我在HABTM關聯中遇到了一些麻煩。HABTM加入表中的其他字段
我試圖做的是以下幾點:
模板HABTM中 頁面HABTM中
要做到這一點,我創建了連接表object_media
,並希望它有object_id
,medium_id
和model
領域。頁面ID或模板ID將進入object_id
字段,模型將具有「頁面」或「模板」。通過這樣做,我可以將任何模型與我的中型模型連接起來。 (媒體=媒體,所有圖像,視頻,文件等保存在那裏)。然後,我只需將條件傳遞給HABTM關係即可獲得該特定型號的媒體。例如:ObjectMedium.model => 'Template'
將返回連接到模板的所有媒體。
簡而言之:我想要1個表格將任何模型鏈接到任何媒介。
的template.php
class Template extends AppModel{
public $name = 'Template';
public $hasMany = array(
'TemplateColumn'
);
public $hasAndBelongsToMany = array(
'Medium' => array(
'className' => 'Medium',
'joinTable' => 'object_media',
'foreignKey' => 'object_id',
'associationForeignKey' => 'medium_id'
)
);
}
Medium.php
class Medium extends AppModel{
public $name = 'Medium';
public $useTable = 'media';
public $hasAndBelongsToMany = array(
'Template' => array(
'className' => 'Template',
'joinTable' => 'object_media',
'foreignKey' => 'medium_id',
'associationForeignKey' => 'object_id'
)
);
}
然而,餵養它下面的數據甚至不會保存介質:
Array
(
[Template] => Array
(
[name] =>
)
[TemplateColumn] => Array
(
[0] => Array
(
[block] => 0
[column] => 0
[grid] => 7
)
[1] => Array
(
[block] => 0
[column] => 1
[grid] => 5
)
[2] => Array
(
[block] => 1
[column] => 0
[grid] => 6
)
[3] => Array
(
[block] => 1
[column] => 1
[grid] => 6
)
)
[Medium] => Array
(
[0] => Array
(
[name] => 7917196b42c3626c10ab024bbafb8171
[src] => 134a16c2202ff2b0c9b1c51dddb1bcfc.jpg
[type] => Image
)
)
這給了我以下查詢:
INSERT INTO `templates` (`name`, `modified`, `created`) VALUES ('', '2011-11-20 15:18:46', '2011-11-20 15:18:46')
SELECT `ObjectMedium`.`medium_id` FROM `object_media` AS `ObjectMedium` WHERE `ObjectMedium`.`object_id` = 30
INSERT INTO `template_columns` (`block`, `column`, `grid`, `template_id`, `modified`, `created`) VALUES (0, 0, 7, 30, '2011-11-20 15:18:46', '2011-11-20 15:18:46')
INSERT INTO `template_columns` (`block`, `column`, `grid`, `template_id`, `modified`, `created`) VALUES (0, 1, 5, 30, '2011-11-20 15:18:46', '2011-11-20 15:18:46')
INSERT INTO `template_columns` (`block`, `column`, `grid`, `template_id`, `modified`, `created`) VALUES (1, 0, 6, 30, '2011-11-20 15:18:46', '2011-11-20 15:18:46')
INSERT INTO `template_columns` (`block`, `column`, `grid`, `template_id`, `modified`, `created`) VALUES (1, 1, 6, 30, '2011-11-20 15:18:46', '2011-11-20 15:18:46')
任何發生什麼問題的想法?以及如何在連接表中添加模型名稱?
