post.rb

class Post < ActiveRecord::Base


    validates :company, :contact, :email, :telephone, :website, presence: true
    belongs_to :posts

    :storage => :dropbox,
    :dropbox_credentials => Rails.root.join("config/dropbox.yml"),
end

getting syntax errors in this file so have removed commas but still get same errors

Answer 1

Have you tried using the has_attached_file attribute of Paperclip (as described in the paperclip-dropbox gem docs):

#app/models/post.rb
Class Post < ActiveRecord::Base
    has_attached_file :avatar,
    :storage => :dropbox,
    :dropbox_credentials => Rails.root.join("config/dropbox.yml")
end
