The model can be either an instance of {@link CModel} * or an associative array. * * CDetailView uses the {@link attributes} property to determines which model attributes * should be displayed and how they should be formatted. * * A typical usage of CDetailView is as follows: * <pre> * $this->widget('zii.widgets.CDetailView', array( * 'data'=>$model, * 'attributes'=>array( * 'title', // title attribute (in plain text) * 'owner.name', // an attribute of the related object "owner" * 'description:html', // description attribute in HTML * array( // related city displayed as a link * 'label'=>'City', * 'type'=>'raw', * 'value'=>CHtml::link(CHtml::encode($model->city->name), * array('city/view','id'=>$model->city->id)), * ), * ), * )); * </pre> * * @property CFormatter $formatter The formatter instance.

It can be either a property (e.g. "title") or a sub-property (e.g. "owner.username"). * * "Label" represents the label for the attribute display. If it is not given, "Name" will be used to generate the appropriate label. * * "Type" represents the type of the attribute. It determines how the attribute value should be formatted and displayed. * It is defaulted to be 'text'. * "Type" should be recognizable by the {@link formatter}. In particular, if "Type" is "xyz", then the "formatXyz" method * of {@link formatter} will be invoked to format the attribute value for display. By default when {@link CFormatter} is used, * these "Type" values are valid: raw, text, ntext, html, date, time, datetime, boolean, number, email, image, url. * For more details about these types, please refer to {@link CFormatter}. * * An attribute can also be specified in terms of an array with the following elements: * <ul> * <li>label: the label associated with the attribute. If this is not specified, the following "name" element * will be used to generate an appropriate label.</li> * <li>name: the name of the attribute. This can be either a property or a sub-property of the model. * If the below "value" element is specified, this will be ignored.</li> * <li>value: the value to be displayed. If this is not specified, the above "name" element will be used * to retrieve the corresponding attribute value for display. Note that this value will be formatted according * to the "type" option as described below. This can also be an anonymous function whose return value will be * used as a value. The signature of the function should be <code>function($data)</code> where data refers to * the {@link data} property of the detail view widget.</li> * <li>type: the type of the attribute that determines how the attribute value would be formatted. * Please see above for possible values. * <li>cssClass: the CSS class to be used for this item. This option is available since version 1.1.3.</li> * <li>template: the template used to render the attribute. If this is not specified, {@link itemTemplate} * will be used instead. For more details on how to set this option, please refer to {@link itemTemplate}. * This option is available since version 1.1.1.</li> * <li>visible: whether the attribute is visible. If set to <code>false</code>, the table row for the attribute will not be rendered. * This option is available since version 1.1.5.</li> * </ul> */ public $attributes; /** * @var string the text to be displayed when an attribute value is null.
