I’m trying to deploy my first rails app on Heroku. I was using devise

  • 0

I’m trying to deploy my first rails app on Heroku. I was using devise for authentication, but my needs changed, so I removed it and am now using sorcery.

Everything is working locally, but when deploying I get the following message when migrating my DB:

Running `rake db:migrate` attached to terminal... up, run.5220
DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins! Support for these plugins will be removed in Rails 4.0. Move them out and bundle them in your Gemfile, or fold them in to your app as lib/myplugin/* and config/initializers/myplugin.rb. See the release notes for more on this: http://weblog.rubyonrails.org/2012/1/4/rails-3-2-0-rc2-has-been-released. (called from <top (required)> at /app/Rakefile:7)

I can’t seem to find any remaining mentions of Devise. Has anybody else run into a problem like this after removing the gem?

Thanks!

    You also need to remove the Devise initializer file /app/config/initializers/devise.rb.
