我的应用程序有一个联系页面,用户可以在其中输入他们的姓名/电子邮件/主题/内容并向我发送消息。我正在使用 Heroku 的 Sendgrid 插件,并认为我几乎做对了所有事情。我有这个在我的
emails_controller.rb
if @email.save
ContactMailer.contact_message(@email).deliver
flash.now[:success] = "Your email has sent! I'll try to get back to you shortly."
render :new
else
flash.now[:error] = "Please correct the highlighted errors and try again."
render :new
end
(这里的想法是记录每封电子邮件并将其发送给我)。
我的配置/初始化程序/mail.rb
# SendGrid Settings
ActionMailer::Base.smtp_settings = {
:address => 'smtp.sendgrid.net',
:port => '587',
:authentication => :plain,
:enable_starttls_auto => true,
:user_name => ENV['SENDGRID_USERNAME'],
:password => ENV['SENDGRID_PASSWORD'],
:domain => 'myappname.com'
}
ActionMailer::Base.delivery_method = :smtp
然后,为了更好地衡量,遵循其他人在 sendgrid 支持问题中所做的事情。配置/环境/production.rb:
config.action_mailer.default_url_options = { :host => 'myappname.com' }
我的contact_email.html.erb:
class Contact < ActionMailer::Base
default from: "unimportant@example.com"
def contact_message(email)
@name = email.name
@address = email.address
@subject = email.subject
@content = email.content
mail(:to => ENV['EMAIL_ADDRESS'], :subject => @subject)
end
end
我通过添加了所有必要的环境变量
heroku config:add EMAIL_ADDRESS=blah@blah.com
heroku config:add SENDGRID_USERNAME=blah
但是,当我推到 heroku 并尝试给自己发送一封电子邮件时,它给了我“我们很抱歉。出了点问题”的死亡屏幕,并且日志(在我看来)完全没用。
这是从我上次推送到 heroku 并尝试向自己发送电子邮件时开始的日志。任何想法可能出了什么问题?

此外,我确实添加了 Sendgrid(按照 Heroku 的说明),并且 Sendgrid 用户界面显示未发送任何电子邮件。我最后一次尝试这个时,以下行似乎是 heroku 日志中唯一一个在我尝试发送另一条消息时带有相关时间戳的行。不是很有帮助:
