添加Linkedin身份验证时迁移错误

Question

我正在尝试使用Linkedin的api在我的rails应用程序中进行身份验证。我对rails非常陌生，因此我遵循了本指南http://sourcey.com/rails-4-omniauth-using-devise-with-twitter-facebook-and-linkedin/

我试过运行rake db：migrate但是得到了这个错误。完整的痕迹如下。我还添加了environment.rb文件，因为我认为这就是问题所在，但我不确定。此外，如果有人有更好的指南使用带有rails的linkedin apis请分享！谢谢您的帮助！

Rails.application.initialize!

Answer 1

你的environment.rb确实是个问题。其中的所有配置代码：

config.app_domain = 'somedoamin.com'

config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.default_url_options = { host: config.app_domain }
config.action_mailer.smtp_settings = {
  address: 'smtp.gmail.com', 
  port: '587',
  enable_starttls_auto: true,
  user_name: 'someuser',
  password: 'somepass',
  authentication: :plain,
  domain: 'somedomain.com'
 }

是在错误的地方。如果它的开发具体，它应该在application.rb或config/environments/development.rb。
