開発環境のイニシャライザをスキップする

Question

いつでも、私はコマンドラインでrails testを実行するか、rails db:migrate RAILS_ENV=test私はomniauthイニシャライザでNoMethodErrorを取得し続けますが、レールサーバは正常に動作しますが、omniauthは私のherokuサイトにプッシュされます。私はこの質問Rails: Per-environment initializers?を読んで、私のomniauth initialzerファイルの先頭にif Rails.env.production?を追加したので、omniauth initialzerをプロダクション用に実行するだけでしたが、私は運がないです。

完全なエラーは次のとおりです。

db:migrate RAILS_ENV=test --trace 
** Invoke db:migrate (first_time) 
** Invoke environment (first_time) 
** Execute environment 
rails aborted! 
NoMethodError: undefined method `[]' for nil:NilClass

これはどのような理由がありますか？

Answer 1

Rails.env.production？ omn​​iauth initialzerファイルの先頭にある

トップに追加するだけで何も起こりません。 ラップあなたのロジックは条件付き

if Rails.env.production? 
    # your omniauth stuff 
end
