Rails單元測試 - 未定義的方法'用戶'

我一直在試圖弄清楚如何測試，但似乎沒有解決我的問題。每次我嘗試運行任何測試，我得到這個錯誤：Rails單元測試 - 未定義的方法'用戶'

NoMethodError: undefined method `users' for #<#<Class:0x00560775e00768>:0x00560775e00470>

我如何運行我的測試模型中：ruby test/models/plan_test.rb

我試圖運行的最基本的測試（與Rails給我作爲例子），所以它沒有鏈接到任何模型/夾具。我的模型：

require File.expand_path("../../test_helper", __FILE__) 

class PlanTest < ActiveSupport::TestCase 
    test "the truth" do 
    assert true 
    end 
end

我已經創建了一個空的測試數據庫也一樣，當我嘗試添加數據庫裏面的燈具，我得到了同樣的錯誤。

謝謝你看:)

編輯：跟蹤上夾具命令（rake db:fixtures:load RAILS_ENV=test --trace）：

能否請您發佈完整的堆棧跟蹤（不僅僅是錯誤信息）？因爲通常堆棧跟蹤會告訴你發生錯誤的確切文件和行，以及涉及調用該方法的所有方法。 – spickermann

我更新了問題。我無法追蹤單元測試，但我張貼了夾具錯誤。 –

看起來像問題是在您的燈具文件。你可以請張貼你的燈具嗎？或者在這些文件中搜索'用戶'並且只是發佈那個部分？ – spickermann

試試這個：

one: 
     email: [email protected] 
     name: Ioana1 
     password: MyString 
     verified: 1 
     token: MyString 
     remember_token: MyString 
     plan: p0 
     subscription_id: 1 
     subscription_next_bill_date: 
     email_hash: 1 
     referred_by_user: two (or the way you named the self reference) 
     subscription_status: deleted

檢查您是否有有效的模型文件，稱爲app/models/user.rb，並且如果您使用生成用戶模型或者如果您爲用戶表創建了遷移，那麼您將運行遷移。

RAILS_ENV=test rake db:migrate

你app/models/user.rb應包含在最低限度：

class User < ActiveRecord::Base 
end

更新：下面您的評論表示您已經刪除了遷移文件。你總是可以得到你的測試數據庫做耙分貝鏡像發展DB：測試：準備

我正在處理遺留數據庫時刪除了我的用戶模型遷移。這可能是問題嗎？（所以我的模式不反映我的數據庫） –

是的。由於錯誤'未定義的方法'用戶'它表明該類沒有被定義在任何地方。 – lacostenycoder

嘗試'rake db：test：prepare' – lacostenycoder
