Question

在我为Drupal 7构建的模块中，我正在尝试为安装和卸载过程创建数据库模式。当启用模块（并因此安装它）时，我收到错误，我的表格没有创建。

有人能看出哪里出错吗？

<?php
/**
 * Implementation of hook_schema().
 */
function wind_and_waves_schema() {
  $schema['wind_and_waves'] = array(
   'description' => 'Caches wind and waves data',
   'fields' => array(
     'id' => array(
       'description' => 'The unique identifier for this item.',

       'unsigned' => TRUE,
     ),
     'creation' => array(
       'description' => 'Moment the data has been loaded',
       'mysql_type' => 'datetime',
       'disp-width' => '11',
     ),
     'load_time' => array(
       'description' => 'Moment the wind data has been loaded by rijkswaterstaat',
       'mysql_type' => 'datetime',

     ),
     'hoek_wind_snelheid' => array(

       'disp-width' => '11',
     ),
     'hoek_golf_hoogte' => array(
       'description' => 'golfhoogte op hoek',

     ),
     'ijmuiden_wind_stoot' => array(
       'description' => 'Windstoot op ijmuiden',
       'type' => 'varchar',
       'disp-width' => '11',
     ),
     'ijmuiden_wind_richting' => array(
       'description' => 'Windrichting op ijmuiden',
       'type' => 'varchar',
       'disp-width' => '11',
     ),
     'ijmuiden_golf_hoogte' => array(
       'description' => 'golfhoogte op ijmuiden',
       'type' => 'varchar',
       'disp-width' => '11',
     ),
     'golf_periode' => array(
       'description' => 'golfperiode',
       'type' => 'varchar',

       'disp-width' => '11',
     ),
   ),
   'primary key' => array('id'),
  );
  return $schema;
}
?>

我得到的错误：

Answer 1

varchar类型的所有列都需要length属性，例如：

'luchttemp' => array(
   'description' => 'luchttemperatuur',
   'type' => 'varchar',
   'length' => 11
 )

disp-width仅对非varchar 类型列

有效

drupal db模式错误
