问题描述
我有以下架构(从带有 schema 模块 (7.x-1.0-beta3) 在自定义模块中.
I have the following schema (generated from an existing table with the schema module (7.x-1.0-beta3) in a custom module.
function myproject_entities_schema() {
// ---------------------------------------------------------------------------------
// MESSAGE
// ---------------------------------------------------------------------------------
$schema['myproject_entity_message'] = array(
'description' => 'The base table for myproject message instances',
'fields' => array(
'id' => array(
'description' => 'The primary identifier for a message instance',
'type' => 'serial',
'unsigned' => TRUE,
'not null' => TRUE,
),
'weekendday' => array(
'description' => 'Whether this message gets send on a weekendday(1) or on a workday(0)',
'type' => 'int',
'size' => 'tiny',
'not null' => TRUE,
'default' => 0,
),
'day' => array(
'description' => 'Numbered day of campaign schedule',
'type' => 'int',
'not null' => TRUE,
),
'content' => array(
'description' => 'Message content',
'type' => 'text',
'not null' => TRUE,

'type' => 'datetime',
'not null' => TRUE,
),
'campaign_fk' => array(
'description' => 'the foreign key of the campaign this message belongs to',
'type' => 'int',
'unsigned' => TRUE,
'not null' => FALSE,
),
'user_id' => array(
'description' => 'The user id this message is generated for',
'type' => 'int',
'unsigned' => TRUE,
'not null' => TRUE,
),
'pool_id' => array(
'description' => 'The pool node id this message was generated from',
'type' => 'int',
'unsigned' => TRUE,
'not null' => TRUE,
),
'message_template_id' => array(
'description' => 'The node id of the message template this message was generated from',
'type' => 'int',
'unsigned' => TRUE,
'not null' => TRUE,
),
),
'primary key' => array('id'),
'indexes' => array(
'CAMPAIGN' => array('campaign_fk'),
'MESSAGE_TEMPLATE' => array('message_template_id'),
'POOL' => array('pool_id'),
'USER' => array('user_id'),
),
);
// ---------------------------------------------------------------------------------
// CAMPAIGN
// ---------------------------------------------------------------------------------
$schema['myproject_entity_campaign'] = array(
'description' => 'The base table for myproject campaigns instances',
'fields' => array(
'id' => array(
'description' => 'The primary identifier for a campaign instance',
'type' => 'serial',
'unsigned' => TRUE,
'not null' => TRUE,
),
'schedule' => array(
'description' => 'The schedule of the campaign in text format.',
'type' => 'text',
'not null' => TRUE,
),
'interruptible' => array(
'description' => 'Whether this campaign is interruptible or not',
'type' => 'int',
'size' => 'tiny',
'not null' => TRUE,
),
'campaign_template_id' => array(
'description' => 'Node id of campaign template this instance was created from',
'type' => 'int',
'unsigned' => TRUE,
'not null' => TRUE,
),
'product_fk' => array(
'description' => 'Primary key of product instance this campaign belongs to',
'type' => 'int',
'unsigned' => TRUE,
'not null' => FALSE,
),
),
'primary key' => array('id'),
'indexes' => array(
'CAMPAIGN_TEMPLATE' => array('campaign_template_id'),
'PRODUCT' => array('product_fk'),
),
);
// ---------------------------------------------------------------------------------
// PRODUCT
// ---------------------------------------------------------------------------------
$schema['myproject_entity_product'] = array(
'description' => 'The base table for myproject product instances',
'fields' => array(
'id' => array(
'description' => 'The primary identifier for a product instance',
'type' => 'serial',
'unsigned' => TRUE,
'not null' => TRUE,
),
'start' => array(
'description' => 'Time when the campaign started',
'type' => 'datetime',
'not null' => TRUE,
),
'current_campaign_fk' => array(
'description' => 'Foreign key of currently running campaign instance',
'type' => 'int',
'unsigned' => TRUE,
'not null' => FALSE,
),
'next_campaign_fk' => array(
'description' => 'Foreign key of campaign instance to run next',
'type' => 'int',
'unsigned' => TRUE,
'not null' => FALSE,
),
),
'primary key' => array('id'),
'indexes' => array(
'CURRENT' => array('current_campaign_fk'),
'NEXT' => array('next_campaign_fk'),
),
);
return $schema;
}
当我尝试安装模块并因此创建架构时，我总是收到以下通知(我认为这不是失败的主要原因):
When i try to install the module and thus create the schema, I always get the following notice (which I dont think is the main reason for failing):
Notice: Undefined index: datetime:normal in DatabaseSchema_mysql->processField() (line 200 of /Users/xxx/Repos/myproject/includes/database/mysql/schema.inc).
