Hello,
I have a schema like this:
Image

*id
*exifkey
*name
Metadata
*id
*image_id -> Image

Is there any way for me to create a dictionary-based collection to represent
the image metadata as Metadatakey.name=>Metadata.value ? After a

many thanks for your rich reply.

I'll stay tuned to any sqla development

I can manipulate them through the user session. When I update some

The

Hi chris,
thanks for your reply.
I guess it is not an application framework oriented question. It seems
to me rather a question of database design/access. I have a pointer to

It would be framework oriented, if we were talking
hey yacine, friends,
indeed the problem came partly because i haven't followed the traces of elixir
close enough: i've used backref instead of inverse for manytoone relations.
the only drawback of using inverse, is that it requires the inverse relation to
