EmbedForm with new relation

To insert new attributes to a Product in the default form we just need those few steps:

In the productForm class create the relation with the attribute form.

public function configure() {
    /* Create embedForm with an empty attribute */
    $new_attribute = new ProductAttribute();
    $new_attribute->setProduct($this->object);
    $this->embedForm('new_attribute', new ProductAttributeForm($new_attribute));
    $this->embedRelation('Attributes', new ProductAttributeForm());
}

...and we rewrite the saveEmbeddedForms methods

public function saveEmbeddedForms($con = null, $forms = null) {
    try {
        $new_attribute_form = $this->getEmbeddedForm('new_attribute');
        $values             = $this->getValue('new_attribute');

        /* Validations Rules to save the relation */
        if (empty($values['attribute_id'])) {
            unset($this['new_attribute']);
        }
    } catch (InvalidArgumentException $e) {
        error_log($e->getTraceAsString());
    }
    return parent::saveEmbeddedForms($con, $forms);
}

Oracle extension oci8 in PHP5

Criar pen USB bootable linux em Macosx

Depois de ter a imagem da distro de Linux que pretendemos (no meu caso, Ubuntu), abrimos um terminal e navegamos até ao directório onde está a imagem.

jimmy@machine:~$ cd Downloads/

Executamos agora o comando que converte a imagem de iso para img:

jimmy@machine:~/Downloads$ hdiutil convert -format UDRW -o ubuntu-12.04.3-desktop-i386.img ubuntu-12.04.3-desktop-i386.iso
Reading Master Boot Record (MBR : 0)…
Reading Ubuntu 12.04.3 LTS i386 (Apple_ISO : 1)…
Reading (Windows_NTFS_Hidden : 2)…

Elapsed Time: 21.860s
Speed: 32.3Mbytes/sec
Savings: 0.0%
created: /Users/jimmy/Downloads/ubuntu-12.04.3-desktop-i386.img.dmg

Por omissão, o macosx cria as imagens com .dmg no final, para resolver o problema basta trocar o nome do ficheiro.

jimmy@machine:~/Downloads$ mv ubuntu-12.04.3-desktop-i386.img.dmg ubuntu-12.04.3-desktop-i386.img

Inserimos a drive USB e executamos o seguinte comando para saber onde está a nossa pen, neste caso em (/dev/disk1)

jimmy@machine:~/Downloads$ diskutil list
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *320.1 GB disk0
1: EFI 209.7 MB disk0s1
2: Apple_HFS brain 319.7 GB disk0s2
/dev/disk1
#: TYPE NAME SIZE IDENTIFIER
0: FDisk_partition_scheme *8.0 GB disk1
1: DOS_FAT_32 8.0 GB disk1s1

ATENÇÃO: memorize o numero da drive USB, neste caso é 1 (/dev/disk1)

"Desmontamos" a pen com o comando seguinte:

jimmy@machine:~/Downloads$ diskutil unmountDisk /dev/disk1
Unmount of all volumes on disk1 was successful

E corremos o comando que irá preparar a pen com o SO, troque o 1 (/dev/rdisk1) pelo número identificado no passo anterior:

jimmy@machine:~/Downloads$ dd if=ubuntu-12.04.3-desktop-i386.img of=/dev/rdisk1 bs=1m
