Question

自Rails 3.2更新以来，我遇到了一个奇怪的问题。

我有两个模型：

class User < ActiveRecord::Base
  has_many :educations
  accepts_nested_attributes_for :educations, :reject_if => lambda {|c| c[:school_name].blank?}, :allow_destroy => true
  ...
end

class Education < ActiveRecord::Base
  belongs_to :user
  ...
end

在数据库中：

create_table :educations do |t|
  t.integer :user_id
  t.integer :school_id
  t.date :start
  t.date :end
  t.string :concentration
  t.timestamps
end

在表格中，我有这个：

= date_select('user[educations_attributes]', "start", :index => "index", :discard_day => :true, :start_year => 1950, :include_blank => true, :class => 'mini')

当我发送带有PUT的表格时，参数是这样的：

Started PUT "/users/1" for 127.0.0.1 at 2012-01-26 10:03:35 +0100
Processing by UsersController#update as XML
  Parameters: {"user"=>{"educations_attributes"=>{ "1327568594259"=>{"school_name"=>"Test", "concentration"=>"Test concentration", "start(3i)"=>"", "start(2i)"=>"10", "start(1i)"=>"2003", "end(3i)"=>"", "end(2i)"=>"12", "end(1i)"=>"2010", "_destroy"=>""}}}

数据库插入是这样的：

  [1m[35mSQL (0.3ms)[0m  INSERT INTO `educations` (`concentration`, `created_at`, `end`, `school_id`, `start`, `updated_at`, `user_id`) VALUES ('Test concentration', '2012-01-26 09:03:35', NULL, 14, NULL, '2012-01-26 09:03:35', 1)

任何人都知道这是为什么？参数中的索引似乎是正确的。

非常感谢你！

表单中的日期属性，不保存在数据库中，但可用作参数
