heroku上のDBをリセットする

More than 3 years have passed since last update.

heroku上でのDB操作

herokuで

rake db:reset
rake db:migrate:reset

のようにデータベースを操作する場合、

Running rake db:reset on ⬢ hidden-mountain-82613... up, run.9384 (Free)
FATAL:  permission denied for database "postgres"
DETAIL:  User does not have CONNECT privilege.
/app/vendor/bundle/ruby/2.2.0/gems/activerecord-4.2.5

となり、Permission deniedされてしまう。

そこで、herokuでDBを操作する場合は

heroku pg:reset DATABASE_URL

を行う。

その後

heroku run rake db:migrate
heroku run rake db:seed

などを行う。
