Deleting attribute from previously created scaffold in Rails?

I created a scaffold with 3 attributes. I later decided I didn't need one of them. How would I remove it completely?

You should create a migration that removes the column (attribute) from that table (model) and then run rake db:migrate again. Read up more on changing tables with migrations:

http://guides.rubyonrails.org/migrations.html#changing-tables

Let me know if you get stuck and need more assistance.

You need something similar to this:

change_table :products do |t|
  t.remove :description
end

This removes the description column from the products table.

Of course, you will also need to edit your views etc. to reflect that change.
