在开发环境中跳过初始化程序 rails

Question

每当我在 cmd 行中执行 rails test 时，或者 rails db:migrate RAILS_ENV=test 尽管 rails 服务器工作正常，但我的 omniauth 初始化程序一直收到 NoMethodError，omniauth在我的 heroku 网站上，我的代码被推送到该网站。我阅读了这个问题 Rails: Per-environment initializers? 并在我的 omniauth 初始值设定项文件的顶部添加了 if Rails.env.production? 以便运行 omniauth 初始值设定项仅用于生产，但我没有运气。

完整的错误是；

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

Tasks: TOP => db:migrate => environment

有人知道这是为什么吗？

Answer 1

added if Rails.env.production? at the top of my omniauth initialzer file

仅将其添加到顶部不会有任何作用。 在条件

中包装你的逻辑

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