添加Linkedin身份验证时的迁移错误

Question

我试图在我的rails应用程序中使用Linkedin的api进行身份验证。我对rails非常陌生，所以我遵循了这个指南http://sourcey.com/rails-4-omniauth-using-devise-with-twitter-facebook-and-linkedin/

我尝试运行rake :迁移，但是得到了这个错误。完整的痕迹在下面。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，如果有人有一个更好的指南使用linkedin apis与rails，请分享！谢谢你的帮助！

environemnt.rb文件

require File.expand_path('../application', __FILE__)

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'
 }

Rails.application.initialize!

Answer 1

你的environment.rb确实是问题所在。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'
 }

在错误的地方。如果它的开发特定，它应该在application.rb或config/environments/development.rb中。
