ruby on rails - Spree module decorator -

-

i'm using spree commerce online shop. want change behaviour during checkout process, defined in app/models/spree/order/checkout.rb inside spree gem. made checkout_decorator.rb @ same point in application.

the problem is, changes aren't loaded. , problem is, inside module inside 1 method, def self.included(klass) method. think have overwrite whole file, instead of 1 method. here decorator looks like:

checkout_decorator.rb

spree::order::checkout.module_eval   def self.included(klass)     klass.class_eval       class_attribute :next_event_transitions       class_attribute :previous_states       class_attribute :checkout_flow       class_attribute :checkout_steps        def self.define_state_machine!          # here want make changes       end        # , other methods include here       # readability, don't show them here     end   end end

the original file checkout.rb spree gem looks this:

module spree   class order < activerecord::base     module checkout       def self.included(klass)         klass.class_eval           class_attribute :next_event_transitions           class_attribute :previous_states           class_attribute :checkout_flow           class_attribute :checkout_steps            def self.checkout_flow(&block)             if block_given?               @checkout_flow = block               define_state_machine!             else               @checkout_flow             end           end            def self.define_state_machine!              # code           end            # , other methods not shown here         end       end     end   end end

so questions are: why not work? module_eval right way this? tried class_eval doesn't work either. how can solve this?

the module_eval method isn't going work you.

you should @ spree checkout flow documentation examples on how customize checkout flow. recommended way customizing checkout flow won't need copy/paste whole bunch of code.

    you need to include Spree::Order::Checkout in order_decorator.rb and use .class_eval

when save object, got below error must non-abstract type public parameterless constructor in order use parameter 't' in generic type or method 'servicestack.redis.redisclient.store<t>(t) redisclass.getinstnace().store(msg); // error here redisclass.getinstnace().save(); as third party's class, can not edit how save object? could create wrapper around third party object call constructor, store wrapper? e.g. public class mywrapper { public thirdpartyobject thirdpartyinstance { get; set; } public mywrapper() { thirdpartyinstance = new thirdpartyobject("constructors"); } }

time series - R growth rate calculation week over week on daily timeseries data -

-
i'm trying calculate w/w growth rates entirely in r. use excel, or preprocess ruby, that's not point. data.frame example date gpv type 1 2013-04-01 12900 office 2 2013-04-02 16232 office 3 2013-04-03 10035 office i want factored 'type' , need wrap date type column weeks. , calculate week on week growth. i think need ddply group week - custom function determines if date in given week or not? then, after that, use diff , find growth b/w weeks divided previous week. then i'll plot week/week growths, or use data.frame export it. this closed had same useful ideas. update: answer ggplot: all same below, use instead of plot ggplot(data.frame(week=seq(length(gr)), gr), aes(x=week,y=gr*100)) + geom_point() + geom_smooth(method='loess') + coord_cartesian(xlim = c(.95, 10.05)) + scale_x_discrete() + ggtitle('week on week growth rate, apr 1') + ylab('growth rate %') (old, correct answer using plot) w...
