multi-tenant rails app user-account relationship issue - ruby-on-rails

Question

My application main gems: rails 4.1.1, pg, acts_as_tenant, devise and activeadmin.
Application description: saas multi-tenant app with subdomains (not using postgresql schemas).
I have 2 models: Account and User with:
account belongs_to :owner a class_name for User
user belongs_to :account and also acts_as_tenant(:account)
Note: if using acts_as_tenant, I am not sure I need to declare belongs_to?
On public domain (www.myapp.dev) user can create a new account and choose own subdomain. This user has the status of ‘owner’ for this particular subdomain/account. After account creation, user is redirected to custom subdomain for sign in. Once signed in, owner can create/invite other users to join his account.
On account creation, owner_id is correctly saved to account record. In ActiveAdmin I can filter my accounts by owners.
The problem is the account_id is not saved in the user record. Also in ActiveAdmin, when I try to edit the users records to add the account, the data is not saved…
I am learning Rails so please be easy :)
My Account model :
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
My User model :
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
Application Controller :
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
Account controller :
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
User controller :
class UsersController < ApplicationController
def index
#users = User.all
end
end
And my db schema :
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|

end

Answer 1

Try:
class Account < ActiveRecord::Base
has_one :account
...
class User < ActiveRecord::Base
acts_as_tenant(:account)
...
Without belongs_to for User model.
