PG :: InFailedSqlTransaction创建初始租户

标签： ruby-on-rails apartment-gem

我正在将我的Rails项目转换为多租户，我正在使用Apartment。

我按照自述文件和the video they link to

上的说明进行操作

我的apartment.rb看起来像这样：

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

我的项目模型如下所示：

class Project < ApplicationRecord
  after_create :create_tenant

  private

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

我可以运行db：migrate和db：setup没问题。它然后在公共模式中创建我的所有表。

但是，当我尝试创建一个新项目时，我得到了这个（来自rails c）

我注意到this issue有类似的堆栈跟踪，但解决方法对我没有意义。

我正在使用： Ruby 2.3.1（2016-04-26 patchlevel 112）[x64-mingw32] 公寓1.2.0 Rails 5.0.1

如果要信任该日志，则它似乎失败了：

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

你的db / schema.rb是否包含这个表？它是Rails 5中的一个新系统表。
