------------>There is a database (specs) with a table (tareas)

C:\proys>cd specs4

C:\proys\specs4>ruby script\generate scaffold Tareas
exists app/controllers/
exists app/helpers/
create app/views/tareas

oooooooops there are some problem
OK. Continue for a longer way.

C:\proys\specs4>ruby script\generate controller Tareas

create app/models/tarea.rb
create test/unit/tarea_test.rb
overwrite test/fixtures/tareas.yml? [Ynaq] y
force test/fixtures/tareas.yml

-----------> Editing tareas controller

C:\proys\specs4>cat app\controllers\tareas_controller.rb

Hi Jose,

I have problems starting with rails.
I hope this description is enough.

are you using 2 versions of Ruby? It looks like it because you use `cat`
which indicates that you use cygwin. It might be that when you just call
`ruby` that the cygwin ruby is called. I had a lot of problems with
"stack level too deep" months ago with rails-0.8. Try doing

"c:\ruby\bin\ruby.exe" script\generate scaffold Tareas
