Hello.
I'm new to RoR. I run RoR on my Slackware. I follow the depot example
and have a problem when run the script:

root@localhost:~/work/depot# ruby script/generate scaffold Admin Product
/usr/lib/ruby/1.8/yaml.rb:133:in `load': syntax error on line 5, col 2:
`  socket:/var/run/mysql/mysql.sock' (ArgumentError)
        from /usr/lib/ruby/1.8/yaml.rb:133:in `load'
        from
/usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/initializer.rb:424:in
`database_configuration'
        from
/usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/initializer.rb:168:in
`initialize_database'
        from

        from
/usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/initializer.rb:42:in `run'
        from ./script/../config/../config/environment.rb:10
        from
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require'
        from
/usr/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active_support/dependencies.rb:214:in
`require'
        from
/usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/commands/generate.rb:1
        from
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require'
        from
/usr/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active_support/dependencies.rb:214:in
`require'
        from script/generate:3

I have check file socket /var/run/mysql/mysql.sock, it exists. I don't
know how to fix.

Thanks

You have an error in the syntax of your database.yml file. You must
have only spaces and no tabs are allowed in yaml. Go through your
whole databse.yml file again and make sure there are no extra spaces
or tabs at all and you should be ok.

Cheers-

Thanks, Ezra. It's worked.
Actually, i have checked database.yml several times before post the
question but i didn't notice tabs, didn't know that tabs aren't allowed.

Yes! the whole tab thing in the YAML should be better documented.

NO TABS IN YAMLS, ONLY SPACES.

I just added this gotcha to
http://wiki.rubyonrails.org/rails/pages/Gotcha

Hopefully it will not strike someone again (wishful thinking)!

Maybe the next best thing to do is to run a script before starting the
server to check for dumb things like that...

Thanks!
Dominique

Have you *seen* the yaml.org faq?  :-)

I believe the point is that 99.9999% of people using database.yml
will not have.

It happens often enough that perhaps the first line of the generated
database.yml file for a new project should say

   # IF YOU SEE STRANGE PROBLEMS WHEN STARTING YOUR APP, CHECK FOR
TABS IN THIS FILE

Yeah Dave... I asked you what would cause a syntax error in a yaml file
after your rails
talk at a NFJS and you said you had no idea! ;-) Sorry, couldn't
resist...

Really though, a default comment in the yaml generator would save lots
of angst and
frustration (that syntax error so took the wind out of my sails that I
blew off rails for
a couple weeks).

Could be even simpler than Dave's idea: "NOTE: YAML DOES NOT ALLOW
TABS".

PS: It was a really good presentation though Dave....
