PG :: InFailedSqlTransaction創建初始租戶

Question

我正在將Rails項目轉換為多租戶，並且正在使用Apartment 。

我按照他們的自述文件及其鏈接的視頻上的說明進行操作

我的apartment.rb看起來像這樣：

require 'apartment/elevators/subdomain'
Apartment.configure do |config|
  config.excluded_models = ['Project', 'User']
  config.tenant_names = lambda { Project.pluck :subdomain }
  config.use_schemas = true
  config.persistent_schemas = %w{ public }
end
Rails.application.config.middleware.use Apartment::Elevators::Subdomain

我的項目模型如下所示：

class Project < ApplicationRecord
  after_create :create_tenant

  private

  def create_tenant
    Apartment::Tenant.create(subdomain)
  end
end

我可以運行db：migrate和db：setup沒問題。 然后，它將在公共架構中創建我的所有表。

但是，當我嘗試創建一個新項目時，我得到了這一點（來自c軌）

我也注意到這個問題有一個類似的堆棧跟蹤，但解決方法沒有道理給我。

我正在使用：Ruby 2.3.1（2016-04-26補丁程序級別112）[x64-mingw32]公寓1.2.0 Rails 5.0.1

如果該日志值得信任，則似乎失敗：

SELECT  "ar_internal_metadata".* FROM "ar_internal_metadata" WHERE "ar_internal_metadata"."key" = $1 LIMIT $2  [["key", :environment], ["LIMIT", 1]]

您的db / schema.rb是否包含此表？ 這是Rails 5中的新系統表。
