Ejuicombobox 在特定模型属性上抛出未定义的偏移错误

Question

我下载了具有自动完成功能的可编辑组合框控件并添加了扩展名。我对模型的 Patient_id 和 Problem_definition_id 属性有问题。适用于 Problem_duration_id 和其他一些属性。当我将它们用于组合框时，我收到以下错误：

以下是我在我看来使用的代码：

$this->widget('ext.combobox.EJuiComboBox', array(
    'model' => $PatientProblem,
    'attribute' => 'problem_definition_id',
    'id'=>'eeed',
    'data'=>Yii::app()->cache->get('PATIENT_PROBLEM'),
    // options passed to plugin
    'assoc'=>true,
    'options' => array(
        'allowText' => false,),
    // Options passed to the text input
    'htmlOptions' => array('size' => 6),
));

以下是我的模型：

<?php

/**
 * This is the model class for table "patient_problem".
 *
 * The followings are the available columns in table 'patient_problem':
 * @property integer $problem_id
 * @property integer $problem_definition_id

 * @property integer $curr_or_history

 * @property string $problem_notes

我曾经对 EJuiComboBox 也遇到过同样的错误。每当没有找到数据来提供组合框中的文本字段时，就会发生这种情况，这是一个 PHP 错误。我对 EJuiComboBox 的 run 方法进行了以下更改，以阻止它在没有找到数据时抛出此 PHP 错误

public function run()
{
        list($name, $id) = $this->resolveNameID();

        if (is_array($this->data) && !empty($this->data)){
                //if $data is not an assoc array make each value its key
                $data=($this->assoc)?$this->data:array_combine($this->data, $this->data);

                //does the same as array_unshift($data,null) but does not break assoc arrays
                $data=array(""=>"")+$data;
        }

        else
                $data = array();

        if ($data == array()) {
            echo "No hay registros";
            return;
        }

        if ($this->hasModel())
                echo CHtml::activeDropDownList($this->model,$this->attribute,$data,$this->selectHtmlOptions);
        else
                echo CHtml::dropDownList($name, $this->value, $data,$this->selectHtmlOptions);

        echo CHtml::textField(null,($this->hasModel()?($data[$this->model->{$this->attribute}]):$data[$this->value]),array('id'=>$id.'_combobox'));

        $this->options = array_merge($this->defaultOptions, $this->options);

        $options = CJavaScript::encode($this->options);

        $cs = Yii::app()->getClientScript();

        $js = "combobox({$options});";

        list($id, $js) = $this->setSelector($id.'_combobox', $js);
        $cs->registerScript(__CLASS__ . '#' . $id, $js);
}

使用此方法将导致简单渲染“No data find!”每当 ComboBox 的数据中没有成员时。

我解决了这个问题。默认情况下，Yii 在运行时从数据库获取列的 Not Null 属性，因此如果数据库中将列标记为 Not Null，它将应用零 (0) 作为其默认值。当执行“$this->model->{$this->attribute}”时，它输入“0”而不是“problem_definition_id”，从而引发错误。将数据库中的列设为可为空后，错误消失了。但由于这似乎不是一个好的解决方案。因此，在创建 $PatientProblem 对象后，我显式地将 Problem_definition_id 设置为 null，并解决了错误。
