Re: [Rails] Re: Re: My First Ruby App

Do you have Data in that table .if not please Delete that table and run migrations. then run ruby script/server
If you have data or you do not want to delete them put the new fields in table which you want to create and then You have to define  other fields in  in you MVC  separately that brings a lot of pain for you

hi rajeev
thanks for helping me out.
in the last section, i meant database.yml and not routes.rb. (my bad! it
was a slip of the tongue! )


I am in the prcess of re-reading your explanation.
At the first cut, as soon as i see the word migration, i feel like,...
"I don't want to do migration to my database. because, the columns exist
in my database already. "
Then why would  i do migration?


I know i am missing something here. can't figure out what it is.


thanks a ton !

radha.
