ruby on rails - carrierwave deletes user avatar on user profile update -

user creates profile , upload avatar.... that's ok. user decide add together more info visit profile settings sec time , alter 1 or 2 text fields no avatar. after saving changes avatar disappears. want remain there if not changed.

validations, parameters disallow if avatar not selected, nil seems help.

edit: adding code

blog.rb model:

mount_uploader :blog_title_img, blogtitleuploader

blog_title_uploader.rb:

ok future visitors similar problem found solution:

in blog_title_uploader.rb change:

def filename "#{secure_token()}.jpg" end

to:

def filename "#{secure_token()}.jpg" if original_filename.present? end

now page behaves desired. should seek console output , analyze doing under hood sooner...

solution taken here: carrierwave filename keeps changing on update_attributes
