Question

提前致谢。试图提供尽可能多的细节。尝试创建更新数据库中布尔记录的链接。基本上，有人可以在没有单独表格的情况下将礼物标记为已购买。我过去做过这一点，发布和删除链接没有问题。：邮件未被控制器接受（仅

我得到：'礼物已成功更新。'单击后消息，但数据库未更新。

<%= link_to "Mark Purchased", user_gift_path(@user, gift, :purchased => true), :method => :put %>

Controller：使用InheritedResources Gem

class GiftsController < InheritedResources::Base
  belongs_to :user

  # redirects to gifts upon update
  def update
    update!{ collection_url }
  end

end

在控制台中工作

>> g=Gift.last
=> #<Gift id: 32, subject: "Birdbath", note: "Saw this at store ", created_at: "2010-01-09 18:52:48", updated_at: "2010-01-09 20:10:24", photo_file_name: "Birdbath.jpg", photo_content_type: "image/jpeg", photo_file_size: 7203, photo_updated_at: "2010-01-09 18:52:48", user_id: 18, store_id: 2, sku: "111390", product_url: "http://www.store.com/birdbath-kyoto-greensto...", price: 130.95, purchased: false, size_color: "blue">
>> g.purchased=true
=> true
>> g.save
=> true
