我正在将我的 Rails 项目转换为多租户，并且正在使用Apartment。
我按照他们的自述文件和他们链接到的视频中的说明进行操作
我的apartment.rb样子是这样的：
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。然后它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）

我确实注意到这个问题与类似的堆栈跟踪，但解决方法对我来说没有意义。
