Question

我在尝试创建用户时在开发中遇到此错误。谁能告诉我我做错了什么？

users_controller.rb

  def create
    @user = User.new(user_params)
    if @user.save
      session[:user_id] = @user.id
      UserMailer.signup_confirmation(@user).deliver_now
      redirect_to user_tasks_path(current_user.id), notice: "Thank you for signing up!"
    else
      render "new"
    end
  end

environments/development.rb

Rails.application.configure do
  # Settings specified here will take precedence over those in config/application.rb.

  # In the development environment your application's code is reloaded on
  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.
  config.cache_classes = false

  # Do not eager load code on boot.
  config.eager_load = false

  # Show full error reports and disable caching.
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send.
  config.action_mailer.raise_delivery_errors = true

  config.action_mailer.delivery_method = :smtp

  config.action_mailer.smtp_settings = {
  adress: "smtp@gmail.com",
  port: 587,
  authentication: "plain",
  enable_starttls_auto: true,
  user_name: ENV["GMAIL_USERNAME"],
  password: ENV["GMAIL_PASSWORD"]
  }

  # Print deprecation notices to the Rails logger.
  config.active_support.deprecation = :log

  # Raise an error on page load if there are pending migrations.
  config.active_record.migration_error = :page_load

  # Debug mode disables concatenation and preprocessing of assets.
  # This option may cause significant delays in view rendering with a large
  # number of complex assets.
  config.assets.debug = true

  # Asset digests allow you to set far-future HTTP expiration dates on all assets,
  # yet still be able to expire them through the digest params.
  config.assets.digest = true

  # Adds additional error checking when serving assets at runtime.
  # Checks for improperly declared sprockets dependencies.
  # Raises helpful error messages.
  config.assets.raise_runtime_errors = true

  # Raises error for missing translations

end

class ApplicationMailer < ActionMailer::Base

    @user = user

    mail to: user.email, subject: "Sign Up Confirmation"

<%= @user.first_name %>,

Thank you for signing up!

在尝试投递邮件时，连接被 gmail 拒绝。我遇到了几乎相同的问题，最近我发现我没有在我的系统上启用 telnet 客户端来 ping gmail。所以我在我的系统（Windows 7）上启用了 telnet 客户端。还运行 telnet 测试以排除连接故障。我已按照此链接 [http://techblissonline.com/troubleshoot-gmail-smtp-server-connection/]http://techblissonline.com/troubleshoot-gmail-smtp-server-connection/ 进行 telnet 测试。如果您能够 ping gmail 并且仍然出现错误，请转到 gmail 设置并允许不太安全的应用程序访问您的帐户。
