ここに私のモデルのコードがあります

 include Mongoid::Document
 include Mongoid::Timestamps

 field :message, :type => String
 field :send_at, :type => DateTime

ここに私のフォーム部分のコードがあります

 <%= f.label :send_at %><br />
 <%= f.datetime_select :send_at %>

ただし、日付と時刻は入力されません。Mongo と Mongoid も最新であることを確認しました。私が見逃しているものがあるかどうかはわかりません。

最近のバージョンの Mongoidはマルチパラメーター属性を処理します。モデルにモジュールを含めるだけです。

include Mongoid::MultiParameterAttributes

Mongoid は Date のようなマルチパラメータ属性をまだ処理していないため、次のことを行う必要があります。

# copied from: https://gist.github.com/315227
# add this to a new file in your lib directory
module MultiParameterAttributes
  def filter_time(attributes, name)
     attrs = attributes.collect do |key, value|
       if key =~ /^#{Regexp.escape(name.to_s)}\((\d+)(\w)\)$/
         [$1.to_i, value.send("to_#$2")]
       end
     end.compact.sort_by(&:first).map(&:last)
     Time.zone.local(*attrs) unless attrs.empty?
  end
end

# include the module above in your application_controller.rb
class ApplicationController < ActionController::Base
  include MultiParameterAttributes
end

# and in the controller action where you process the form params, use filter_time
class YourController < ApplicationController
  def your_action
    time = filter_time(params, :my_time_attribute_name)
  end
end
