schema.rb

Im using paperclip as a nested attribute and trying to upload the photo at the model creation with f.submit

The photos model belongs_to classified model..

c:\Site\brokerv1\brokr>rails --version
Rails 5.0.0


c:\Site\brokerv1\brokr>ruby -v
ruby 2.2.4p230 (2015-12-16 revision 53155) [i386-mingw32]


gem "paperclip", "~> 4.2"

Problem is that after the submission i get a "rollback transaction" from paperclip.

Another weird thing is that i can actually go and see the file saved in the path mentioned by paperclip...

models:

    class Photo < ApplicationRecord

    belongs_to :classified

    has_attached_file :image, :styles => { :large => "600x170", :medium => "250x250!",:thumb => "100x100>" }, :default_url => lambda { |photo| photo.instance.set_default_url}
    validates_attachment_content_type :image, :content_type => ["image/jpg", "image/jpeg", "image/png", "image/gif"]

    validates_attachment_presence :datafile unless :datafile
end


    class Classified < ApplicationRecord
