How to implement image upload in rails 3 using mongodb

Hi,

Im using mongodb database in my rails 3 app. i tried to implement
image upload using carrier wave gem in my applications but i failed.
Can anyone explain…

Thanks and Regards…

Not quite clear, what ruby gem do You use? MongoMaper, MongoID, other?

I’m using MongoMapper, and it works, here’s my integration of
MongoMapper + CarrierWave (it also works with Paperclip, I used it in
past but don’t like and rewrote with CarrierWave)

https://github.com/alexeypetrushin/mongo_mapper_ext ( go to
spec/carrier_wave/carrier_wave_spec.rb )

For ( kind-of production :slight_smile: ) demo, please go to http://ruby-lang.info -
this site uses MongoMapper and CarrierWave (+ S3) for images (logo,
avatars, …).
