How to display default image if image does not exist on aws s3 ?

[vishalmelmatti]

Hi,

I am using LiipImagineBundle with KnpGaufretteBundle, I can load images from aws s3 but if image does not exist it displays blank, I want to display my default image.

I couldn't find any configuration for this.

Can such configuration be made available in this bundle by any chance ? or is invalid feature request ?

Thanks.

the feature request make sense IMO. Not sure about the right implementation. Should we hard code it in the config, of loader for example or pass it as a parameter of twig function?

I tried to dig in to code, NotFound exception thrown by AWS S3 SDK getObject API is propogated till ImaginController:filter action but it is not handled in CacheManager:generateUrl . May be the call to
$this->router->generate
should be put in try cache and in case of exception we should call it again with

    $params = array(
        'path' => ltrim('%path_to_default_image%', '/'),
        'filter' => $filter
    );

or may be in ImagineController itself.

We should let path_to_default_image parameter be defined in config to be set by user.

Still makes sense to do, need to investigate the right way to do it and write a more clear descriptive issue.
