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  
#ActionView::Base:0xb6f93560

Extracted source (around line #24):

21:  
22:   
  
23:  
24: \<%= link\_to ‘New teste’, new\_teste\_path %\>

RAILS\_ROOT: /home/adriano/Aptana Studio Workspace/teste  
Application Trace | Framework Trace | Full Trace

app/views/testes/index.html.erb:24  
app/controllers/testes\_controller.rb:7:in `index' -e:2:in`load’  
-e:2

Please help me solve this problem.

Thanks …

Best Regards

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  
RadRails.  
So I created the first scaffold/migrate through the terminal and the  
other by RadRails and it worked.
