I've googled for solutions for this but I can't quite figure out what I'm doing
wrong. (Specifically, this post here seems to indicate that it should work but
it isn't for me
https://groups.google.com/forum/?fromgroups=#!topic/activescaffold/1mWws5a4Yys)
Here's my code
class Product < ActiveRecord::Base
has_many :images, :as => :viewable, :order => :position, :dependent =>
:destroy
end
class Image < Asset
validate :no_attachement_errors
has_attached_file :attachment,
:styles => { :mini => '46x46>',
:small => '181x181>',
:product => '500x500>',
:large => '700x700>',
:at2x => '1000x1000'},
:convert_options => { :all => '-strip' },
:default_style => :product,
:path => "assets/products/:id/:style/:basename.:extension",
:storage => :s3,
:s3_credentials => "#{Rails.root.to_s}/config/s3.yml",
:s3_headers => { 'Cache-Control' => 'max-age=315576000',
'Expires' => 10.years.from_now.httpdate }
end
class Asset < ActiveRecord::Base
belongs_to :viewable, :polymorphic => true
acts_as_list :scope => :viewable
end
class Admin::ProductsController < Admin::ResourceController
active_scaffold :product do |config|
config.actions = [:list, :search, :update, :delete, :create, :nested]
config.update.link.label = "Edit"
config.nested.add_link(:images)
end
end
class Admin::ImagesController < Admin::BaseController
active_scaffold :image do |config|
config.actions = [:list, :search, :update, :delete, :create]
config.update.link.label = "Edit"
end
end
The active scaffold works fine for the Products list page (and create & edit).
When I got to edit the nested Images, however, (using the "Images" link on one
of the rows of products), what I'm getting is a result of all the Images in the
assets table, not restricted to the ones whose viewable_id matches the parent
Product.
I can see the SQL in the log file here:
SELECT `assets`.* FROM `assets` WHERE `assets`.`type` IN ('Image') ORDER BY
`assets`.`id` ASC LIMIT 15 OFFSET 0
This should instead be
SELECT `assets`.* FROM `assets` WHERE `assets`.`type` IN ('Image') AND
viewable_id = '123' AND viewable_type = 'Product' ORDER BY `assets`.`id` ASC
LIMIT 15 OFFSET 0
I also tried adding this to the Admin::ProductsHelper
def options_for_association_conditions(association)
if association.name == :images
{'assets.viewable_id' => @record.id}
else
super
end
end
end
As far as I can tell (using log output and debugging),
options_for_association_conditions is not getting called :(
What have I missed or done wrong? Shouldn't this work?
Thanks,
Jason
