ruby-on-rails - 带有 MailCatcher 和 Devise gem 的 Rails 4

Question

我有一个带有 gem Devise 的应用程序。我需要通过电子邮件确认注册。在 config/environment.rb 我添加了这个

ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
   :address => "smtp.gmail.com",
   :port => 587,
   :domain => "gmail.com",
   :authentication => 'plain',
   :user_name => "myappname@gmail.com",
   :password => "mypassword"
}

在config/environment/development.rb中添加:

  config.action_mailer.default_url_options = { :host => 'localhost:3000' }
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = { :address => "127.0.0.1", :port => 1025 }

我想通过 gem MailCatcher 捕获所有电子邮件但是当我提交发送确认指令时，mailcatcher gem 中没有任何反应。但是在控制台中我有类似的东西:

Sent mail to abc@mail.ru (3757.4ms)

并且在 mailcathcer 中没有任何内容。怎么了？

Answer 1

这也发生在我身上。我关注了这些 awnser How do I set up email confirmation with Devise? .结果是我忘记在设计迁移中取消注释 confirmation_token 外键。之后，我删除并重新创建数据库并且工作正常!

因此，当您生成设计模型时，它会创建具有相应范围的以下迁移。

class DeviseCreateUsers < ActiveRecord::Migration
  def change
    create_table(:users) do |t|
      ## Database authenticatable
      t.string :email,              null: false, default: ""
      t.string :encrypted_password, null: false, default: ""

      ## Recoverable
      t.string   :reset_password_token
      t.datetime :reset_password_sent_at

      ## Rememberable
      t.datetime :remember_created_at

      ## Trackable
      t.integer  :sign_in_count, default: 0, null: false
      t.datetime :current_sign_in_at
      t.datetime :last_sign_in_at
      t.inet     :current_sign_in_ip
      t.inet     :last_sign_in_ip

      ## Confirmable
      # t.string   :confirmation_token
      # t.datetime :confirmed_at
      # t.datetime :confirmation_sent_at
      # t.string   :unconfirmed_email # Only if using reconfirmable

      ## Lockable
      # t.integer  :failed_attempts, default: 0, null: false # Only if lock strategy is :failed_attempts
      # t.string   :unlock_token # Only if unlock strategy is :email or :both
      # t.datetime :locked_at


      t.timestamps null: false
    end

    add_index :users, :email,                unique: true
    add_index :users, :reset_password_token, unique: true
    # add_index :users, :confirmation_token,   unique: true
    # add_index :users, :unlock_token,         unique: true
  end
end

要激活确认功能，您必须取消注释以下 block :

 ## Confirmable
 t.string   :confirmation_token
 t.datetime :confirmed_at
 t.datetime :confirmation_sent_at
 t.string   :unconfirmed_email # Only if using reconfirmable

和

add_index :users, :confirmation_token,   unique: true

这应该使电子邮件出现在 MailCatcher 中。

祝你好运:)
