Devise吐出与错误相关的消息：“确认令牌无效”并将用户带到重新发送确认电子邮件页面.

我正在托管heroku并使用sendgrid发送电子邮件.更新：该bug也发生在localhost上.

我不知道这个bug的根源在哪里,这可能比你需要看到的更多代码：

车型/ user.rb

...

devise :database_authenticatable,:registerable,:omniauthable,:recoverable,:rememberable,:trackable,:validatable,:confirmable,:authentication_keys => [:login]

...

## callbacks
after_create :account_created

# called after the account is first created
def account_created

  # check if this activiy has already been created
  if !self.activities.where(:kind => "created_account").blank?
    puts "WARNING: user ##{self.id} already has a created account activity!"
    return
  end

  # update points
  self.points += 50
  self.save

  # create activity
  act = self.activities.new
  act.kind = "created_account"
  act.created_at = self.created_at
  act.save

end

...

def confirmation_required?
  super && (self.standard_account? || self.email_changed)
end

控制器/ registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController
  def update
    unless @user.last_sign_in_at.nil?

      puts "--------------double checking whether password confirmation is required--"
      ## if the user has not signed in yet,we don't want to do this.

      @user = User.find(current_user.id)
      # uncomment if you want to require password for email change
      email_changed = @user.email != params[:user][:email]
      password_changed = !params[:user][:password].empty?

      # uncomment if you want to require password for email change
      # successfully_updated = if email_changed or password_changed

      successfully_updated = if password_changed
        params[:user].delete(:current_password) if params[:user][:current_password].blank?
        @user.update_with_password(params[:user])
      else
        params[:user].delete(:current_password)
        @user.update_without_password(params[:user])
      end

      if successfully_updated
        # Sign in the user bypassing validation in case his password changed
        sign_in @user,:bypass => true
        if email_changed
          flash[:blue] = "Your account has been updated! Check your email to confirm your new address. Until then,your email will remain unchanged."
        else
          flash[:blue] = "Account info has been updated!"
        end
        redirect_to edit_user_registration_path
      else
        render "edit"
      end
    end
  end
end

控制器/ omniauth_callbacks_controller

class OmniauthCallbacksController < Devise::OmniauthCallbacksController

  skip_before_filter :verify_authenticity_token

    def facebook
        user = User.from_omniauth(request.env["omniauth.auth"])
    if user.persisted?
      flash.notice = "Signed in!"

      # if the oauth_token is expired or nil,update it...
      if (DateTime.now > (user.oauth_expires_at || 99.years.ago) )
        user.update_oauth_token(request.env["omniauth.auth"])
      end

      sign_in_and_redirect user
    else
      session["devise.user_attributes"] = user.attributes
      redirect_to new_user_registration_url
    end
    end
end

配置/ routes.rb中

...

devise_for :users,controllers: {omniauth_callbacks: "omniauth_callbacks",:registrations => "registrations"}

...

如果需要,我很乐意提供更多信息.我也愿意定制/覆盖设计邮件程序的行为,但我不知道如何去做.

非常感谢！
