添加Linkedin时发生迁移错误身份验证

Question

我正在尝试在我的Rails应用程序中使用Linkedin的api进行身份验证。我很新的轨道，所以我遵循本指南http://sourcey.com/rails-4-omniauth-using-devise-with-twitter-facebook-and-linkedin/

我试图运行rake db：migrate但得到此错误。完整的痕迹在下面。我还添加了environment.rb文件，因为我认为这是问题所在，但我不确定。此外，如果任何人有一个更好的指导，使用linkedin的apis与铁轨请分享！谢谢您的帮助！

environemnt .rb文件

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

config.app_domain = 'somedoamin.com'

config.action_mailer.perform_deliveries = true

Rails.application.initialize! 

Answer 1

您的environment.rb的确是问题所在。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' 
} 

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。
