所以我正在构建一个应用程序（Rails 4）并实现订阅计划，工作流程如下：
创建一个帐户，创建帐户时，使用它创建所有者，并且还应该使用它创建计划。
这是创建帐户时的服务器输出：
SQL (0.5ms) INSERT INTO "users" ("email", "encrypted_password", "confirmation_token", "confirmation_sent_at", "f_name", "l_name", "date_of_birth", "created_at", "updated_at") VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9) RETURNING "id" [["email", "swilson@patrolvault.net"], ["encrypted_password", "$2a$11$ZFMl7BhZc3a.DnoyfiEuYO7bXqLeZ9smhhg4J.JaK00APGFdpVsgG"], ["confirmation_token", "LmdZXcuL7GJYP6nqWKvm"], ["confirmation_sent_at", 2016-10-19 02:19:21 UTC], ["f_name", "Some"], ["l_name", "Owner"], ["date_of_birth", Mon, 01 Jan 1900], ["created_at", 2016-10-19 02:19:21 UTC], ["updated_at", 2016-10-19 02:19:21 UTC]]
SQL (0.2ms) INSERT INTO "public"."accounts" ("subdomain", "owner_id", "created_at", "updated_at", "image_data") VALUES ($1, $2, $3, $4, $5) RETURNING "id" [["subdomain", "testdomain1"], ["owner_id", 1], ["created_at", 2016-10-19 02:19:21 UTC], ["updated_at", 2016-10-19 02:19:21 UTC], ["image_data", "{\"id\":\"536fe1bc4a8a95d64d81dd2e4f4e10af.png\",\"storage\":\"cache\",\"metadata\":{\"filename\":\"Pvaulticon.png\",\"size\":9419,\"mime_type\":\"image/png\"}}"]]

(0.4ms) COMMIT
(0.1ms) BEGIN
SQL (0.4ms) UPDATE "public"."accounts" SET "updated_at" = $1, "image_data" = $2 WHERE "public"."accounts"."id" = $3 [["updated_at", 2016-10-19 02:19:21 UTC], ["image_data", "{\"id\":\"299bf4eba233a14d65e94ea9d85893f6.png\",\"storage\":\"store\",\"metadata\":{\"filename\":\"Pvaulticon.png\",\"size\":9419,\"mime_type\":\"image/png\"}}"], ["id", 1]]
(6.3ms) COMMIT
但是，当我尝试在Rails控制台中查询计划时，它会返回：
2.3.1 :004 > Plan.all
Plan Load (0.2ms) SELECT "plans".* FROM "plans"
=> #<ActiveRecord::Relation []>
2.3.1 :007 > a.plan.plan_type
Plan Load (0.1ms) SELECT "plans".* FROM "plans" WHERE "plans"."account_id" = $1 LIMIT $2 [["account_id", 1], ["LIMIT", 1]]
NoMethodError: undefined method `plan_type' for nil:NilClass

以下是我的帐户模型：
class Account < ApplicationRecord
include ImageUploader[:image]
# Constants
RESTRICTED_SUBDOMAINS = %w(www patrolvault admin test type taurenapplabs taurenmaterialservices)
# Before Actions
before_validation :downcase_subdomain
# Relationships
belongs_to :owner, class_name: 'User', optional: true
accepts_nested_attributes_for :owner
has_many :users
# Validations
validates :owner, 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 domain name'}
has_one :plan
accepts_nested_attributes_for :plan
private
def downcase_subdomain
self.subdomain = self.subdomain.downcase
end
end
这是我的计划模型：
class Plan < ApplicationRecord
# Enum & Constants
enum plan_type: [:responder, :first_responder, :patrol_pro, :guardian]
USER_LIMITS = ActiveSupport::HashWithIndifferentAccess.new(
responder: 6,
first_responder: 12,
patrol_pro: 30,
guardian: 60
)
# Before Actions
# Relationships
belongs_to :account, optional: true
end
以下是帐户管理员：
class AccountsController < ApplicationController
skip_before_action :authenticate_user!, only: [:new, :create]
def new
@account = Account.new
@account.build_owner
@account.build_plan
end
def create
@account = Account.new(account_params)
respond_to do |format|
if @account.valid?
Apartment::Tenant.create(@account.subdomain)
Apartment::Tenant.switch!(@account.subdomain)
@account.save
format.html {redirect_to new_user_session_url(subdomain: @account.subdomain)}
else
format.html {render :new}
end
end
end
private
def account_params
params.require(:account).permit(:subdomain, :image, plan_attributes: [:plan_type, :id], owner_attributes: [:email, :password, :password_confirmation, :f_name, :l_name, :date_of_birth])
end
def set_account
@account = Account.find(params[:id])
end
end
和计划控制器：
class PlansController < ApplicationController
private
def plan_params
params.require(:plan).permit(:account_id, :plan_type)
end
end
答案 0 :(得分：1)
您的计划是否在帐户租户之外创建？我看到您在创建帐户后切换租户，因此可能会创建记录，但之后它不可见，因为它位于全球租户中
您可能需要计划成为一个全球模型，例如住在租户之外的帐户。
