I have followed the book up until this point without too much problem, but this problem I can’t figure out. I am at the end of Chapter 6. When I click on Update Issue, it seems the site would render fine but when it gets to Owner, it gives me the PHP error:
Fatal error: Call to a member function getUserOptions() on a non-object in C:\wamp\www\trackstar\protected\views\issue\_form.php
The form worked fine for creating issue, I don’t know why it fails for update. Since I access the link to update from view, here is my menu from views/issue/update.php:
$this->menu=array(
array('label'=>'List Issue', 'url'=>array('index','pid'=>$model->project->id)),
array('label'=>'Create Issue', 'url'=>array('create','pid'=>$model->project->id)),
array('label'=>'Update Issue', 'url'=>array('update', 'id'=>$model->id)),
array('label'=>'Delete Issue', 'url'=>'#', 'linkOptions'=>array('submit'=>array('delete','id'=>$model->id),'confirm'=>'Are you sure you want to delete this item?')),
array('label'=>'Manage Issue', 'url'=>array('admin','pid'=>$model->project->id)),
);
This is views/issue/update.php:
<?php
$this->breadcrumbs=array(
'Issues'=>array('index'),
$model->name=>array('view','id'=>$model->id),
'Update',
);
$this->menu=array(
array('label'=>'List Issue', 'url'=>array('index')),
array('label'=>'Create Issue', 'url'=>array('create')),
array('label'=>'View Issue', 'url'=>array('view', 'id'=>$model->id)),
array('label'=>'Manage Issue', 'url'=>array('admin')),
);
?>
<h1>Update Issue <?php echo $model->id; ?></h1>
<?php echo $this->renderPartial('_form', array('model'=>$model)); ?>
Here is part of my views/issue/_form.php:
<div class="row">
<?php echo $form->labelEx($model,'owner_id'); ?>
<?php echo $form->dropDownList($model,'owner_id',$this->getProject()->getUserOptions()); ?>
<?php echo $form->error($model,'owner_id'); ?>
</div>
<div class="row">
<?php echo $form->labelEx($model,'requester_id'); ?>
<?php echo $form->dropDownList($model,'requester_id',$this->getProject()->getUserOptions()); ?>
<?php echo $form->error($model,'requester_id'); ?>
</div>
Here is my IssueController class:
<?php
