У меня есть водяные знаки, галереи и фотографии моделей.
Галерея belongs_to
Водяной знак
Фото belongs_to
Галерея
class Photo < ActiveRecord::Base
before_save :save_dimensions, :set_orientation
belongs_to :gallery
has_attached_file :image,
:processors => [:watermark],
:styles => {
:thumbnail => ["80x80>"],
:small => {
:geometry => "200x200>",
:watermark_path => "#{gallery.watermark.image.path(:small)}",
:position => "Center"
},
:medium => {
:geometry => "400x400>",
:watermark_path => "#{gallery.watermark.image.path(:medium)}",
:position => "Center"
},
:large => {
:geometry => "600x600>",
:watermark_path => "#{gallery.watermark.image.path(:large)}",
:position => "Center"
}
},
:path => ":rails_root/public/images/galleries/:gallery_id/:id/:style_:basename.:extension",
:url => "galleries/:gallery_id/:id/:style_:basename.:extension"
validates_attachment_presence :image
validates_attachment_content_type :image, :content_type => ['image/jpeg', 'image/png']
attr_protected :image_file_name, :image_content_type, :image_file_size
end
С этим я получаю undefined local variable or method 'gallery'
. Если я попробую вот так с :gallery_watermark_path
, определенным с использованием Paperclip.interpolations, то молча произойдет сбой.
:watermark_path => ":gallery_watermark_path"
Paperclip не обрабатывает :gallery_watermark_path
:

Короче говоря, как передать переменную водяного знака в процессор?
