这是我的模型中的代码

include Mongoid::Document
 include Mongoid::Timestamps

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

这是我的表单部分的代码

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

但是日期和时间从未被填充.
我确保Mongo和Mongoid也是最新的.
不知道有没有我错过的东西

解决方法

Mongoid不处理Date的多参数属性,因此您需要执行以下操作：

# 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
