Gemfile
完全な俺得アプリなのでソースを公開するつもりはありませんが*1、代わりにGemfileだけ公開します

Gemfileをidobata 風に書くのが最近のマイブームです

Rails4.2.0.rc2 + activeadminでハマったのでメモ
Rails4.2.0.rc2 + activeadmin だとアプリ作った当時ハマったのでメモ。
当時は4.2.0.rc2だったんですが、4.2.0.rc3でもたぶん同じじゃないかなぁと思います。
急いでる人のまとめ
Before
gem 'rails', '4.1.8' gem 'activeadmin', github: 'activeadmin', ref: '05c312'
After
gem 'rails', '4.2.0.rc2' gem 'activeadmin', github: 'activeadmin', ref: '05c312' gem 'inherited_resources', github: "Junyulive/inherited_resources", ref: "b65f0b5" gem 'responders', '~> 2.0.2'
やったこと
rails 4.1.8 -> 4.2.0.rc2
bundle update は成功したんだけど rake db:migrate:reset でこんなエラーが出た

rails 4.2.0で ActionController::Responder が消えてるのが原因っぽい
http://edgeguides.rubyonrails.org/4_2_release_notes.html#respond-with-class-level-respond-to
respondersの2.0系使えとのこと
respondersの2.0.2を入れた
Bundler could not find compatible versions for gem "responders":
In Gemfile:
activeadmin (>= 0) ruby depends on
inherited_resources (!= 1.5.0, ~> 1.4) ruby depends on
responders (~> 1.0) ruby
responders (2.0.2)
activeadminが依存してるgemでバージョンがコンフリクトしてた
rails4.2でも動くinherited_resourcesを探す
inherited_resourcesのforkされてるbranch一覧みたらrails 4.2対応してる人がいたのでありがたく使わせてもらう https://github.com/Junyulive/inherited_resources/commit/b65f0b55558125419f7d1287e98f39d41a7ea4e6
追伸
今回もまたLT大会で優勝できませんでした(´・ω・`)
