Askeet教程所遇問題備忘

      在根據Askeet教程學習Symfony時，有遇到這樣一個問題：Unable to find path for class "francoisPeer"，筆者經過仔細研究，終於發現問題所在。

錯誤代碼：

   1: D:/workspace/askeet/batch>php load_data.php 

   2: PHP Fatal error:  Uncaught exception 'sfException' with message 'Unable to find path for class "francoisPeer".' in D:/workspace/askeet/lib/vender/symfony/lib/ad on/propel/sfPropelData.class.php:206 

   3: Stack trace: 

   4: #0 D:/workspace/askeet/lib/vender/symfony/lib/addon/propel/sfPropelData.class.php(46): sfPropelData->doDeleteCurrentData(Array) 

   5: #1 D:/workspace/askeet/batch/load_data.php(24): sfPropelData->loadData('D:/workspace/as...') 

   6: #2 {main} 

   7:   thrown in D:/workspace/askeet/lib/vender/symfony/lib/addon/propel/sfPropelData 

   8: .class.php on line 206

   9:  

  10: Fatal error: Uncaught exception 'sfException' with message 'Unable to find path for class "francoisPeer".' in D:/workspace/askeet/lib/vender/symfony/lib/addon/propel/sfPropelData.class.php:206 

  11: Stack trace:

這個錯誤是test_data.yml文件格式書寫錯誤導致的。因爲直接拷貝網頁上給出的yaml代碼會有多餘的空格，而yaml文件正是有空格控制格式的，所以要嚴格按照規範書寫。
