Rails: Modifying a Model Generated by Scaffolding

Question

How do you modify a model you\'ve generated using modeling? For example, the model myModel originally had columns a, b and c, but I now want to add column d.

Answer 1

The best answer I've found so far is run this from your project root:

ruby script/generate migration add_d_column_to_myModel 

Then edit the new migration file located in db/migration to look something like:

  def self.up
    add_column :myModel, :d, :string
  end

  def self.down
    remove_column :myModel, :d
  end

The last step will be to update your views accordingly.
