I'm trying to configure Paperclip to provide different missing images based on the instance's category attribute. Every category of the object has its own missing image.
This is my first take:
EDIT to add full models:
class Service < ActiveRecord::Base
attr_accessible :logo, :logo_file_name, :logo_content_type, :logo_file_size, :logo_updated_at
belongs_to :category, :counter_cache => true
has_attached_file :logo,
:path => "/:id-:style-:filename",
:url => ":s3_eu_url",
:default_url => "/logos/:style/#{self.category.name]}.png",
:styles => { :large => "600x400>",
:medium => "300x200>",
:small => "100x75>",
:thumb => "60x42>" }
end
class Category < ActiveRecord::Base
attr_accessible nil
has_many :services
end
In my view, image_tag service.logo.url(:thumb) outputs:
undefined method `category' for #<Class:0x0000010a731620>
Any ideas?
EDIT2:
A working default_url is :default_url => "/logos/:style/missing.png",

See my own answer below.
