Phalcon 模型与附加条件具有多对多关系

Question

是否可以选择向 Phalcon 向导函数 hasManyToMany 添加附加条件？我检查了phalcon docs，但他们没有列出所有可能的 hasManyToMany 选项（仅列出别名和foreginKey）。 如果这不能通过 hasManyToMany 完成，是否还有其他 Phalcon 选项可用 - 例如。检索所有然后过滤一些模型加载事件？

简单示例： 我有 3 个表 Group、Relation 和 User，并且想使用 Relation 表在 User 模型中创建两个属性 - active_groups 和 inactive_groups。

代码：

class GroupModel extends Model {
    public $id;    
    public $name;
}

class RelationModel extends Model {
    public $id;    
    public $related_id_one;
    public $related_id_two;
    public $active;
}

class UserModel extends Model {

    public function initialize() {

        $this->hasManyToMany(
            "id",
            "RelationModel",
            "related_id_one",
            "related_id_two",
            "GroupModel",
            "id",
            array(  'alias' => 'active_groups', 
                    'conditions' => 'RelationModel.active = true')
        );

        $this->hasManyToMany(
            "id",
            "RelationModel",
            "related_id_one",
            "related_id_two",
            "GroupModel",
            "id",
            array(  'alias' => 'inactive_groups', 
                    'conditions' => 'RelationModel.active = false')
        );
    }
}

Tnx！

您可以改为这样做。顺便说一句，不完全确定这段代码是否正常运行，但希望你能明白。

我不知道 phalcon 是否有条件 / where 选项

class GroupModel extends Model {
    public $id;    
    public $name;
}

class RelationModel extends Model {
    public $id;    
    public $related_id_one;
    public $related_id_two;
    public $active;
}

class UserModel extends Model {

    public function initialize() {

        $this->hasManyToMany(
            "id",
            "RelationModel",
            "related_id_one",
            "related_id_two",
            "GroupModel",
            "id",
            array(  'alias' => 'groups')
        );

    }

    public function getActiveGroups() {
      return $this->getGroups('RelationModel.active = true');
    }

    public function getInactiveGroups() {
      return $this->getGroups('RelationModel.inactive = false');
    }
}
