DateTime z MongoDB/Mongoid i poręcze 3 Nie Zapełnianie

Question

Oto kod w moim modelu

include Mongoid::Document 
include Mongoid::Timestamps 

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

Oto kod dla mojej postaci częściowego

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

ale data i czas nigdy nie jest zaludniony . Upewniłem się, że Mongo i Mongoid są również aktualne. Nie jestem pewien, czy czegoś brakuje.

[UPDATE wpisy dziennika]

Answer 1

Mongoid nie obsługuje Wieloparametrowa atrybutów jak data jeszcze, więc trzeba wykonać następujące czynności:

# 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

Najnowsze wersje Mongoid do uchwyt wielu parametrów atrybutów , Po prostu trzeba to moduł w modelu:

include Mongoid::MultiParameterAttributes