还有以下错误:
PDOException: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'NOT NULL COMMENT 'When the message should arrive at the user', `campaign_fk` IN' at line 6: CREATE TABLE {myproject_entity_message} ( `id` INT unsigned NOT NULL auto_increment COMMENT 'The primary identifier for a message instance', `weekendday` TINYINT NOT NULL DEFAULT 0 COMMENT 'Whether this message gets send on a weekendday(1) or on a workday(0)', `day` INT NOT NULL COMMENT 'Numbered day of campaign schedule', `content` TEXT NOT NULL COMMENT 'Message content', `time_to_send` NOT NULL COMMENT 'When the message should arrive at the user', `campaign_fk` INT unsigned NULL DEFAULT NULL COMMENT 'the foreign key of the campaign this message belongs to', `user_id` INT unsigned NOT NULL COMMENT 'The user id this message is generated for', `pool_id` INT unsigned NOT NULL COMMENT 'The pool node id this message was generated from', `message_template_id` INT unsigned NOT NULL COMMENT 'The node id of the message template this message was generated from', PRIMARY KEY (`id`), INDEX `CAMPAIGN` (`campaign_fk`), INDEX `MESSAGE_TEMPLATE` (`message_template_id`), INDEX `POOL` (`pool_id`), INDEX `USER` (`user_id`) ) ENGINE = InnoDB DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci COMMENT 'The base table for myproject message instances'; Array ( ) in db_create_table() (line 2684 of /Users/xxx/Repos/myproject/includes/database/database.inc).
我搜索了架构定义中的错误，但找不到任何错误.我也不明白 sql 语句到底有什么问题.
I searched for errors in the schema definition but could not find any. Also I don't see what exactly is wrong with the sql statement.
我的服务器设置是:Apache/2.2.20 (Unix) mod_ssl/2.2.20 OpenSSL/0.9.8r DAV/2 PHP/5.3.6 with Suhosin-PatchMySQL 客户端版本:mysqlnd 5.0.8-dev - 20102224 - $Revision: 308673 $
My server setup is: Apache/2.2.20 (Unix) mod_ssl/2.2.20 OpenSSL/0.9.8r DAV/2 PHP/5.3.6 with Suhosin-Patch MySQL client version: mysqlnd 5.0.8-dev - 20102224 - $Revision: 308673 $
有人看到这里有什么问题吗?
Does anyone see whats wrong here?
推荐答案
我认为你需要使用 datetime:normal 作为你的 datetime 列类型.
I think you need to use datetime:normal as the key for your datetime column type.
'time_to_send' => array(
'description' => 'When the message should arrive at the user',
'type' => 'datetime:normal',
'not null' => TRUE,
),
除此之外，您可以尝试将列类型明确指定为 MySQL DATETIME:
Other than that you can try specifying the column type as a MySQL DATETIME explicitly:
'time_to_send' => array(
'description' => 'When the message should arrive at the user',
'mysql_type' => 'DATETIME',
'not null' => TRUE,
),
问题似乎源于在 Drupal 7 中实际上是否允许 DATETIME；请参阅此讨论了解更多细节，我无法在这里介绍:)
The problem seems to stem from whether or not DATETIME is actually allowed in Drupal 7; see this discussion for a lot more details than I can fit in here :)
