篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了CakePHP-合并添加和编辑问题相关的知识,希望对你有一定的参考价值。
可以这么说,我正在尝试将添加和编辑功能“合并”到一个“保存”功能中,无论是否提供了模型的$ id,该功能都会更新或添加模型的新实例。通过开始编写此代码,我意识到这个想法比Cakephp的添加和编辑方法内置的方法带来更多的麻烦,实际上,我的导师坚持认为我将其合并,因此即使我个人认为这不是最佳方法,也应尝试一下。
ItemTypesController.php
class ItemTypesController extends AppController {
public function save($id = null) {
if($this->request->is(array('post', 'put'))){
$this->ItemType->set($this->request->data);
//if i put an exit() funct here, it exits on this spot
if($this->ItemType->validates()){
if(!$id){
$this->ItemType->create();
if ($this->ItemType->save($this->request->data)) {
$this->Flash->success(__('The item type has been saved.'));
return $this->redirect(array('action' => 'index'));
} else {
$this->Flash->error(__('The item type could not be saved. Please, try again.'));
}
}
else{
if ($this->ItemType->save($this->request->data)) {
$this->Flash->success(__('The item type has been saved.'));
return $this->redirect(array('action' => 'index'));
} else {
$this->Flash->error(__('The item type could not be saved. Please, try again.'));
}
}
} else {
$this->Flash->warning($this->ItemType->validationErrors, array(
'key' => 'negative'
));
}
} else {
$options = array('conditions' => array('ItemType.' . $this->ItemType->primaryKey => $id));
$this->request->data = $this->ItemType->find('first', $options);
}
$this->set('classes', $this->ItemType->classes);
}
}
因此,如果没有提供$ id,则该函数将进入if block,如果我输入一个新ItemType的链接,就是这种情况。而且它对于create很有效,但是,当我尝试对其进行更新时,由于“ isUnique”规则,它始终要求必须更改任何字段,因此我将该规则设置为仅用于create,但是CakePHP会自动考虑其create函数。 ,虽然这里使用了我的save()函数,但它可能认为它需要为我的函数输入该规则。
ItemType.php
class ItemType extends AppModel {
public $classes = array(
'product' => 'Proizvod',
'kit' => 'Kit (bundle)'
);
public $validate = array(
'code' => array(
'required' => array(
'rule' => 'notBlank',
'message' => 'A code is required'
),
'alphanum' => array(
'rule' => 'alphanumeric',
'message' => 'A code must be an alphanumeric value'
),
'unique' => array(
'rule' => 'isUnique',
'message' => 'This code already exists!',
'required' => 'create'
),
'between' => array(
'rule' => array('lengthBetween', 3, 7),
'message' => 'Code must be between 3 and 7 characters long'
)
),
'name' => array(
'required' => array(
'rule' => 'notBlank',
'message' => 'A name is required'
),
'unique' => array(
'rule' => 'isUnique',
'message' => 'This name already exists!',
'required' => 'create'
),
'between' => array(
'rule' => array('lengthBetween', 3, 30),
'message' => 'Name must be between 3 and 30 characters long'
)
),
'class' => array(
'valid' => array(
'rule' => array('inList', array('product', 'material', 'kit', 'semi_product', 'service_product', 'service_supplier','consumable','inventory','goods','other')),
'message' => 'Please enter a valid class',
'allowEmpty' => false
)
),
'tangible' => array(
'bool' => array(
'rule' => 'boolean',
'message' => 'Incorrect value for the checkbox'
)
),
'active' => array(
'bool' => array(
'rule' => 'boolean',
'message' => 'Incorrect value for the checkbox'
)
)
);
public $hasMany = array(
'Item' => array(
'className' => 'Item',
'foreignKey' => 'item_type_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
}
这是我要输入新视图或更新视图的视图:
index.ctp
<div class="itemTypes index">
<h2><?php echo __('Item Types'); ?></h2>
<table cellpadding="0" cellspacing="0">
<thead>
<tr>
<th><?php echo $this->Paginator->sort('id'); ?></th>
<th><?php echo $this->Paginator->sort('code'); ?></th>
<th><?php echo $this->Paginator->sort('name'); ?></th>
<th><?php echo $this->Paginator->sort('class'); ?></th>
