PG :: InFailedSqlTransaction創建初始租戶

Question

我正在將我的Rails項目轉換爲多租戶，並且我正在使用Apartment。

我跟着他們的自述和方向the video they link to

我apartment.rb看起來是這樣的：

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 

我的項目模式是這樣的：

class Project < ApplicationRecord 
    after_create :create_tenant 

    private 

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

我可以運行分貝：遷移和db：setup沒有問題。它隨後在公共架構中創建我的所有表。

但是，當我嘗試創建一個新的項目，我得到這個（從軌三）

我也注意到this issue具有相似的堆棧跟蹤，但解決方法沒有道理給我。

我使用： 紅寶石2.3.1（2016年4月26日PATCHLEVEL 112）[x64的的mingw32] 公寓1.2.0 滑軌5.0.1

如果該日誌將被信任，它似乎失敗：

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中的一個新系統表。
