Rails g migrationコマンドでカラムの追加が反映されていない？

Question

rails g modelコマンドを実行しモデルとマイグレーションファイルを作成し、作成したマイグレーションファイルに追加したいカラムを追記し、rails g migrationコマンドを実行しました。
下記のコードは、作成したマイグレーションファイルにカラムを追加する記述と、ターミナルでのrails g migrationコマンドを実行したものです。

class CreateArticles < ActiveRecord::Migration[6.0]
  def change
    create_table :articles do |t|
      t.date :dating
      t.string :title
      t.text :text
      
      t.timestamps
    end
  end
end

rooter:portfolio apple$ rails g migration
Running via Spring preloader in process 6990
Usage:
  rails generate migration NAME [field[:type][:index] field[:type][:index]] [options]

Options:
      [--skip-namespace], [--no-skip-namespace]  # Skip namespace (affects only isolated applications)
  -o, --orm=NAME                                 # ORM to be invoked
                                                 # Default: active_record

ActiveRecord options:
      [--primary-key-type=PRIMARY_KEY_TYPE]  # The type for primary key
  --db, [--database=DATABASE]                # The database for your migration. By default, the current environment's primary database is used.

Runtime options:
  -f, [--force]                    # Overwrite files that already exist
  -p, [--pretend], [--no-pretend]  # Run but do not make any changes
  -q, [--quiet], [--no-quiet]      # Suppress status output
  -s, [--skip], [--no-skip]        # Skip files that already exist

Description:
    Stubs out a new database migration. Pass the migration name, either
    CamelCased or under_scored, and an optional list of attribute pairs as arguments.

    A migration class is generated in db/migrate prefixed by a timestamp of the current date and time.

    You can name your migration in either of these formats to generate add/remove
    column lines from supplied attributes: AddColumnsToTable or RemoveColumnsFromTable

Example:
    `rails generate migration AddSslFlag`

    If the current date is May 14, 2008 and the current time 09:09:12, this creates the AddSslFlag migration
    db/migrate/20080514090912_add_ssl_flag.rb

    `rails generate migration AddTitleBodyToPost title:string body:text published:boolean`

    This will create the AddTitleBodyToPost in db/migrate/20080514090912_add_title_body_to_post.rb with this in the Change migration:

      add_column :posts, :title, :string
      add_column :posts, :body, :text
      add_column :posts, :published, :boolean

Migration names containing JoinTable will generate join tables for use with
has_and_belongs_to_many associations.

Example:
    `rails g migration CreateMediaJoinTable artists musics:uniq`

    will create the migration

    create_join_table :artists, :musics do |t|
      # t.index [:artist_id, :music_id]
      t.index [:music_id, :artist_id], unique: true
    end
