller.rb which is inside the index method.
The stack trace past here is, for your purposes, typically noise, not signal.
Without seeing the actual code, it's not possible to nail it down further than that. Post the code if you need more help.
Best regards, Bill
