When you upgrade an engine that has new migrations, how to run them?

I just updated refinerycms-news engine in my Gemfile from '~> 0.9.8' to :git => 'https://github.com/resolve/refinerycms-news.git', and now there is an error caused by开发者_StackOverflow中文版 a missing column. The migration to create the column can be found in the installed gem, but rake db:migrate does nothing. Is there another rake task or other step that will run it?

You'll have to follow this convention for Refinery CMS:

rails generate refinerycms_news
rake db:migrate

The generator copies only new migrations in and then rake db:migrate runs them.
