Datetime mit MongoDB/Mongoid und Rails 3 Nicht

Question

Bestücken

Hier ist der Code in meinem Modell

include Mongoid::Document 
include Mongoid::Timestamps 

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

Hier ist der Code für meine Form Teil

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

Aber das Datum und die Zeit ist nie bevölkerten . Ich habe sichergestellt, dass Mongo und Mongoid auch auf dem neuesten Stand sind. Ich bin mir nicht sicher, ob mir etwas fehlt.

[UPDATE Log-Einträge]

Answer 1

Mongoid nicht Multi wie Datum umgehen kann noch Attribute, so dass Sie Folgendes tun müssen:

# 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

Aktuelle Versionen von Mongoid do behandeln Multiparameterattribute Sie müssen nur das Modul in Ihrem Modell enthalten:

include Mongoid::MultiParameterAttributes
