I saw the same problem posted earlier too on this group but still  
didnt find any solution…

I created a new database and a table.

when I tried the comman rake migration

it says

“Rake Aborted!  
Dont know how to build task ‘migrate’”

I donno wats wrong…

does anyone have any idea how to solve this???

My Database.yml file is

development:  
adapter: mysql  
database:railslist\_development  
username: root  
password: admin  
host: localhost  
timeout: 5000

adapter: mysql  
database: railslist\_test  
username: root  
password: admin  
host: localhost  
timeout: 5000

production:  
adapter: mysql  
database: railslist\_production  
username: root  
password: admin  
host: localhost  
timeout: 5000

Any help would be appreciated.

Thanks

Your info is out of date. It’s now rake db:migrate
