使用hook_schema()添加表

Question

我计划在hook_schema的帮助下添加一个表.我已经定义了模式,并在我的模块中调用它.但是,没有创建架构.我哪里错了.我的sample2.install文件中有以下代码

    function sample2_schema(){
    $schema['mytable1'] = array(
    'description' => t('My table description'),
    'fields' => array(
     'mycolumn1' => array(
      'description' => t('My unique identifier'),
      'type' => 'serial',
      'unsigned' => true,
      'not null' => true,
      ), 
     'myvarchar' => array(
       'description' => t('My varchar'),
       'type' => 'varchar',
       'length' => 32,
       'not null' => true,
      ),
      'mytimestamp' => array(
        'description' => t('My timestamp'),
        'type' => 'int',
        'not null' => true,
      ),
    ),
    'indexes' => array(
      'myvarchar' => array('myvarchar'),
    ),
    'primary key' => array('mycolumn1'),
    'unique keys' => array(
       'mycolumn1' => array('mycolumn1'),
    ),
    );

    return $schema;
    }
      function sample2_install(){
    drupal_install_schema('sample2');
       }
      function sample2_uninstall(){
    drupal_uninstall_schema('sample2');
        }

要调用它,我在sample2.module文件中使用以下代码.

        $record = (object) NULL;
    $record->myvarchar = 'blah';
    $record->mytimestamp = strtotime('now');
    drupal_write_record('mytable1',$record);

这不会创建任何表.

Answer 1

如果在添加sample2_schema()和sample2_install()函数之前存在并启用了sample2模块,则需要将其卸载(不仅仅是禁用),然后再次安装/启用它.否则,Drupal不会使用你的hook_install().另一种解决方案是在hook_update_N()实现中安装模式.然后使用u pdate.php或drush updatedb运行更新代码.

function sample2_update_6001() {
  drupal_install_schema('sample2');
}
