Askeet教程所遇问题备忘

      在根据Askeet教程学习Symfony时，有遇到这样一个问题：Unable to find path for class "francoisPeer"，笔者经过仔细研究，终于发现问题所在。

错误代码：

   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:

  13: #1 D:/workspace/askeet/batch/load_data.php(24): sfPropelData->loadData('D:/workspace/as...')

这个错误是test_data.yml文件格式书写错误导致的。因为直接拷贝网页上给出的yaml代码会有多余的空格，而yaml文件正是有空格控制格式的，所以要严格按照规范书写。
