Validations break when file is missing

[chrise86]

For some reason some files that were previously uploaded by a user have disappeared (that's my own issue), but now when updating the model that owns those images (User in this case), I get a 500 error along with:

Dragonfly::Job::Fetch::NotFound <uid> not found

and an extensive error backtrace.

While I could watch and rescue from such errors, the fact that I'm getting a 500 from this doesn't seem right to me.

I guess using if: :image_changed? on the validations would help, but I thought I should mention this anyway.

I am also having this issue - apart from the if: :image_changed? suggestion, has anything bee done about this?

no - Dragonfly only raises an error - it's up to the surrounding application to do what it will with it - in the above case it returns 500.
the other thing to do is to manually wipe the image_uid column, otherwise it's out of sync with the fact that the images don't exist
