Я использую Paperclip с Rails для сохранения вложений. Мне нужно что-то сделать после сохранения вложения. Проблема заключается в том, что after_photo_post_process (так же как after_post_process) вызывается до того, как вложение действительно изменяется и сохраняется.
Вот код:
after_photo_post_process :update_facebook
#after_create :update_facebook
def update_facebook
puts "UPDATE_FACEBOOK"
puts item_id.to_s
if(!@graph)
@graph = Koala::Facebook::GraphAPI.new(User.find(Item.find(item_id).user_id).fbprofile.access_token)
end
options = {
:message => "I've just added " + Item.find(item_id).title + " to my 111 items list. Check it out: http://111items.com/items/" + item_id.to_s,
:picture => "http://localhost:3000" + photo.url(:small),
:link => "http://111items.com/items/" + item_id.to_s
}
puts options
@graph.put_object("me", "feed", options)
end
А вот вывод сервера:
UPDATE_FACEBOOK
157

Интересно, почему это происходит?
Обновление: использование Rails.logger дает этот вывод с сервера:
{:message=>"I've just added Another one to my 111 items list. Check it out: http://111items.com/items/165", :picture=>"http://111items.com/images/rails.png", :link=>"http://111items.com/items/165"}

Итак, after_photo_post_process по-прежнему вызывается до того, как вложение действительно сохраняется.
