我已经为此工作了几天，到处搜索让我以某种方式接近我的目标。

我正在尝试在我的应用程序中上传多个图像。

电影.rb

class Movie < ActiveRecord::Base
  attr_accessible :title, :notes, :link, :screenshots_attributes
  has_many :comments, :as => :commentable
  has_many :screenshots
  accepts_nested_attributes_for :screenshots, allow_destroy: true
  belongs_to :cast
end

截图.rb

class Screenshot < ActiveRecord::Base
  attr_accessible :image, :movie_id
  belongs_to :movie
  mount_uploader :image, ImageUploader
end

电影控制器.rb

  def create
    @movie = Movie.new(params[:movie])
    @cast = Cast.find(params[:cast_id])
    if @release.save
      redirect_to cast_movie_path(params[:cast_id], @movie), notice: "#{t 'movie.created'}"
    else
      render action: "new"
    end
  end

_form.html.rb（电影）

  <%= form_for [@cast, @movie], :id => 'fileupload' do |f| %>
    <%= f.text_field :movie %></div><%= t 'movie.title' %><br />

    <%= f.fields_for :screenshots do |s| %>
      <%= s.file_field :image, multiple: true %><%= t 'movie.screenshots' %><br />
    <% end %>

    <%= f.text_area :notes %></div><%= t 'movie.notes' %></div><br />

    <div class="actions">
    <%= f.submit "#{ t 'general.submit'}", :class => "btn"%>
    </div>
  <% end %>

当我提交表单时，只有一个图像被上传，尽管当我“提高 params.to_yaml”（用于调试目的）时，我得到 NoMethodError

undefined method `name' for nil:NilClass

和请求参数http://pastebin.com/4iZ​​vtnED
