Hi
I recently installed Rails 3.1.1 on my ubuntu after lots of searching
on the web I managed to get my first app up and running on the local
server but I'm still getting "ActiveRecord::ConnectionNotEstablished"
error.
I ran my app on Root and I added my root password to the database.yml
file and I have everything installed.
I don't know what else to do.

help please.

Was it ok when you created the database (rake db:create) or if you did
not create it like that are you able to run migrations ok? (And are
you still able to run migrations ok).

running "rake db:create" returns 
rake aborted!
couldn't parse YAML at line 20 column 2

Tasks: TOP => db:create => db:load_config
(See full trace by running task with --trace)


at line 20 there's the "socket: /var/run/mysqld/mysqld.sock"

----
yaml is very whitespace sensitive

be sure that this line doesn't use 'tabs' and only a space

socket: /var/run/mysqld/mysqld.sock

Well there is something wrong with it. Has your password got any
funny characters in it? Alternatively retype a few lines around the
error and try again, possibly an unprintable char has got in there
somehow.

turned out I only needed to add a space between "password:" and "my password" 
that's all. 

thanks guys.