<th><?php echo $this->Paginator->sort('tangible'); ?></th>
<th><?php echo $this->Paginator->sort('active'); ?></th>
<th><?php echo $this->Paginator->sort('created'); ?></th>
<th><?php echo $this->Paginator->sort('modified'); ?></th>
<th class="actions"><?php echo __('Actions'); ?></th>
</tr>
</thead>
<tbody>
<?php foreach ($itemTypes as $itemType): ?>
<tr>
<td><?php echo h($itemType['ItemType']['id']); ?> </td>
<td><?php echo h($itemType['ItemType']['code']); ?> </td>
<td><?php echo h($itemType['ItemType']['name']); ?> </td>
<td><?php echo h($itemType['ItemType']['class']); ?> </td>
<td><?php if($itemType['ItemType']['tangible']) echo "Yes"; else echo "No" ?></td>
<td><?php if($itemType['ItemType']['active']) echo "Yes"; else echo "No" ?></td>
<td><?php echo h($itemType['ItemType']['created']); ?> </td>
<td><?php echo h($itemType['ItemType']['modified']); ?> </td>
<td class="actions">
<?php echo $this->html->link(__('View'), array('action' => 'view', $itemType['ItemType']['id'])); ?>
<?php echo $this->Html->link(__('Edit'), array('action' => 'save', $itemType['ItemType']['id'])); ?>
<?php echo $this->Form->postLink(__('Delete'), array('action' => 'delete', $itemType['ItemType']['id']), array('confirm' => __('Are you sure you want to delete # %s?', $itemType['ItemType']['id']))); ?>
</td>
</tr>
<?php endforeach; ?>
</tbody>
</table>
<p>
<?php
echo $this->Paginator->counter(array(
'format' => __('Page {:page} of {:pages}, showing {:current} records out of {:count} total, starting on record {:start}, ending on {:end}')
));
?> </p>
<div class="paging">
<?php
echo $this->Paginator->prev('< ' . __('previous'), array(), null, array('class' => 'prev disabled'));
echo $this->Paginator->numbers(array('separator' => ''));
echo $this->Paginator->next(__('next') . ' >', array(), null, array('class' => 'next disabled'));
?>
</div>
</div>
<div class="actions">
<h3><?php echo __('Actions'); ?></h3>
<ul><li><?php echo $this->Html->link(__('New Item Type'), array('action' => 'save')); ?>
</li>
</ul>
</div>
save.ctp
<div class="itemTypes form">
<?php echo $this->Form->create('ItemType'); ?>
<fieldset>
<legend><?php echo __('Add Item Type'); ?></legend>
<?php
echo $this->Form->input('code');
echo $this->Form->input('name');
echo $this->Form->input('class', array('options' => $classes));
echo $this->Form->input('tangible');
echo $this->Form->input('active');
?>
</fieldset>
<?php echo $this->Form->end(__('Submit')); ?>
</div>
<div class="actions"><h3><?php echo __('Actions'); ?></h3><ul><li><?php echo $this->Html->link(__('List Item Types'), array('action' => 'index')); ?></li></ul></div>
答案
功能保存的编码不好,因为从未设置过模型的ID,所以它不知道它是否正在更新。
public function save($id = null) {
if($this->request->is(array('post', 'put'))){
if($id){
$this->request->data['ItemType']['id'] = $id;
}
$this->ItemType->set($this->request->data);
if($this->ItemType->validates()){
if(!$id){
$this->ItemType->create();
}
if ($this->ItemType->save($this->request->data)) {
$this->Flash->success(__('The item type has been saved.'));
return $this->redirect(array('action' => 'index'));
} else {
$this->Flash->error(__('The item type could not be saved. Please, try again.'));
}
} else {
$this->Flash->warning($this->ItemType->validationErrors, array(
'key' => 'negative'
));
}
} else {
$options = array('conditions' => array('ItemType.' . $this->ItemType->primaryKey => $id));
$this->request->data = $this->ItemType->find('first', $options);
}
$this->set('classes', $this->ItemType->classes);}
现在,这是函数的外观。
