怎么办HABTM管理与Rails的自动补全？

问题描述

我要寻找在Rails的管理与HABTM关联模型的大概典型的问题很好地解决。

I am looking for a good solution for a probably typical problem of managing models with HABTM association in Rails.

假设我们有两个型号 - 产品类：

Let's assume that we have two models -- products and categories:

Products
  has_many :categorizations
  has_many :categories, :through => :categorizations
Categories
  has_many :categorizations
  has_many :products, :through => :categorizations
Categorization
  belongs_to :product
  belongs_to :category

帕特肖内西正在开发从而可以使管理一对一许多（和许多一对多）关联关系：

Pat Shaughnessy is developing modified auto_complete plugin which can allow to manage one-to-many (and many-to-many) association:

有关的人，这将是足够的，但我真的不喜欢这么多的文本字段。我想这是可能的的略有不同的方式使用专利，即使用一个文本字段与自动完成：

For someone that would be enough, but I don't really like so many text fields. I guess it is possible to combine the Ryan Bates' screencasts used by Pat in a slightly different way, namely, using one text field with autocomplete:

此外，它会更好的删除从建议的任务（一到多），或产品清单 |类别（许多到许多）那些已已经添加

Also it would be better to remove from the list of suggested tasks (one-to-many), or products|categories (many-to-many) those which have been already added.

在产品类别的关系的情况下，这样的自动完成将在表格为产品使用这两种，而在形式类别。

In the case of products-categories relationship, such auto completion would be used both in the form for product, and in the form for category.

我希望有对于现有的插件。我不是很在Ruby中有经验，真的不知道如何自己来实现这样的逻辑。

I hope that there is an existing plugin for that. I am not very experienced in Ruby, and don't really know how to implement such logic by myself.

任何帮助AP preciated！
