【问题描述】：

我正在尝试使用外键定义表之间的关系在 drupal 7. 我使用 hook_schema 和 hook_update 函数来定义和更新架构。我收到以下错误。

$schema['relationship] = array(
  'description' => 'The table for employee organisation relationship',
  'fields' => array(
      'rid' => array(
          'description' => 'The primary Identifier for a Relationship.',
          'type' => 'serial',
          'unsigned' => TRUE,
          'not null' => TRUE,
      ),
      'uid' => array(
          'description' => 'The primary Identifier for User/Employee',
          'type' => 'int',
          'unsigned' => TRUE,
          'not null' => FALSE,
          'default' => 0,
      ),
      'oid' => array(
          'description' => 'The department Identifier of employee employed',
          'type' => 'int',
          'unsigned' => TRUE,
          'not null' => FALSE,
          'default' => 0,
  ),
  'indexes' => array(
      'uid' => array('uid'),
     'oid' => array('oid'),
  ),    
 'foreign keys' => array(
     'uid' => array(
         'table' => 'users',
          'columns' => array('uid' => 'uid')
     ),
      'oid' => array(
       'table' => 'organization',
         'columns' => array('oid' => 'oid')
   ),
 ),
  'primary key' => array('rid'),
  )
);

【解决方案1】：

嗯，我自己解决了。我将这些键放在字段数组下。那真是太愚蠢了，我需要 2 个小时才能找到答案。决赛代码如下：

$schema['relationship] = array(
  'description' => 'The table for employee organisation relationship',
  'fields' => array(
      'rid' => array(
          'description' => 'The primary Identifier for a Relationship.',
          'type' => 'serial',
          'unsigned' => TRUE,
          'not null' => TRUE,
      ),
      'uid' => array(
          'description' => 'The primary Identifier for User/Employee',
          'type' => 'int',
          'unsigned' => TRUE,
          'not null' => FALSE,
          'default' => 0,
      ),
      'oid' => array(
          'description' => 'The department Identifier of employee employed',
          'type' => 'int',
          'unsigned' => TRUE,
          'not null' => FALSE,
          'default' => 0,
  ),  
  ),
'indexes' => array(
      'uid' => array('uid'),
     'oid' => array('oid'),
  ),    
 'foreign keys' => array(
     'uid' => array(
         'table' => 'users',
          'columns' => array('uid' => 'uid')
     ),
      'oid' => array(
       'table' => 'organization',
         'columns' => array('oid' => 'oid')
   ),
 ),
  'primary key' => array('rid'),
);
