cakephp 按不同分组

Question

我有一个表命令女巫包含一个日期，heure ...我想返回一个表，女巫按日期给我一个命令组，但我的问题是每个日期我都有一个命令，当我有多个命令时约会她是我的要求：

$factures = $this->Commande->find('all', array(

                    'conditions' => array(
                        'Commande.prestataire_id' => $this->request->data['prestataire_id']

                    ),
             'group' => array('Commande.date'),
                 'order' => array('Commande.date' => 'DESC'),
                 'fields' => array(' Commande.date'),
                ));

这是输出：

{
    "status": "Success",
    "status_code": 200,
    "message": "Commande trouvé",
    "data": {
        "everjob_get_Mission": {
            "data": [
                {
                    "Commande": {
                        "date": "2018-04-25"
                    }
                },
                {
                    "Commande": {
                        "date": "2018-04-24"
                    }
                },
                {
                    "Commande": {
                        "date": "2018-04-23"
                    }
                },
                {
                    "Commande": {
                        "date": "2018-04-19"
                    }
                },
                {
                    "Commande": {
                        "date": "2018-04-20"
                    }
                }
            ]
        }
    }
}

尝试下面的代码。我希望它对你的工作不确定。

$factures = $this->Commande->find('all', array(
        'fields' => 'DISTINCT Commande.date',
        'conditions' => array(
            'Commande.prestataire_id' => $this->request->data['prestataire_id']

        ),
    'group' => array('Commande.date'),
    'order' => array('Commande.date' => 'DESC')
));
