我有一个has_one个人资料的用户模型,该个人资料属于该用户。该配置文件具有type
列,用于单表继承,可以是“artist”或“listener”。我希望用户在新用户视图中注册时设置此项。因此我有以下形式的代码:
<%= 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 %>
这在我的用户模型中:
accepts_nested_attributes_for :profile
但是我得到了他的错误:
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?
为什么会这样,我该如何解决?
此外,我很困惑为什么错误会在我的视频部分中显示第3行,而根本没有提到profile
...
更新:
以下是整个表格:
<%= 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 %>
这些是与用户模型中的配置文件相关的三行:
accepts_nested_attributes_for :profile
before_create :build_profile
has_one :profile
答案 0 :(得分:5)
你应该编辑你的模型并按正确的顺序设置所有这些东西:
has_one :profile # it should be first
accepts_nested_attributes_for :profile
before_create :build_profile
