Question

我的应用主要宝石：rails 4.1.1，pg，acts_as_tenant，devise和activeadmin。

应用程序描述：具有子域的saas多租户应用程序（不使用postgresql架构）我有2个模型：Account和User：

帐户belongs_to :owner用户的class_name
用户belongs_to :account以及acts_as_tenant(:account)

注意：如果使用acts_as_tenant，我不确定是否需要声明belongs_to？

在公共域（www.myapp.dev）上，用户可以创建一个新帐户并选择自己的子域。此用户具有此特定子域/帐户的“所有者”状态。创建帐户后，用户将被重定向到自定义子域以进行登录。登录后，所有者可以创建/邀请其他用户加入其帐户。

在创建帐户时，owner_id已正确保存到帐户记录中。在ActiveAdmin中，我可以按所有者过滤我的帐户。

问题是account_id未保存在用户记录中。同样在ActiveAdmin中，当我尝试编辑用户记录以添加帐户时，数据不会保存...

我正在学习Rails所以请轻松一下：）

我的帐户模型：

class Account < ActiveRecord::Base
  RESTRICTED_SUBDOMAINS = %w(www)
  belongs_to :owner, class_name: 'User'
  validates :owner, presence: true
  validates :name, presence: true
  validates :subdomain, presence: true,
                   uniqueness: { case_sensitive: false },
                   format: { with: /\A[\w\-]+\Z/i, message: 'contains invalid characters' },
                   exclusion: { in: RESTRICTED_SUBDOMAINS, message: 'restricted' }
  accepts_nested_attributes_for :owner
  before_validation :downcase_subdomain

  def self.current_id=(id)
    Thread.current[:account_id] = id
  end

  def self.current_id
    Thread.current[:account_id]
  end

  private
  def downcase_subdomain
    self.subdomain = subdomain.try(:downcase)
  end
end

我的用户模型：

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable
  belongs_to :account       
  acts_as_tenant(:account)
  validates :lastname, presence: true, allow_nil: false
  validates :firstname, presence: true, allow_nil: false
  validates :password, presence: true, allow_nil: false
  validates :email, presence: true, allow_nil: false #uniqueness: true,

  def to_s
    "#{firstname} #{lastname} (#{email})"
  end       
end

应用程序控制器：

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception

  before_filter :authenticate_user! #, :set_mailer_host
  before_filter :configure_permitted_parameters, if: :devise_controller?

  protected
  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:accept_invitation).concat([:firstname])
  end

  private
  def current_account
    @current_account ||= Account.find_by(subdomain: request.subdomain)
  end
  helper_method :current_account

  def after_sign_out_path_for(resource_or_scope)
    new_user_session_path
  end

  def after_invite_path_for(resource)
    users_path
  end
end

帐户管理员：

class AccountsController < ApplicationController
  skip_before_filter :authenticate_user!, only: [:new, :create]
  def new
    @account = Account.new
    @account.build_owner
  end

  def create
    @account = Account.new(account_params)
    if @account.valid?
      @account.save
      redirect_to new_user_session_url(subdomain: @account.subdomain)
    else
      render action: 'new'
    end
  end

private
  def account_params
    params.require(:account).permit(:subdomain, :name, owner_attributes: [:lastname, :firstname, :email, :password, :password_confirmation, :account_id])
  end
end

用户控制器：

class UsersController < ApplicationController
  def index
    @users = User.all
  end
end

我的数据库架构：

ActiveRecord::Schema.define(version: 20140619202210) do

  # These are extensions that must be enabled in order to support this database
  enable_extension "plpgsql"

  create_table "accounts", force: true do |t|

尝试：

class Account < ActiveRecord::Base
  has_one :account
...

class User < ActiveRecord::Base
  acts_as_tenant(:account)
...

belongs_to模型没有User。
