Hello ,

I am a ROR beginner. I have a controller named “users” and the  
corresponding view,model created using the command “ruby script/generate  
scaffold user name:string”.By running the command rake db:migrate will  
create the table “users” with a field “name” and the migration file  
created automatically is “001\_create\_users.rb”. Now when I tried to add  
one more column “password”  
by creating a new migration file using the command “ruby script/generate  
migration create\_users” and made the appropriate changes like  
“add\_column :users,:password,:string” in that file, an error is occuring  
like “Another file named 001\_create\_users.rb already exists”. May any  
one let me know what is the problem? I am using the right way or not?

Thanks in advance
