A newbie doomed in the first introduction to ruby

Hello,

I have bought the Dave T. Agile Developtment with Rails. (I have
previously bought and read his Programming with Ruby book)

On my winxp sp2 system ruby 1.8.15 (one click installer), rails
1.0framework (with ruby gems) and mysql
5.0 are installed.

While following the example stated in the Chapter Building an
Application I
had following problem.

After creating databases for test, production, development, and creating
a
Product table for development database,
I modified the config/database.yml file and I issued the command “ruby
script/generate scaffold Product Admin” depot application

I have received “No connection could be made beacuse the target machine
actively refused it. - connect(2)” while generate script processing
product.yml file.

I tought that it was a firewall problem and disabled the personal
firewall.
After issuing the same command I still received the same error.

When I tried to acces localhost:3000/admin site, I receive a page on
which
“recognition failed for /admin” is written.

I do not think that I misconfigured database.ym file. I put the users
and
their passwords whom all are granted access to the specified databases.

development.log has following line for each attempt I made

Any help will be greatly appreciated.

sounds like a mysql issue. can you connect to the dbs as the users you
have
configured in database.yml through other means (ie, besides rails)?

in database.yml, are you using the socket or host configuration to
connect?
i think by default host is commented out, and socket enabled. try
commenting
out the socket line for the dbs, and uncommenting the host and port
lines.

also, the necessary grants are specified on pg 54 of ‘agile’, and this
helps
too:
http://dev.mysql.com/doc/refman/5.0/en/adding-users.html

just some thoughts. good luck.

I’ve posted this before, but it might help. Of course this kind of
setup
will need to be adjusted if the databases do not all have the same user
name
and password.

authentication: &authentication
adapter: mysql
host: host_name_here
username: user_name_here
password: mysql_password_here

development:
database: db_development
<<: *authentication

test:
database: db_test
<<: *authentication

production:
database: db_production
<<: *authentication
