DateTime con MongoDB/Mongoid y los carriles 3 No Rellenar

Question

Este es el código en mi modelo

include Mongoid::Document 
include Mongoid::Timestamps 

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

Aquí está el código de mi forma parcial

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

embargo, la fecha y la hora no está poblado . Me aseguré de que Mongo y Mongoid estuvieran actualizados también. No estoy seguro de si hay algo que me falta.

Mongoid no maneja multiparamétrico atributos como la fecha todavía, por lo que hay que hacer lo siguiente:

# 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

Versiones recientes de Mongoid do manejar atributos de parámetros múltiples , Sólo hay que incluir el módulo en su modelo:

include Mongoid::MultiParameterAttributes
