Error in executing the scaffold

Good night.

I am starting in linux and development in Ruby.
I have not much expertise in this area.
I'm using ruby + rails + postgres + RadRails.

I generated a CRUD for testing as follows below:
scaffold Teste nome:string login:string senha:string

When I run this application showing the following error:

NameError in Testes#index

Showing app/views/testes/index.html.erb where line #24 raised:

undefined local variable or method `new_teste_path' for

Extracted source (around line #24):

22: <br />
24: <%= link_to 'New teste', new_teste_path %>

RAILS_ROOT: /home/adriano/Aptana Studio Workspace/teste
Application Trace | Framework Trace | Full Trace

app/controllers/testes_controller.rb:7:in `index'
-e:2:in `load'

Please help me solve this problem.

Thanks ...

Did you run 'rake db:migrate' after you created the new scaffold?
Also, if you did not do it yet, you will also have to run 'rake
db:create' to create the db before you run the migration.

Thank you...

The error was happening only when I created the scaffold/migrate for
So I created the first scaffold/migrate through the terminal and the
other by RadRails and it worked.
