ActsAsTagtableOn:标签未在数据库中持久化

Question

我正在使用acts_as_tagtable_on（3.4）插件来标记Rails（4.2.4）。我尝试通过种子文件和控制台添加自定义标记，虽然它似乎添加了属性，但我无法访问它们。

我的型号：

class Recipe < ActiveRecord::Base
  acts_as_taggable_on :tags
  acts_as_taggable_on :dietaries, :meals, :cuisines, :sources
end

种子文件：

tarte = Recipe.create(title: "Caramelized Tomato Tarte Tatin", url: "www.chocolateandzucchini.com", notes: "Lorem ipsum", favorite: false)
tarte.dietary_list.add("vegetarian," "vegan")
tarte.meal_list.add("appetizers", "mains", "dinner")
tarte.cuisine_list.add("French")
tarte.source_list.add("Chocolate and Zucchini")

控制台步骤（在运行种子以在上面的种子文件中创建配方之后）：

tarte = Recipe.first
tarte.dietary_list.add("vegetarian," "vegan")
tarte.meal_list.add("appetizers", "mains", "dinner")
tarte.cuisine_list.add("French")
tarte.source_list.add("Chocolate and Zucchini")

当我调用Recipe.first.dietary_list时，它会运行一个查询

Recipe Load (0.6ms)  SELECT  "recipes".* FROM "recipes"  ORDER BY "recipes"."id" ASC LIMIT 1
ActsAsTaggableOn::Tag Load (0.7ms)SELECT "tags".* FROM "tags" INNER JOIN "taggings" ON "tags"."id" = "taggings"."tag_id" WHERE "taggings"."taggable_id" = $1 AND "taggings"."taggable_type" = $2 AND (taggings.context = 'dietaries' AND taggings.tagger_id IS NULL)  [["taggable_id", 1], ["taggable_type", "Recipe"]]

但它返回一个空数组：

=> []

如果我调用Recipe.first.dietaries，它会返回一个空的集合代理：

Recipe Load (0.6ms)  SELECT  "recipes".* FROM "recipes"  ORDER BY "recipes"."id" ASC LIMIT 1
ActsAsTaggableOn::Tag Load (0.5ms)  SELECT "tags".* FROM "tags" INNER JOIN "taggings" ON "tags"."id" = "taggings"."tag_id" WHERE "taggings"."taggable_id" = $1 AND "taggings"."taggable_type" = $2 AND "taggings"."context" = $3  [["taggable_id", 1], ["taggable_type", "Recipe"], ["context", "dietaries"]]
=> #<ActiveRecord::Associations::CollectionProxy []>

使用这个工具有什么我遗漏的吗？或者，有更好的标记工具吗？
