Rails - Dec 2005 - yaml Error When Trying to Generate Scaffold

Hello there,

I am a Ruby on Rails newbie, and have been reading the book, "Agile  
Web Development with Rails", by Dave Thomas.

Seem to be stuck on page 57, when trying to invoke "ruby script/ 
generate scaffold Product Admin"...

My depot/config/database.yml file''s contents are:

development:
   adapter: mysql
   database: depot_development
   socket: /tmp/mysql.sock
   username: untz
   password: paintball

# Warning: The database defined as ''test'' will be erased and
# re-generated from your development database when you run
''rake''.
# Do not set this db to the same as development or production.
test:
   adapter: mysql
   database: depot_test
   socket: /tmp/mysql.sock
   username: untz
   password:     paintball

production:
   adapter: mysql
   database: depot_production
   socket: /tmp/mysql.sock
   username: untz
   password: paintball

When I created these tables using MySQL 5, I issued the following in  
the MySQL Command Line Monitor:

grant all on depot_development.* to
''untz''@''localhost'' identified by
''paintball'';
grant all on depot_test.* to
''untz''@''localhost'' identified by
''paintball'';
grant all on depot_production.* to
''untz''@''localhost'' identified by
''paintball'';

When I tried to generate a scaffold, this is the error I received:

Raven:/Developer/DevResources/Ruby/RailsApps/depot untz$ ruby script/ 
generate scaffold Product Admin
/usr/local/lib/ruby/1.8/yaml.rb:133:in `load'': syntax error on line

lib/active_support/dependencies.rb:214:in `require''
         from script/generate:3

I am using ruby 1.8.3 (2005-09-21) [powerpc-darwin8.2.0] on OS X  
Tiger and Rails 0.14.3...

Is the Ruby 1.8.3''s yaml corrupt?

Please help! I am at this point, stuck... I really want to learn  
"Ruby on Rails", so any
tips, suggestions, and hints would be greatly appreciated.

Is there a setting in Rails where I change a configuration to point  
to the prospective Ruby 1.8.3 on my local machine?

Do I need to re-install Ruby 1.8.2?

Many, many thanks!

The error that you''re seeing often indicates a whitespace problem in
the
YAML.  Tabs are illegal in YAML so make sure that all of the whitespace
in your file truly are spaces and not tabs.

If that doesn''t work, there may be something else going on, but
that''s a
good place to start.

On a second glance, it also might be those extra spaces between
''password:'' and ''paintball''.  Make sure
that''s not a tab and that
there''s only one space.

Ok, that''s a good observation... On gvim, it doesn''t show the
tab and
using pico, it does show the spaces....

When I fixed it and re ran the attempt to generate a scaffold, this  
is the new error I got:

ruby script/generate scaffold Product Admin
       exists  app/controllers/
       exists  app/helpers/
       exists  app/views/admin
       exists  test/functional/
   dependency  model
       exists    app/models/
       exists    test/unit/
       exists    test/fixtures/
    identical    app/models/product.rb
    identical    test/unit/product_test.rb
    identical    test/fixtures/products.yml
       create  app/views/admin/_form.rhtml
Permission denied - ./app/views/admin/_form.rhtml

Any suggestions?

Many, many thanks!
