Rails Devise 推送到 Heroku:Errno::ECONNREFUSED(连接被拒绝 - connect(2)):

Rails Devise pushed to Heroku: Errno::ECONNREFUSED (Connection refused - connect(2)):

我正在完成我的学校作业。在这个阶段,我已经实施了 Devise 进行身份验证。整个项目对我来说在本地运行良好。当我推到 Heroku 时,这是另一个故事。这是应用程序的 link。 http://jonathanmusso-bloccit.herokuapp.com/

我第一次尝试 运行 Heroku 上的应用程序时收到此错误:

ActionView::Template::Error (Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true):

所以我在下面的 production.rb 中添加了最后 4 行。

config/environment/production.rb

Rails.application.configure do

end

目前我从 Heroku 日志中收到此错误:

Errno::ECONNREFUSED (Connection refused - connect(2)):

这是我的 development.rb

config/environment/development.rb

Rails.application.configure do

if Rails.env.development?
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
