syntax error, unexpected '\n', expecting tCOLON2 or '[' or '.'

急にdb:migrateしようとしたら怒られる様になった。

20130211061203_create_settings.rbを見ても特に普段と変わらない様子。

$rake db:migrate
rake aborted!
/Users/komuro/rails-demo/db/migrate/20130211061203_create_settings.rb:4: syntax error, unexpected '\n', expecting tCOLON2 or '[' or '.'

何だろうと思ったらどうやら

$ rails generate scaffold Setting accesskey:string, secretkey:string

設定のカンマ(,)がいらなかったようです。

そのような場合は一度作成した一式を削除しましょう。

$ rails destroy scaffold Setting

それから再度カンマ無しで作成。

$ rails generate scaffold Setting accesskey:string secretkey:string

Suddenly, db:migrate gave me a error (see below)

20130211061203_create_settings.rb doesn't look so strange from path..hmmm

$rake db:migrate
rake aborted!
/Users/komuro/rails-demo/db/migrate/20130211061203_create_settings.rb:4: syntax error, unexpected '\n', expecting tCOLON2 or '[' or '.'

I googled and found out that I typed comma when I generate scaffold.

$ rails generate scaffold Setting accesskey:string, secretkey:string

No comma!

If you type it with comma, delete scaffold first.

$ rails destroy scaffold Setting

Then type again w/o comma.

$ rails generate scaffold Setting accesskey:string secretkey:string
