i've tried debug manually , wonder whether issue ties in fact @content_type being set nil, although haven't been able deduce further that.

this s3 (or fog, don't have other providers) specific issue , project works fine when using :file storage. thoughts?

this problem bit me. solved putting in config/initializers/carrierwave.rb:

s3_config = yaml.load_file(rails.root.join('config', 'amazon_s3.yml'))[rails.env]  carrierwave.configure |config|   config.storage              = :s3   config.s3_access_policy     = :public_read   config.s3_access_key_id     = s3_config['access_key_id']   config.s3_secret_access_key = s3_config['secret_access_key']   config.s3_bucket            = s3_config['bucket'] end

and putting in config/amazon_s3.yml:

development:   access_key_id: xxxxxxxxxxxxxxxxxxxx   secret_access_key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx   bucket: your-dev-bucket  test:   access_key_id: xxxxxxxxxxxxxxxxxxxx   secret_access_key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx   bucket: your-test-bucket  production:   access_key_id: xxxxxxxxxxxxxxxxxxxx   secret_access_key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx   bucket: your-prod-bucket
