Question

我无法更新CakePHP中的特定字段。下面的代码如下。当您运行class OrdemServico extends AppModel { public $name = "OrdemServico"; public $useTable = "ordens_servico"; public $belongsTo = array( "Cliente" => array( "className" => "Cliente", "foreignKey" => "id_cliente" ), "Responsavel" => array( "className" => "Usuario", "foreignKey" => "responsavel" ), "Equipamento" => array( "className" => "Equipamento", "foreignKey" => "equipamento" ), "ModoEntrega" => array( "className" => "ModoEntrega", "foreignKey" => "modo_entrega" ) ); } class OrdemServicoController extends AppController { public function cancelar() { try { $this->layout = "ajax"; $this->autoLayout = false; $data = $this->request->data; $id = $data["question"]["parameter"]; $destino = unserialize($data["question"]["callback"]); $this->OrdemServico->id = $id; $this->OrdemServico->saveField("OrdemServico.cancelado", true); $this->Dialog->alert("A ordem de serviço foi cancelada com sucesso."); $this->redirect($destino); } catch (Exception $ex) { $mensagem = "Ocorreu um erro no sistema ao atualizar a ordem de serviço."; $this->Dialog->error($mensagem, $ex->getMessage()); $this->redirect(array("action" => "index")); } }时，只是它不起作用。

question.ctp
<div id="dialog-question" class="modal-dialog">
<?php
echo $this->Form->create(null, array(
    "url" => array(
        "controller" => "ordem_servico",
        "action" => "cancelar"),
    "id" => $form_name,
    "role" => "form"
));

echo $this->Form->hidden("question.parameter");
echo $this->Form->hidden("question.callback", array("value" => serialize($retorno)));
?>

<div class="modal-content">
    <div class="modal-header" style="cursor: move">
        <button id="btn-question-close" type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title"><i class="fa fa-bell"></i>&nbsp;&nbsp;Sistema de Ordem de Serviço</h4>
    </div>
    <div class="modal-body">
        <p><?= h($message) ?></p>
    </div>
    <div class="modal-footer">
        <button id="btn-cancel-modal" type="button" class="btn btn-danger"><?= $buttons["cancel"] ?></button>
        <button id="btn-default-modal" type="submit" class="btn btn-success"><?= $buttons["ok"] ?></button>
    </div>
</div>
<?= $this->Form->end() ?>

}

我想知道发生了什么，因为系统无法以这种方式更新任何字段。

saveField需要字段名称

$this->OrdemServico->saveField("OrdemServico.cancelado", true);

saveField不期望以模型为前缀的字段名称。上面的语法等同于调用：

$this->OrdemServico->save([
    'OrdemServico' => [
        'id' => x,
        'OrdemServico.cancelado' => true
    ]
]);

那不会奏效。

要使用saveField，只需传递一个字段名称：

$this->OrdemServico->saveField("cancelado", true);

或者，请致电保存。

saveField不更新记录
