Hi,
I have been trying to implement a HAS_MANY relationship for a while now and just cant seem to get it to work properly, data will display perfectly but i am unable to save back to the DB.
I keep receiving the following error when trying to save.
Fatal error: Call to a member function relations() on a non-object in C:\Program Files (x86)\EasyPHP-5.3.9\www\mysite\protected\extensions\wform\WForm.php on line 284
What I am building is a bird identification db, the update page has all the information about a particular type of bird, along with key points (BirdNotes) and a multiple images of the bird (Photos), the Photos table also has a relation to another table for storing the image itself.
I have gone through and looked at the example included but I am unable to make it work. The same error will appears no matter which HAS_MANY relationship I put on the form.
All models are standard as generated using Giix
Any help would be appreciated.
Here is my Relations in the Model
public function behaviors() {
return array(
// attach wform behavior
'wform' => array(
'class' => 'ext.wform.WFormBehavior',
// define relations which would be processed
'relations' => array('idNativity0', 'idProtection0', 'idHabitat0', 'BirdNotes', 'Photos'),
),
);
}
public function relations() {
return array(
'idNativity0' => array(self::BELONGS_TO, 'Nativity', 'idNativity'),
'idProtection0' => array(self::BELONGS_TO, 'Protection', 'idProtection'),
'idHabitat0' => array(self::BELONGS_TO, 'Habitat', 'idHabitat'),
'BirdNotes'=> array(self::HAS_MANY, 'BirdNote', 'idBird'),
'Photos'=> array(self::HAS_MANY, 'Photo', 'idBird'),
);
}
Here is my Controller
public function actionUpdate($id = null)
{
$model = $id ? Bird::model()->with('idNativity0', 'idProtection0', 'idHabitat0', 'BirdNotes', 'Photos')->findByPk($id) : new Bird();
$model=$this->loadModel($id);
if(isset($_POST['Bird']))
{
$model->attributes=$_POST['Bird'];
if($model->save()) {
$this->redirect(array('view','id'=>$model->idBird));
}
}
$this->render('update',array(
'model'=>$model,
));
}
Here is the Form for the BirdNote portion
<div class="row clearfix hasManyRelation">

<!-- exists items -->
<?php if ($model->BirdNotes): ?>
<?php foreach ($model->BirdNotes as $index => $item): ?>

--------- SOLVED ----------
Managed to locate the problem, for some reason the installation of PHP I have was not replacing the index variable in the string "BirdNotes.{$index}.Note" and putting in the index, neither that or "BirdNotes.$index.Note" worked, once I changed it to "BirdNotes." . $index . ".Note" everything came right.
I also added the following to line 284 of wForm.php, this will fix the array so that a CException is thrown for the invalid relation name, in my case it was throwing {index}
if (empty($model->relations)) { $model = array_shift(array_values($model)); }
