我刚开始使用公寓，我想开发一种可以根据共享秘密工作的电梯。然而，我最初的测试并不乐观。

我现在所处的位置是：

app/middleware/static_elevator.rb

require 'apartment/elevators/generic'

class StaticElevator < Apartment::Elevators::Generic

  # @return {String} - The tenant to switch to
  def parse_tenant_name(request)
    # request is an instance of Rack::Request

    'my_schema_name'
  end
end

和：

config/initializers/apartment.rb

require 'apartment/elevators/generic'
# require 'apartment/elevators/domain'
#require 'apartment/elevators/subdomain'    
#
# Apartment Configuration
#
Apartment.configure do |config|

  config.tenant_names = lambda { Account.pluck(:schema) }

end

Rails.application.config.middleware.use 'StaticElevator'

所以本质上，每次请求进入数据库时​​，都会使用 my_schema_name 作为模式。在我的控制器中，我有：

class V1::StaffController < ApplicationController
  def index
    @staff = Staff.only_employees
  end
end

我的测试是：

require 'rails_helper'

RSpec.describe V1::StaffController, type: :controller do
  context 'no query string' do
    subject { get :index }

    it 'gets only the employees' do
      expect(Staff).to receive(:only_employees).and_return([])
      subject
    end
  end
end

当我运行测试时，我得到：

Randomized with seed 63457

V1::StaffController
  no query string
    gets only the employees (FAILED - 1)

Failures:

  1) V1::StaffController no query string gets only the employees
     Failure/Error: expect(Staff).to receive(:only_employees).and_return([])

       PG::UndefinedTable: ERROR:  relation "users" does not exist

                                                 ^
       :               SELECT a.attname, format_type(a.atttypid, a.atttypmod),
                            pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod
                       FROM pg_attribute a LEFT JOIN pg_attrdef d
                         ON a.attrelid = d.adrelid AND a.attnum = d.adnum
                      WHERE a.attrelid = '"users"'::regclass
                        AND a.attnum > 0 AND NOT a.attisdropped
                      ORDER BY a.attnum
     # ./spec/controllers/v1/staff_controller_spec.rb:8:in `block (3 levels) in <top (required)>'
     # ------------------
     # --- Caused by: ---

  V1::StaffController no query string gets only the employees
    0.01605 seconds ./spec/controllers/v1/staff_controller_spec.rb:7

1 example, 1 failure

这对我说架构没有运行。我对么？如果是这样，我做错了什么？

看起来您的测试数据库尚未正确迁移。

跑步后会发生什么

bundle exec rake db:migrate RAILS_ENV=test

另外：在您的示例中，您仅在 parse_tenant_name 中返回一个静态字符串，这应该是动态的，例如当您将租户名称存储在 request.session [：key] 中时。

根据您的配置，此租户名称也应该出现在 Account.pluck(:schema) 中。

因此，即使您已经在数据库中拥有架构，您似乎也需要一个 schema.rb 供 rspec 使用。一旦我提供了一个 db/schema.rb 突然间一切都很好，并且公寓（以及随之而来的测试）按预期运行。

您至少可以将这部分归咎于操作员过度自信:)
