編輯：錯誤的原因（見下文）：我在doctrine_pi.php中的默認主鍵是「ID」，所以我將它改爲「book_id」（我的數據庫的主鍵）和它工作。感謝馬克·B.Doctrine CodeIgniter MySQL的CRUD錯誤
嗨， 我使用CI +學說+ MySQL和我得到以下CRUD錯誤：
（1）當試圖與這個代碼在數據庫中創建一個新的記錄：
$book_title = 'The Peloponnesian War';
$b = new Book();
$b->title = $book_title;
$b->price = 10.50;
$b->save();
我得到這個錯誤：
Fatal error: Uncaught exeption 'Doctrine_Connection_Mysql_Exception' with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'title' in 'field list' in ...
（2）當試圖對我的看法PA從數據庫中獲取和顯示記錄GE與此代碼：
$book_title = 'The Peloponnesian War';
$title = $book_title;
$search_results = Doctrine::getTable('Book')->findOneByTitle($title);
echo $search_results->title; //(in view file)
我得到這個錯誤：
Fatal error: Uncaught exception 'Doctrine_Connection_Mysql_Exception' with message 'SQLSTATE[45S22]: Column not found: 1054 Unknown column 'b.id' in 'field list" in ...
最後，當我嘗試如下更新記錄：
$book_title = 'The Peloponnesian War';
$title = $book_title;
$u = Doctrine::getTable('Book')->find($title);
$u->title = $title;
$u->save();
，我收到了類似的錯誤：
Fatal error: Uncaught exception 'Doctrine_Connection_Mysql_Exception' with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'b.id' in 'field list''in ...
這是我的Doctrine_Record m奧德爾：
class Book extends Doctrine_Record{
public function setTableDefinition()
{
$this->hasColumn('book_id');
$this->hasColumn('isbn10','varchar',20);
$this->hasColumn('isbn13','varchar',20);
$this->hasColumn('title','varchar',100);
$this->hasColumn('edition','varchar',20);
$this->hasColumn('author_f_name','varchar',20);
$this->hasColumn('author_m_name','varchar',20);
$this->hasColumn('author_l_name','varchar',20);
$this->hasColumn('cond','enum',null, array('values' => array('as new','very good','good','fair','poor')));
$this->hasColumn('price','decimal',8, array('scale' =>2));
$this->hasColumn('genre','varchar',20);
}
public function setUp()
{
$this->setTableName('Book');
//$this->actAs('Timestampable');
}
最後，這裏是我的mysqldump：

任何援助將非常感激。提前致謝。
+1感謝您的回覆Marc B.我做出了您所建議的更改並且我的第一個查詢正常運行！但是，我在'字段列表'的錯誤仍然爲第二個和第三個查詢得到1054未知列'b.id'，所以一些接縫與這些查詢錯誤... – Anthony 2010-04-24 06:16:43
沒有看到其餘的SQL錯誤，很難說，但由於你沒有一個名爲'b'的'id'字段的表，也許Doctrine期望你的書桌有一個'id'字段，但是你有'book_id' 。 – 2010-04-24 16:25:40
+1。你是正確的Marc B.我的doctrine_pi.php文件中的默認主鍵是「id」，所以我將它改爲「book_id」並刪除了這行：$ this-> hasColumn（'book_id'）;從我的教條模式，它的工作。謝謝 – Anthony 2010-04-25 16:07:31
