Ruby on rails ArticlesController中的ArgumentError#新建

我需要一些帮助。 该应用程序在ruby 1.8.7和rails 3.0.11下运行。 将Rails版本更新到3.1.11后，在新文章页面上出现了一个非常奇怪的错误：

然而，在控制器中，我有：

class ArticlesController < ApplicationController
  def new
    @article = Article.new
  end

编辑2*new.html.erb：

<%= form_for @article do |f| %>
  <%= render "shared/error_messages", :target => @article %>
  <% if admin? %>
    <p>
      <%= f.label :user_id %>
      <%= f.select :user_id,  User.authors_and_admins.collect {|p| [ p.username, p.id ] } %>
    </p>
  <% end %>
  <p>
    <%= f.label :category_id %><%= mark_required(@article, :category_id) %><br/>
    <%= f.select :category_id,  Category.all.collect {|p| [ p.name, p.id ] }, { :include_blank => true } %>
  </p>
  <p>
    <%= f.label :name %><%= mark_required(@article, :name) %><br/>
    <%= f.text_field :name %>
  </p>
  <p>
    <%= f.label :preview %><%= mark_required(@article, :preview) %><br/>
    <%= f.text_area :preview, :size => "70x6" %>
  </p>
  <p>
    <%= f.label :body %><%= mark_required(@article, :body) %><br/>
    <%= f.text_area :body, :class => "mceEditor", :size => "100x20" %>
  </p>
  <% if admin? %>
    <p>
      <%= f.label :publish_on_main %>
      <%= f.check_box :publish_on_main %>
    </p>
  <% end %>
  <%= f.submit %>
<% end %>

Show

Article

model。完整的跟踪也很好。我已经编辑了我的问题。你能在视图中发布你的

form_for

标签的代码吗？用表单视图更新了问题。你能在rails控制台中运行

Acticle.new

并发布完整的跟踪吗？
