Ejuicombobox在特定模型属性上抛出未定义的偏移错误
我使用自动完成功能下载了可编辑的组合框控件并添加了扩展名。我遇到了模型的patient_id和problem_definition_id属性的问题。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：
以下是我在视图中使用的代码：
$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),
));
以下是我的模特：

我曾经也为EJuiComboBox犯了同样的错误。只要没有找到DATA来提供组合框中的Textfield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，以防止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“未找到数据！”的简单渲染。只要ComboBox的数据中没有成员。

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，因此如果在数据库中将列标记为Not Null，则它将零（0）作为其默认值。当“$ this-＆gt; model-＆gt; {$ this-＆gt; attribute}”被执行时，它正在放置“0”而不是“problem_definition_id”，这就是抛出错误。在数据库中将列设置为Nullable后，错误消失了。但是，因为这似乎不是一个好的解决方案。因此，在创建$ PatientProblem对象后，我将problem_definition_id显式设置为null，并解决了错误。
