Ruby on rails 参数数目错误（2代表1）Rails表单_代表

更新 当我将@video更改为我拥有的任何其他型号时，它不会出错。（它显然无法正常工作，因为我需要将其连接到视频）。这可能是什么原因造成的

form\u for

自动为您提供多部分true。试着摆脱它

---

通过以下修改进行检查：

app/views/shared/_form.html.erb:1:in `_app_views_shared__form_html_erb___611020419_98374470'
app/views/videos/translate_video_handwritten.html.haml:54:in `_app_views_videos_translate_video_handwritten_html_haml__702424599_100568110'

{:multipart=>true}）do | f |%>

{:multipart=>true}do | f |%>

视频是一种资源吗？还有，你们有视频线路吗？ 如果是，请尝试在模型中注释carrierwave代码。

---

如果不起作用，可以粘贴完整的应用程序跟踪吗？

尝试使用

url

作为参数。喜欢

我希望能有所帮助。

您可能有一个gem/库覆盖了

表单的默认行为。你能发布你的Gemfile吗？常见的罪魁祸首是元搜索和客户端验证否，我只是把用户作为一种资源，与他们相关的路由有时包括视频。在我的应用程序中，视频被分配给用户。这可能是问题所在吗？
require 'carrierwave/orm/activerecord'

class Video < ActiveRecord::Base
  attr_accessible :course, :qa_complete, :qa_id, :subject, :title, 
  :translate_complete, :translator_id, :type_complete, :typer_id, :video_id, :due_date, :translation_handwritten

  validates :video_id, :presence => true, :uniqueness => true #add uniqueness in db too

  mount_uploader :translation_handwritten, TranslationsUploader


end

app/views/shared/_form.html.erb:1:in `_app_views_shared__form_html_erb___611020419_98374470'

<%= form_for( @video, :html => {:multipart => true}) do |f| %>
