Acts-as-Taggable-顯示散列對象而不是標籤名稱

Acts-as-Taggable-on無法正確輸出名稱列，也不能正確顯示對象本身的信息的整個散列。如何設置顯示頁面以分別爲模型打印每個標籤？我到目前爲止的代碼如下。Acts-as-Taggable-顯示散列對象而不是標籤名稱

show.html.erb

<%= @user.user_profile.tags.each do |tag| %> 
<%= tag.name %> 
<% end %>

結果顯示頁

#<ActsAsTaggableOn::Tag::ActiveRecord_Associations_CollectionProxy:0x2b7534d0> games [#<ActsAsTaggableOn::Tag id: 1, name: "games", created_at: "2017-08-25 15:54:30", updated_at: "2017-08-25 15:54:30", taggings_count: 1>] 1

控制檯輸出

    ActsAsTaggableOn::Tag Load (25.0ms) 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 = 'tags' AND taggings.tagger_id IS NULL) [["taggable_id", 2], ["taggable_type", "UserProfile"]]

user_profile.rb

class UserProfile < ApplicationRecord 
    acts_as_taggable 
    acts_as_taggable_on :abilities

我一定累洛爾（在第一行中的 '<％' 之後沒有 '='）嘗試

<% @user.user_profile.tags.each do |tag| %> <%= tag.name %> <% end %>

。謝謝，這正是我需要做的。 –
