在The Rails教程中遇到錯誤第8章

Question

我試過修復它，但無濟於事。我很確定我遵循了教程。這發生在Rails教程的第8章中。

以下是錯誤當我運行bundle exec rake test

感謝您的幫助。

Answer 1

它看起來像前兩個錯誤是在你的session_helper：您的設置定義@user = user(:microte)。

不清楚記憶測試中的錯誤是什麼;你分享的測試看起來很好。我建議您將代碼更改與教程中的內容進行比較，以查看造成這些錯誤的原因。

Answer 2

看起來像你試圖從你的燈具拉出user時出現錯誤。檢查您的fixtures/users.yml文件，看看您是否有microte用戶定義。它應該是這個樣子（只是一個例子）：

microte: 
    name: "Test User" 
    email: "test_user@example.com" 
    password_digest: <%= User.digest("password")%> 
    slug: <%= "Test User".parameterize %> 
    activated: true 

Answer 3

在本教程中，用戶提供的名稱是：michael 正如以前的其他人所指出的那樣，您寫了：microte。 在你的users.yml夾具中檢查你如何命名他，並確保它們匹配。

由於一些解釋：在測試的開始，有是準備你的測試設置的設置方法：

def setup 
    @user = users(:microte) 
    end 

你這裏實例用戶，放入燈具文件。
