Paaperclip + couchrest

[Cyrus]

how do I user ?

example:

class Author < CouchRest::ExtendedDocument
use_database COUCHDB_SERVER.default_database

has_attached_file :avatar,
:styles => {
:original => "90x120"
}

end

[viatropos]

class Image < CouchRest::ExtendedDocument
use_database SERVER.default_database
include Paperclip

property :size, :type => "Integer", :default => 1
property :title, :type => "String", :default => ""
property :tags, :type => "Array", :default => []
property :content, :type => "String", :default => ""
property :path, :type => "String"
property :content_type, :type => "String"

# for paperclip
property :attachment_file_name, :type => "String"
property :attachment_content_type, :type => "String"
property :attachment_file_size, :type => "Integer"
property :attachment_updated_at, :type => "Time"

view_by :path
view_by :title
view_by :tags

def initialize(passed_keys={})
super(passed_keys)
self[:title] = self[:attachment_file_name]
self[:content_type] = self[:attachment_content_type]
self[:path] = self.attachment.url
end

# Haven't handled these, or any validations
# set_callback :before_post_process, :before, :check_before
#
set_callback :before_attachment_post_process, :before, :check_before
end

I just made it work with paperclip, haven't tried any of the paperclip
validations so they probably wont work. Tests mostly pass, I still
need to solve a problem with ruby versions (I'm on 1.8.7) and libxml
before everything's going well. But the basics are there.

Goodluck

"Paperclip is intended as an easy file attachment library for
ActiveRecord" is a key.

I got,

I installed the gem http://github.com/viatropos/paperclip as plugin
and modify two lines in vedor/plugins/paperclip/paperclip.rb

behind line 223

#after_save :save_attached_files
#before_destroy :destroy_attached_files

create_callback :after, :save_attached_files
save_callback :after, :save_attached_files
destroy_callback :after, :destroy_attached_files
