I've read the docs on how to use attachment_fu with activescaffold,
and can't seem to get it working. Specifically, the parent object
(and other parent objects) scaffolding works just fine, but I can't
get the attachment object to store or even to show as a nested link.
The model is : HostedSite has one or more LogoAttachement. Here are
the files:
class HostedSite < ActiveRecord::Base
has_many :logo_attachments
def uploaded_data
nil
end
def uploaded_data=(data)
self.logo_attachments << LogoAttachment.new(:uploaded_data =>
data)
end
end
class Admin::HostedSitesController < Admin::AdminController
active_scaffold :hosted_site do |config|
config.columns =
[:title, :domain, :theme, :uploaded_data, :language, :sbr_sportsbook,
:parent_site, :relative_directory_name ]
list.columns =
[:title, :domain, :sbr_sportsbook, :theme, :parent_site,
:relative_directory_name, :language]
config.columns[:sbr_sportsbook].form_ui = :select
config.columns[:parent_site].form_ui = :select
config.columns[:css_files].options[:rows]=3
config.columns[:javascript_files].options[:rows]=3
config.create.multipart=true
config.nested.add_link("Logos", [:logo_attachments])
end
end
module HostedSiteHelper
def uploaded_data_form_column(record, input_name)
file_field_tag input_name
end
end
class LogoAttachment < ActiveRecord::Base
has_attachment :content_type => :image,
:storage => :file_system,
:resize_to => '290x96>',
:processor => "Rmagick",
:thumbnails => { :small => '73x24>' },
:path_prefix => 'public/uploads/logo_attachments'
validates_as_attachment
belongs_to :hosted_site
end
class Admin::LogoAttachmentsController < Admin::AdminController
active_scaffold :logo_attachment do |config|
config.columns.add :uploaded_data
config.create.multipart=true
config.create.columns = [:uploaded_data]
config.list.columns = [:filename, :image]
end
end
module LogoAttachmentHelper
def image_column(record)
image_tag record.public_filename(:thumb)
end
def uploaded_data_form_column(record, input_name)
file_field_tag input_name
end
end
I've followed the document on the wiki, I think, down to the T and
have tried 10-20 permutations (tried has_one, tried without Admin::
namespace, ...). I can create the attachment in a vanilla controller,
so it appears fine. When I try to list the "Logos" for a
HostedSite, I receive:

Also, if I try to go to the logo listing screen directly and add a
logo, it fails as well.
Thanks in advance...
