所以我按照指南 - 步骤1 - 2.1.3。
我无法让系统发送电子邮件。这完全在我的开发环境中。
在我的用户控制器中，我编辑了创建操作，如下所示：
def create
@user = User.new(params[:user])
respond_to do |format|
if @user.save
UserMailer.welcome_email(@user).deliver
format.html { redirect_to(@user, :notice => 'User was successfully created.') }
format.xml { render :xml => @user, :status => :created, :location => @user }
else
format.html { render :action => "new" }
format.xml { render :xml => @user.errors, :status => :unprocessable_entity }
end
end
end
user_mailer.rb文件如下所示：
class UserMailer < ActionMailer::Base
default :from => "no-reply@mydomain.com"
def welcome_email(user)
@user = user
@url = "http://localhost.com:3000/users/login"
mail(:to => user.email, :subject => "Welcome to MySite")
end
end
我的/config/initializers/devise.rb文件如下所示：
Devise.setup do |config|
config.mailer_sender = "no-reply@mydomain.com"
# Configure the class responsible to send e-mails.
# config.mailer = "Devise::Mailer"
# ==> ORM configuration
# Load and configure the ORM. Supports :active_record (default) and
# :mongoid (bson_ext recommended) by default. Other ORMs may be
# available as additional gems.
require 'devise/orm/active_record'
# ==> Configuration for any authentication mechanism
# Configure which keys are used when authenticating an user. By default is
# just :email. You can configure it to use [:username, :subdomain], so for
# authenticating an user, both parameters are required. Remember that those
# parameters are used only when authenticating and not when retrieving from
# session. If you need permissions, you should implement that in a before filter.
config.authentication_keys = [ :username ]
# Tell if authentication through request.params is enabled. True by default.
# config.params_authenticatable = true
# Tell if authentication through HTTP Basic Auth is enabled. True by default.
# config.http_authenticatable = true
# Set this to true to use Basic Auth for AJAX requests. True by default.
# config.http_authenticatable_on_xhr = true
# The realm used in Http Basic Authentication
# config.http_authentication_realm = "Application"
# ==> Configuration for :database_authenticatable
# For bcrypt, this is the cost for hashing the password and defaults to 10. If
# using other encryptors, it sets how many times you want the password re-encrypted.
config.stretches = 10
# Define which will be the encryption algorithm. Devise also supports encryptors
# from others authentication tools as :clearance_sha1, :authlogic_sha512 (then
# you should set stretches above to 20 for default behavior) and :restful_authentication_sha1
# (then you should set stretches to 10, and copy REST_AUTH_SITE_KEY to pepper)
config.encryptor = :bcrypt
# Setup a pepper to generate the encrypted password.
config.pepper = "o27yo2oeb$2h2oiuhoiuKJH#KJ#K@JHLK@JHLKJLSKHGKJAgdskajgdkuyagdau"
# ==> Configuration for :confirmable
# The time you want to give your user to confirm his account. During this time
# he will be able to access your application without confirming. Default is nil.
# When confirm_within is zero, the user won't be able to sign in without confirming.
# You can use this to let your user access some features of your application
# without confirming the account, but blocking it after a certain period
# (ie 2 days).
# config.confirm_within = 2.days
# ==> Configuration for :rememberable
# The time the user will be remembered without asking for credentials again.
# config.remember_for = 2.weeks
# If true, a valid remember token can be re-used between multiple browsers.
# config.remember_across_browsers = true
# If true, extends the user's remember period when remembered via cookie.
# config.extend_remember_period = false
# ==> Configuration for :validatable
# Range for password length
# config.password_length = 6..20
# Regex to use to validate the email address
# config.email_regexp = /^([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})$/i
# ==> Configuration for :timeoutable
# The time you want to timeout the user session without activity. After this
# time the user will be asked for credentials again.
# config.timeout_in = 10.minutes
# ==> Configuration for :lockable
# Defines which strategy will be used to lock an account.
# :failed_attempts = Locks an account after a number of failed attempts to sign in.
# :none = No lock strategy. You should handle locking by yourself.
# config.lock_strategy = :failed_attempts
# Defines which strategy will be used to unlock an account.
# :email = Sends an unlock link to the user email
# :time = Re-enables login after a certain amount of time (see :unlock_in below)
# :both = Enables both strategies
# :none = No unlock strategy. You should handle unlocking by yourself.
# config.unlock_strategy = :both
# Number of authentication tries before locking an account if lock_strategy
# is failed attempts.
# config.maximum_attempts = 20
# Time interval to unlock the account if :time is enabled as unlock_strategy.
# config.unlock_in = 1.hour
# ==> Configuration for :token_authenticatable
# Defines name of the authentication token params key
# config.token_authentication_key = :auth_token
# ==> Scopes configuration
# Turn scoped views on. Before rendering "sessions/new", it will first check for
# "users/sessions/new". It's turned off by default because it's slower if you
# are using only default views.
# config.scoped_views = true
# Configure the default scope given to Warden. By default it's the first
# devise role declared in your routes.
# config.default_scope = :user
# Configure sign_out behavior.
# By default sign_out is scoped (i.e. /users/sign_out affects only :user scope).
# In case of sign_out_all_scopes set to true any logout action will sign out all active scopes.
# config.sign_out_all_scopes = false
# ==> Navigation configuration
# Lists the formats that should be treated as navigational. Formats like
# :html, should redirect to the sign in page when the user does not have
# access, but formats like :xml or :json, should return 401.
# If you have any extra navigational formats, like :iphone or :mobile, you
# should add them to the navigational formats lists. Default is [:html]
# config.navigational_formats = [:html, :iphone]
# ==> Warden configuration
# If you want to use other strategies, that are not (yet) supported by Devise,
# you can configure them inside the config.warden block. The example below
# allows you to setup OAuth, using http://github.com/roman/warden_oauth
#
# config.warden do |manager|
# manager.oauth(:twitter) do |twitter|
# twitter.consumer_secret = <YOUR CONSUMER SECRET>
# twitter.consumer_key = <YOUR CONSUMER KEY>
# twitter.options :site => 'http://twitter.com'
# end
# manager.default_strategies(:scope => :user).unshift :twitter_oauth
# end
end
我的应用程序控制器：
class ApplicationController < ActionController::Base
helper :all
protect_from_forgery
before_filter :set_current_user
protected
def set_current_user
Authorization.current_user = current_user
end
end
我注册新用户时从日志输出（顺便说一下，我已经注释掉了config_action.mailer_raise.delivery行）。

当我注册一个新用户时，它会创建用户并允许我登录 - 但我从未在收件箱中收到该电子邮件。
帮助！

尝试在config / environments / development.rb中添加这些行：
config.action_mailer.perform_deliveries = true
config.action_mailer.delivery_method = :sendmail #:smtp
