Question

前提・実現したいこと

現在gemのcarrierwaveを作成中のアプリに導入したい為、gemをインストール後、rails generate migration add_image_to_posts　image:stringでマイグレーションファイルを作成しようとしたのですがエラーが起きてしまいました。

Illegal name for migration file: add_image_to_posts　image:string
	(only lower case letters, numbers, and '_' allowed).

該当のソースコード

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
gem 'pry-rails'
gem 'haml-rails'
gem 'devise'
gem 'carrierwave'

試したこと

• マイグレーションファイルの名前をアッパーキャメルケースに変えてみました。

• bundleinstallをやり直してみました。

• カラム名をimageからimgに変更して試してみました。

Answer 1

rails generate migration add_image_to_posts　image:string

add_image_to_posts と image:string の間に全角スペースがあります。
半角スペースにしてください。
