Hi,
First of all I forgot to mention that I'm using CakePhP 2.0, PHP
5.3.1, and MySQL5.1.41, and Apache 2.2.14.
Some investigation has been done.
So the validation inhereted from the parent model is working. The only
thing I had to do is to no to put the name of the parent model on the
view as I mentioned.
so just simply use:
<?php echo $this->Form->create('ModelB');?>
<fieldset>
<legend><?php echo __('Backadmin Add ModelB'); ?></legend>
<?php
echo $this->Form->input('field1FromA'); // no need to use
ModelA.field1FromA
echo $this->Form->input('field2FromA');
// etc...
echo $this->Form->input('field1FromB');
echo $this->Form->input('field2FromB');
// etc...
?>
</fieldset>
<?php echo $this->Form->end(__('Submit'));?>
This would be pretty cool, but some problem still exist. The form is
based on ModelB, and Form->input(...) function tries to figure out
which type the given field is. This works perfectly for the fields of
the given model but not its parent. It will not see the underlying
table of ModelA so eg. TINYINT(1) is not discovered well and simple
text input is showed instead of a checkbox. But, if I specify the
model in the view the checkbox appears well. (but the validation goes
away...).
I check the dump of the $object retrieved in _introspectModel() in
FormHelper.php which has type eg. ModelB. The validation part of the
dumped array seems ok, contains both rules from the child model and
from the parent model. The problem is that the useTable and table part
contain only the table used by ModelB, models_bs. If I take a closer
look at that object dump (printed by debug($object);) I found
parentClass, and parent. If it does not find the attribute in the
model and in the models joind to it (via habtm), it could look for
them in the model's parent. So this part should be corrected:
if ($key === 'fields') {
if (!isset($this->fieldset[$model]['fields'])) {
$fields =
$this->fieldset[$model]['fields'] = $object->schema();
}
if (empty($field)) { // it's not my case now
foreach ($object->hasAndBelongsToMany
as $alias => $assocData) {
$this->fieldset[$object->alias]['fields'][$alias] = array('type'
=> 'multiple');
}
return
$this->fieldset[$model]['fields'];
} elseif
(isset($this->fieldset[$model]['fields'][$field])) { //
returns here in success
return
$this->fieldset[$model]['fields'][$field];
} else {
// it returns here if the give field is not found, inhereted fields
should be handled from here
return
isset($object->hasAndBelongsToMany[$field]) ? array('type'
=> 'multiple') : null;
}
}
Hope this will help to somebody.
