正在使用我的自定义邮件程序UserMailer发送电子邮件。它在开发中工作得很完美，但在生产中我得到错误500，就是在我忘记时检索密码的时候。
这是生产模式中生产日志中的内容
Processing by Devise::PasswordsController#create as HTML
Parameters: {"utf8"=>"✓","authenticity_token"=>"xxxxxxxxxxxxxxx", "user"=>{"email"=>"sam@gmail.com"}, "commit"=>"Send me r$
Completed 500 Internal Server Error in 2ms
NameError (uninitialized constant Devise::UserMailer):

devise (2.1.2) lib/devise.rb:256:in `get'
devise (2.1.2) lib/devise.rb:279:in `mailer'
我的邮件配置。 user_mailer.rb
class UserMailer < Devise::Mailer
default :from => "info@xxxxxxxx.com"
def signup_confirmation(user)
@user = user
mail :to => user.email, :subject=> "Thank you for signing with us"
end
# send password reset instructions
def reset_password_instructions(user)
@resource = user
mail(:to => @resource.email, :subject => "Reset password instructions", :tag => 'password-reset', :content_type => "text/html") do |format|
format.html { render "devise/mailer/reset_password_instructions" }
end
end
end
production.rb文件
config.action_mailer.default_url_options = { :host => 'https://xxxxxxxxxx.com' }
config.action_mailer.raise_delivery_errors = false
config.action_mailer.perform_deliveries = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => 'info@xxxxxxxx.com',
:user_name => 'yyyyyy',
:password => 'zzzzzzzz',
:authentication => 'plain',
:openssl_verify_mode => 'none',
:enable_starttls_auto => true
}

好的，从它看起来你的邮件看起来不对劲。特别是设置。默认情况下，您可以创建这样的邮件：
class UserMailer < ActionMailer::Base
default :from => DEFAULT_FROM
def registration_confirmation(user)
@user = user
@url = "http://localhost:3000/login"
mail(:to => user.email, :subject => "Registered")
end
end
我在你的例子中注意到的是你的行为：
class UserMailer < Devise::Mailer
你继承自Devise的Mailer实际上你不应该做任何这个！如果还没有，您可能还想查看config/initalizers/devise.rb and set the config.mailer_sender = example @ gmail.com`。所以我建议你做的就是让你的邮件看起来如下：
class UserMailer < ActionMailer::Base
default :from => "info@xxxxxxxx.com"
def signup_confirmation(user)
@user = user
mail :to => user.email, :subject=> "Thank you for signing with us"
end
另外一件事......我注意到您的默认网址是：config.action_mailer.default_url_options = { :host => 'https://xxxxxxxxxx.com' }不需要https所以它应该看起来像config.action_mailer.default_url_options = { :host => 'xxxxxxxxxx.com' }。因为当你试图发射任何东西时会发生的事情是https://https://https://xxxxxxxxxx.com。这是人们容易犯的错误。
我也相信原因可能是因为您没有设置负责发送电子邮件的班级。
可能解决问题的其他可能解决方案
请注意，在config/intializers/devise.rb中，有以下注释掉的行：
# Configure the class responsible to send e-mails.
# config.mailer = "Devise::Mailer"
取消注释并将其设置为您正在使用的类，以便它可以
config.mailer = "UserMailer" # UserMailer is your mailer class
同样在app / mailers / user_mailer.rb中你应该：
class UserMailer < ActionMailer::Base
include Devise::Mailers::Helpers
default from: "default@mydomain.com"
def confirmation_instructions(record)
devise_mail(record, :confirmation_instructions)
end
def reset_password_instructions(record)
devise_mail(record, :reset_password_instructions)
end
def unlock_instructions(record)
devise_mail(record, :unlock_instructions)
end
# you can then put any of your own methods here
end
也可能想要生成自己的观点：
rails generate devise:views
还将电子邮件模板从app / views / devise / mailer /移动到app / views / user_mailer /
mv app / views / devise / mailer / * app / views / user_mailer /

做任何事都@david说过。除了为设备更改此设置＆gt; 3.2.4
class UserMailer < ActionMailer::Base
include Devise::Mailers::Helpers
def confirmation_instructions(record, token, opts={})
@token = token
devise_mail(record, :confirmation_instructions, opts)
end
def reset_password_instructions(record, token, opts={})
@token = token
devise_mail(record, :reset_password_instructions, opts)
end
def unlock_instructions(record, token, opts={})
@token = token
devise_mail(record, :unlock_instructions, opts)
end
