Mongoid embedded photo model not saving [solution]

[elithecho]

Thought this would be helpful to anyone, was facing this issue until I found out what's going on in embedded documents.

When you have Band and Photo model embedded, use cascade_callbacks: true in the embeds_many relation to trigger dragonfly's callback

thanks - does this answer https://github.com/markevans/dragonfly/issues/359?

Seems pretty close.

Without cascade_callbacks, mongoid will not trigger dragonfly's callback so the only field stored is the image_name but not uid.
