Body
I am new to symfony2. I am using liipImagineBundle to manage image thumbnail. I have a product entity class which uses Lifecycle Callbacks to manage product image. Product.php <pre><code><?php namespace Svipl\AdminBundle\Entity; use Doctrine\ORM\Mapping as ORM; use Gedmo\Mapping\Annotation as GEDMO; use Symfony\Component\HttpFoundation\File\UploadedFile; /** * Svipl\AdminBundle\Entity\Product * @ORM\Entity * @ORM\Table(name="product") * @ORM\Entity(repositoryClass="Svipl\AdminBundle\Entity\ProductRepository") * @ORM\HasLifecycleCallbacks */ class Product{ /** * @ORM\Column(type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @ORM\Column(type="string", length=25, unique=true) */ private $name; /** * @ORM\Column(type="text") */ private $description; /** * @ORM\Column(type="float", length=8) * @var unknown */ private $price; /** * @GEDMO\Timestampable(on="update") * @ORM\Column(name="updated_at", type="datetime") */ private $updated_at; /** * @GEDMO\Timestampable(on="create") * @ORM\Column(name="created_at", type="datetime") */ private $created_at; /** * @ORM\ManyToOne(targetEntity="Category", inversedBy="products") * @ORM\JoinColumn(name="category_id", referencedColumnName="id") */ protected $category; /** * @ORM\Column(name="image", type="string", length=50) */ private $image; public function getAbsolutePath() { return null === $this->image ? null : $this->getUploadRootDir().'/'.$this->image; } public function getWebPath() { return null === $this->image ? null : $this->getUploadDir().'/'.$this->image; } protected function getUploadRootDir() { // the absolute directory path where uploaded // documents should be saved return __DIR__.'/../../../../web/'.$this->getUploadDir(); } protected function getUploadDir() { // get rid of the __DIR__ so it doesn't screw up // when displaying uploaded doc/image in the view. return 'uploads/product'; } private $file; /** * Get file. * * @return UploadedFile */ public function getFile() { return $this->file; } /** * Get id * * @return integer */ public function getId() { return $this->id; } /** * Set name * * @param string $name * @return Product */ public function setName($name) { $this->name = $name; return $this; } /** * Get name * * @return string */ public function getName() { return $this->name; } /** * Set description * * @param string $description * @return Product */ public function setDescription($description) { $this->description = $description; return $this; } /** * Get description * * @return string */ public function getDescription() { return $this->description; } /** * Set price * * @param float $price * @return Product */ public function setPrice($price) { $this->price = $price; return $this; } /** * Get price * * @return float */ public function getPrice() { return $this->price; } /** * Set updated_at * * @param \DateTime $updatedAt * @return Product */ public function setUpdatedAt($updatedAt) { $this->updated_at = $updatedAt; return $this; } /** * Get updated_at * * @return \DateTime */ public function getUpdatedAt() { return $this->updated_at; } /** * Set created_at * * @param \DateTime $createdAt * @return Product */ public function setCreatedAt($createdAt) { $this->created_at = $createdAt; return $this; } /** * Get created_at * * @return \DateTime */ public function getCreatedAt() { return $this->created_at; } /** * Set category * * @param \Svipl\AdminBundle\Entity\Category $category * @return Product */ public function setCategory(\Svipl\AdminBundle\Entity\Category $category = null) { $this->category = $category; return $this; } /** * Get category * * @return \Svipl\AdminBundle\Entity\Category */ public function getCategory() { return $this->category; } /** * Set image * * @param string $image * @return Product */ public function setImage($image) { $this->image = $image; return $this; } /** * Get image * * @return string */ public function getImage() { return $this->image; } private $temp; /** * Sets file. * * @param UploadedFile $file */ public function setFile(UploadedFile $file = null) { $this->file = $file; // check if we have an old image path if (isset($this->image)) { // store the old name to delete after the update $this->temp = $this->image; $this->image = null; } else { $this->image = 'initial'; } } /** * @ORM\PrePersist() * @ORM\PreUpdate() */ public function preUpload() { if (null !== $this->getFile()) { // do whatever you want to generate a unique name $filename = sha1(uniqid(mt_rand(), true)); $this->image = $filename.'.'.$this->getFile()->guessExtension(); } } /** * @ORM\PostPersist() * @ORM\PostUpdate() */ public function upload() { if (null === $this->getFile()) { return; } // if there is an error when moving the file, an exception will // be automatically thrown by move().

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
