我应该在Symfony2中的哪个位置放置ImageManager类？

Question

I have this MongoDB document: MyBundle/Document/Image .

It represents an image, its path, width, and other attributes.

Now I need to manipulate images, and I think that besides my image manipulation library of choice, I should have an app-specific class to deal with this. I think it would be nice to do something like this:

$image_manager = new ImageManager;
$image = $image_repository->find($id);
$thumbnail = $image_manager->createThumbnail($image);

Now, I'm not sure if I want my ImageManager class to also deal with MongoDB queries, like a custom repository, so let's suppose I don't. Then where should I place my ImageManager class?

Do you think it would be wrong to let it handle both kinds of tasks? (eg: createThumbnail and findAllImagesWithoutThumbnail )

Answer 1

I have the Service folder in my apps at put all the services in there, like:

• UserService
• User\\AvatarService
• OrganizationService
• etc...

You could, of course, use Manager instead of Service , but the idea is the same.

Mostly, my services have methods like:

• find($id)
• save(Class $class)
• delete(Class $class) ,
• etc...

Some services have other methods. For example, User\\AvatarService has the upload() method that handles the uploading of the avatar files.

BTW, I keep my services out of bundles .

I use WideImage in symfony2. I just put it in the vendors and add it to AppKernel.php and autoload. And it's visible project wide.
