我在做什么
我最近在Multitenancy with Scopes(需要订阅)之后实施了多租户(使用范围)作为指导。注意:我 am 使用可怕的“default_scope”进行租户范围设定(如Ryan的Railscast所示)。一切都在浏览器中正常工作,但我的测试中很多(不是全部)都失败了,我无法弄清楚原因。
我从头开始构建身份验证(基于此Railscast:Authentication from Scratch (revised) - 需要订阅)并使用auth_token用于“记住我”功能(基于此Railscast:Remember Me & Reset Password)。
我的问题
为什么此测试失败,为什么这两个变通办法有效?我已经被困了几天了,只是想不出来。
我认为发生了什么
我正在调用Jobs #create操作,而Job.count 将减少而不是增加 1.我认为正在发生的事情是工作是正在创建,然后该应用程序正在失去“租户”任务(租户降至零),测试正在计算乔布斯为错误的租户。
奇怪的是,它期待“1”并获得“-1”(而不是“0”),这意味着它正在计算(注意在前一个块中已经创建了'种子'作业,所以它是在调用#create之前可能会计数“1”,调用create动作(应该将计数增加1到2),然后丢失租户并切换到零租户,其中有0个工作。所以它:
...导致Job.count发生-1变化。
您可以在下面看到,我已经通过在测试中将“.unscoped”添加到我的Job.count行来半确认了这一点。这意味着预期的工作岗位数量存在,但工作岗位不在应用程序正在测试的租户中。
我不明白的是它是如何失去租客的。
代码
我试图抓住我的代码的相关部分,并且我已经创建了一个专用的单一测试规范,以使其尽可能易于剖析。如果我可以做任何其他事情,以便在可能的回答者身上轻松完成,请告诉我该做什么!

如果我添加一些'puts'行来查看current_tenant是谁,并检查会话哈希,我会一直看到相同的租户ID:
describe "POST create" do
context "with valid attributes" do
it "creates a new job" do
expect{
puts current_tenant.id.to_s
puts session[:tenant_id]
post :create, job: FactoryGirl.attributes_for(:job)
puts current_tenant.id.to_s
puts session[:tenant_id]
}.to change(Job,:count).by(1)

我认为并不是RSpec忽略了默认范围,而是通过将当前用户设置为nil来重置在过滤器中的ApplicationController中。
我在分配(...)时遇到了这个问题,之所以发生这种情况,是因为当您评估分配时,实际上已经解决了这种关系。我认为在您的情况下也可能出现这种情况。
更新:在我的情况下,我能找到的最干净的解决方案(尽管我仍然讨厌它)是通过在测试环境中不将当前用户设置为nil来让默认范围泄漏。 / p>
在您的情况下,这相当于:
def scope_current_tenant
update_current_tenant
yield
ensure
Tenant.current_id = nil unless Rails.env == 'test'
end
我还没有使用您的代码对其进行测试,但这可能会有所帮助。

我设法让我的测试通过,虽然我仍然不确定为什么他们没有开始。这是我做的:
describe "POST create" do
context "with valid attributes" do
it "creates a new job" do
expect{ # <-- This is line 33 that's mentioned in the failure below
post :create, job: FactoryGirl.attributes_for(:job)
}.to change(Job.where(tenant_id: @tenant1.id),:count).by(1)
end
end
end
我改变了:
change(Job,:count).by(1)
...为:
change(Job.where(tenant_id: @tenant1.id),:count).by(1)
注意: @ tenant1是登录管理员的租户。
我假设default_scopes将应用于RSpec,但似乎它们不是(或者至少不在“expect”块的“:change”部分)。在这种情况下,Job的default_scope是:
default_scope { where(tenant_id: Tenant.current_id) }
事实上,如果我将该行更改为:
change(Job.where(tenant_id: Tenant.current_id),:count).by(1)
......它也会过去。因此,如果我在规范中明确模仿Job的default_scope,它就会通过。这似乎证实了RSpec在Jobs上忽略了我的default_scope。
在某种程度上,我认为我的新测试是确保租户数据保持隔离的更好方法,因为我明确地检查特定租户内的计数而不是隐式检查租户的计数(假设计数在“现有租户”)。
我说我的答案是正确的,因为这是唯一的答案,如果有人遇到这个问题,我想我的答案将帮助他们解决问题。也就是说,我真的没有回答我关于为什么测试失败的原始问题。如果有人知道为什么RSpec似乎忽略了“expect”块中的default_scope,那么这可能有助于使这个问题对其他人有用。

我和你们有同样的问题。我没有以一种让我感到舒服的方式解决问题,但仍然比验证你的RAILS_ENV更好。举个例子。
it "saves person" do
expect {
some_post_action
}.to change(Person, :count).by(1)
end
每次我尝试保存count方法时都会选择: &#34;从tenant_id为空的人员中选择计数(*)&#34;
我设法通过在更改方法中设置Person.unscoped来解决此问题,我改变了这个:
}.to change(Person, :count).by(1)
到此:
}.to change(Person.unscoped, :count).by(1)
这不是最佳解决方案,但我仍在努力寻找绕过default_scope的方法。
