我有一個has_one配置文件的用戶模型,並且該配置文件屬於該用戶。該配置文件有一個用於單表繼承的type
列,可以是「藝術家」或「偵聽器」。我希望用戶在新用戶視圖中註冊時進行設置。因此,我必須在形式驗證碼:在另一個模型的創建視圖中設置一個模型的屬性
<%= f.fields_for :profile do |t| %>
<div class ="field">
<%= t.label :type, "Are you an artist or listener?" %><br />
<%= t.radio_button :type "artist" %>
<%= t.radio_button :type "listener" %>
</div>
<% end %>
,這在我的用戶模型:
accepts_nested_attributes_for :profile
,但我得到了自己的錯誤:
ArgumentError in Videos#index
Showing /rubyprograms/dreamstill/app/views/videos/_video.html.erb where line #3 raised:
No association found for name `profile'. Has it been defined yet?
這是爲什麼,以及如何能我修復它?
而且我很困惑,爲什麼錯誤在我的視頻部分,沒有提及profile
都帶來了3號線...
UPDATE:
這裏就是整個形式:
<%= form_for(@user) do |f| %>
<% if @user.errors.any? %>
<div id="errorExplanation">
<h2><%= pluralize(@user.errors.count, "error") %> prohibited this user from being saved:</h2>
<ul>
<% @user.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :email %><br />
<%= f.text_field :email %>
</div>
<div class="field">
<%= f.label :password %><br />
<%= f.password_field :password %>
</div>
<div class="field">
<%= f.label :password_confirmation, "Password Confirmation" %><br />
<%= f.password_field :password_confirmation %>
</div>
<%= f.fields_for :profile do |t| %>
<div class ="field">
<%= t.label :type, "Are you an artist or listener?" %><br />
<%= t.radio_button :type "artist" %>
<%= t.radio_button :type "listener" %>
</div>
<% end %>
<div class="field">
<%= f.label :name, "Full Name" %><br />
<%= f.text_field :name %>
</div>
<div class="action">
<%= f.submit %>
</div>
<% end %>
這些都是相關的用戶模型配置文件的三條線:
accepts_nested_attributes_for :profile
before_create :build_profile
has_one :profile

應聲明'HAS_ONE:順便說profile'第一 – fl00r 2011-03-27 21:46:42
