另一個Location.count「沒有改變1

位置基本上是一個其他信息字段的地址，這是我的第一個應用程序，我跟着Hartl和其他人建立它，但忽略了我無法修復的失敗測試現在我試圖糾正這個問題，我查看了所有發現這個問題的帖子，但仍然無法弄清楚（最後討論）。該應用可以工作，我可以創建新的位置，所以我認爲錯誤是與測試另一個Location.count「沒有改變1

我不知道會發生什麼事情了這一點。

一個帖子，似乎相關"User.count" didn't change by 1 - Rails有不完整的yml-我三重檢查了我的，但也許還錯過了一些東西。

@ArtOfCode。在控制檯中創建（我認爲這是你問的）。而且，由於id是nil，它不會出現在數據庫中，你可能會在正確的軌道上：

irb(main):004:0> location = Location.create(address: "1 Address1", city: "Los Angeles", state: "California", longitude: 99.99, latitude: 99.99, extant: false, current_description: "MyString2", notes: "MyString24", source: "MyString", geocoded_with: "MyString", coords_not_locked: false, ref_link: "MyString", geom: "0101000020E61000008B187618938F5DC0C2189128B4064140") 
     (0.2ms) BEGIN 
     Location Exists (0.4ms) SELECT 1 AS one FROM "locations" WHERE "locations"."address" = '1 Address1' LIMIT 1 
     SQL (2.5ms) INSERT INTO "locations" ("address", "state", "longitude", "latitude", "extant", "current_description", "notes", "source", "geocoded_with", "coords_not_locked", "ref_link", "geom", "created_at", "updated_at") VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10, $11, $12, $13, $14) RETURNING "id" [["address", "1 Address1"], ["state", "California"], ["longitude", "99.99"], ["latitude", "99.99"], ["extant", "f"], ["current_description", "MyString2"], ["notes", "MyString24"], ["source", "MyString"], ["geocoded_with", "MyString"], ["coords_not_locked", "f"], ["ref_link", "MyString"], ["geom", "0101000020E61000008B187618938F5DC0C2189128B4064140"], ["created_at", "2017-03-05 20:00:28.246188"], ["updated_at", "2017-03-05 20:00:28.246188"]] 
     (2.1ms) COMMIT 
    #<Location:0x007fe851a9bac8> { 
         :id => 177, 
        :address => "1 Address1", 
         :city => "Los Angeles", 
         :state => "California",

       :updated_at => Sun, 05 Mar 2017 20:00:28 UTC +00:00, 
         :geom => "0101000020E61000008B187618938F5DC0C2189128B4064140", 
        :source => "MyString", 
       :geocoded_with => "MyString", 
      :coords_not_locked => false, 
        :ref_link => "MyString" 
    }

申請資料不完整，但你可以看到的位置here。目前不允許註冊，所以顯然創建不能使用。地址已超過100年，可能不會生成地理座標。稍後在PostGIS中創建geom。

我想有一個簡單的解決方案，但它暗示了我。 gem 'rails' , '4.2.7'和ruby '2.3.1'

同樣的結果（之前我曾嘗試過，但現在是結果）。 'FAIL [ 「test_should_create_location」，LocationsControllerTest，2017年2月28日12時02分08秒-0800]'' ＃test_should_create_location LocationsControllerTest（1488312128.41s）「Location.count」沒有通過1 預期變化：4 實際：3 test/controllers/locations_controller_test.rb：21：在的塊中''感謝您的迴應。 – Greg

您是否已驗證'create'調用確實*創建了記錄（即使用控制檯）？ – ArtOfCode

夾具自動創建數據庫條目。您的位置夾具one存在於數據庫中。

因此，當您嘗試創建新位置的帖子並指定...

post :create, location: { address: @location.address,

您試圖創建已存在的地址的位置，但

validates :address, length: { minimum: 5, maximum: 50 }, uniqueness: true

...指定的地址必須是唯一的，所以你嘗試發佈戰績無效，因爲它具有與現有記錄相同的地址。

在post :create通話只需更改地址使用`一個assert_difference 'Location.count'

謝謝。那樣做了。我不太清楚夾具是否被使用過兩次。一次用於創建新條目以及現有條目。測試需要更多的學習。再次感謝。我一直在對此進行抨擊一週。但我對調試的瞭解比以前更多。 – Greg
