模型保存在yii中不起作用，并且它没有重定向到查看页面

I am using following code in my controller. Have a look into that and let me know about the issue.

$model = new Model;

if (isset($_POST['Model'])) {  
    if ($model->save) {
        $this->redirect(array('view','id'=>$model->id));
    }
}

I can assume, you can try following change:

$model= new Model();
if(isset($_POST['Model'])){
    $model->attributes = $POST['Model']
    if($model->save)
        $this->redirect(array('view','id'=>$model->id));
}

$model= new Model();

if(Yii::app()->request->isPostRequest)
{
    $model->attributes = $_POST['Model']

    if($model->save)
        $this->redirect(array('view','id'=>$model->id));
}

There are a few issues with your code. First you are not setting the values of the model. Second. save is a function, not a variable

$model = new Model;

if (isset($_POST['Model'])) {
    // Fix 1. Save the details from the form to your model
    $model->setAttributes = $_POST['Model'];
    // Fix 2. Save is a function. Notice the ()
    if ($model->save()) {
        $this->redirect(array('view','id'=>$model->id));
    }
}
