rubyonrails-talk

Hello, i am new to Ruby. question: i used scaffold to create a Database migration with lets say 2 fields: name:string surname:string

The scaffolding and migrationprocess has done the DB and the view edit delete action.

I want to add a new database field. I can do this in the migrationfile and the schema file and do the db migration again but the scaffolding part is not done again. Is there a way to do this automatically? Otherways i allways have to delete the Database and do all the scaffolding again and my changes made to the views are lost.

Any idea? tia

You'll want to create a new migration:

ruby script/generate migration <migration_name>

then edit the migration to add the field (descriptive migration naming will help you later)

run the migration and add that field to the index/edit/new views... no need to redo the database in total.

A Rails app is built of many migrations, which most see as a normal part of refactoring as new features or capabilities are added over time.

Thanks, so i have to add the new fields by hand to the view manually. The database thing is running fine. My question was about the manual changing the view/index/edit-files. So there is no way to do this automatically?
