rails，设计可恢复的不发送电子邮件

Question

我已经在我的 Rails 应用程序中进行了设计。我添加了可确认的，并发送了电子邮件以确认电子邮件帐户，并且它在开发环境中正确发送。

我也添加了可恢复选项：

  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, :confirmable

但是当我转到“忘记密码”并输入电子邮件时，它不会发送任何内容。我真的很难弄清楚为什么可恢复的电子邮件不起作用。我很确定这不是我的电子邮件设置，因为它可以确认。有人可以提供有关调试的任何想法吗？或者从哪里开始研究为什么可恢复无法正常工作？

非常感谢。

我在忘记密码时按下提交按钮时的日志：

这是我注册新用户时的日志（可确认）：

为什么无法恢复激活 devise::mailer？

我的用户.rb：

class User < ActiveRecord::Base

  extend FriendlyId
  friendly_id :username, use: [:slugged, :finders]

  def should_generate_new_friendly_id?
    username_changed?
  end

  #validates :username, :uniqueness => {:case_sensitive => false},
  #:format => { with: /\A[a-zA-Z0-9]+\Z/ }

  validates :firstname, presence: true
  validates :lastname, presence: true
  validates :country, presence: true
  validates :birthday, presence: true

  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, :confirmable

  attr_accessor :login

  validates_with AttachmentSizeValidator, :attributes => :avatar, :less_than => 1.megabytes

  acts_as_voter
  acts_as_messageable
  acts_as_votable
  is_impressionable

  has_attached_file :avatar, :styles => { 
      :medium => "300x300>", 
      :thumb => "100x100#", 
      :small => "50x50#",
      :tiny => "35x35>",
      :header => "30x30#" }, 
      default_url: ActionController::Base.helpers.image_path('silhouette.png')

  validates_attachment_content_type :avatar, :content_type => /\Aimage\/.*\Z/

   def self.find_first_by_auth_conditions(warden_conditions)
      conditions = warden_conditions.dup
      if login = conditions.delete(:login)
        where(conditions).where(["lower(username) = :value OR lower(email) = :value", { :value => login.downcase }]).first
      else
        where(conditions).first
      end
    end
end

Answer 1

您是否在用户表中添加了可恢复模块所需的正确字段？如果没有，则运行此迁移

class AddRecoverableToUsers < ActiveRecord::Migration
  def change
    add_column :users, :reset_password_token, :string
    add_column :users, :reset_password_sent_at, :datetime
  end
end

运行后重启服务器再试一次

或者，在devise/password/new.html.erb 中的form_for 标记内添加这些行，您将在视图中看到确切的错误

<% if f.object.errors.any? %>
  <ul>
    <% f.object.errors.full_messages.each do |msg| %>
      <li><%= msg %></li>
    <% end %>
  </ul>
<% end %>

所以，由于您的 username 字段正在产生问题，您可以添加一个 before_update 回调，试试这个

before_validation :check_for_reset_token, if: Proc.new{ |user| user.reset_password_token_changed? }

def check_for_reset_token
  self.username = username
end

Answer 2

只是为了确定一下，您能否确认这些步骤：

确认你的 config/environments/developement.rb 中有这个

   config.action_mailer.default_url_options = { host: 'localhost:3000' }
   config.action_mailer.delivery_method = :smtp
   config.action_mailer.perform_deliveries = true

您能否再次检查您在运行迁移时是否取消了所有这些行的注释：

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

我也会在 config/environments/developement.rb 中推荐这个

config.action_mailer.raise_delivery_errors = true
