Rake task imports one line only of txt file - ruby-on-rails

Question

I wrote many simple rake files to import txt files to my mysql.
Everything work perfectly except one model.
I have no errors so I don't know what happening.
The rake imports the first line only. Everything else don't!
The txt is on UTF8 encoding, by the way.
Could be the counter_cache of recipe's associations?
RAILS 3.1
Model:
class Recipe < ActiveRecord::Base
belongs_to :chef, :counter_cache => true
belongs_to :category, :counter_cache => true
belongs_to :cuisine, :counter_cache => true
belongs_to :festivity, :counter_cache => true
belongs_to :daily, :counter_cache => true
after_update :update_counter
# Setup accessible (or protected) attributes for your model
attr_accessible :name,
:slug,
:description,
:ingredients,
:steps,
:...
:status_id,
:created_at,
:updated_at
STATUS = { 'Não publicada' => 0, 'Publicada' => 1, 'Invisível' => 4 }
def status
STATUS.invert[status_id]
end
private
def update_counter
if category_id_changed?
Category.increment_counter(:recipes_count, category_id)
Category.decrement_counter(:recipes_count, category_id_was)
end
if cuisine_id_changed?
Cuisine.increment_counter(:recipes_count, cuisine_id)
Cuisine.decrement_counter(:recipes_count, cuisine_id_was)
end
if festivity_id_changed?
Festivity.increment_counter(:recipes_count, festivity_id)
Festivity.decrement_counter(:recipes_count, festivity_id_was)
end
if daily_id_changed?
Daily.increment_counter(:recipes_count, daily_id)
Daily.decrement_counter(:recipes_count, daily_id_was)
end
end
end
RAKE file:
namespace :db do
desc "import data from files to database"
task :import_recipe => :environment do
puts "Importing Recipe..."
# recipe.txt
File.open("lib/tasks/data/recipe.txt", "r").each do |line|
id, name, slug, description, ingredients, steps, other_tips, cook_time, recipe_yield, diet, light, lactose_intolerance, vegetarian, microwave, video_url, chef_id, category_id, cuisine_id, festivity_id, daily_id, likes_count, rating, ratings_count, views_count, comments_count, status_id, created_at, updated_at = line.strip.split("\t")
d = Recipe.new(
:id => id,
:name => name,
:slug => slug,
:description => description,
:ingredients => ingredients,
:steps => steps,
:...
:status_id => status_id,
:created_at => created_at,
:updated_at => updated_at
)
d.save!
end
puts "=========== > FINISHED!"
