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" 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?

Once a migration is created with the scaffold command it cannot be altered with the scaffold command. Only manually. However, once a migration file has been used by running rake db:migrate, you are not recommended to alter this file in a real production site, but rather you must make a new migration file, but not using scaffold: script/generate migration AddPasswordColumn This command would create a new migration file where you can add/alter/ delete database columns and schema. However, if you are testing and want to redo your first scaffold command: rake db:migrate VERSION=0 And now edit the file and rerun: rake db:migrate Hank On Nov 26, 6:51 am, Indu RS <rails-mailing-l...-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> Hello , > > I am a ROR beginner.

Hi Indu
Did u start the project?
After running script/generate migration AddPasswordColumn you can do
like
In self.up
add_column :users,:password, :string
and may write in self.down (only if needed)
remove_column :users, :password
Then as usual rake db:migrate

Hi
Suppose there is a User model So in the view you have
<%= password_field ''user'', ''password''
%></p>
Now write in User model
before_create :protect_password
def protect_password
self.password = Digest::MD5.hexdigest(self.password)
end
There may be also other ways for doing this
