我有一个递归的多对多关系objective
。我的关系模型是:
CREATE TABLE master.objectives
(
id serial NOT NULL,
name character varying(100),
CONSTRAINT pkey_objectives PRIMARY KEY (id),
CONSTRAINT fk_objectives_perspective FOREIGN KEY (perspective_id)
REFERENCES master.perspective (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
)
CREATE TABLE master.relatedobjectives
(
parent integer NOT NULL,
child integer NOT NULL,
CONSTRAINT relatedobjectives_pkey PRIMARY KEY (parent, child),
CONSTRAINT fk_child_objectives FOREIGN KEY (child)
REFERENCES master.objectives (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION,
CONSTRAINT fk_paret_objectives FOREIGN KEY (parent)
REFERENCES master.objectives (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
)
我已经在 Yii 框架中使用 gii 生成了我的模型,如下所示:
目标.php
public function relations() {
// NOTE: you may need to adjust the relation name and the related
// class name for the relations automatically generated below.
return array(
'parents' => array(self::HAS_MANY, 'Relatedobjectives', 'parent'),
'children' => array(self::HAS_MANY, 'Relatedobjectives', 'child'),
);
}
目标/_form.php
<div class="row">
<?= $form->checkBoxList($model,'parents',
CHtml::listData(Objective::model()->findAll(array('order' => 'id')), 'id', 'name')
) ?>
</div>
在我提交表单时的视图中,不保存相关目标表中的关系。
我究竟做错了什么?
