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

您的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'
 }

是在错误的地方。它应该在application.rb或config/environment/development.rb中，如果是特定于开发的。
