Is it possible to use Marshal with wxruby classes to serialize an application''s state? I tried a minimal example of simply serializing a minimal frame object, and I get the error "no marshal_dump is defined for class MinimalFrame". I don''t fully understand this because I also tried another minimal example of dumping a class which did not defined a marshal_dump, and it

Let `User.has_one :profile`. I''ve always thought that `@user.build_profile` is a cheap thing to do - it''s just creating a new object without persisting it. But, in fact, it does 2 queries to the DB: `BEGIN` and `COMMIT`. In my app I have an admin users#index page where users'' details can be edited, and to simplify the code I build a profile whenever it''s

Hi, I have a problem with the marshal_dump and marshal_load... I built two classes XXX, YYY and implemented both methods like this: class YYY @data = "string" @version = 1 def marshal_dump() return [@version,@data] end def marshal_load(var) @version = var[0] case @version when 1 @data = var[1] else

After sending this I realized that this was a Ruby not Rails issue - but the answer may be interesting for those who choose Marshal over Serialize. So, to close this off I don''t know why marshal.dump wasn''t ''dumping'' all attributes, but adding custom marshaling to PDate did the trick. ala, + def marshal_dump + dumped_obj = [date_precision, ajd,

One of my classes uses the class GSL::Poly. It seems from this error message that rails won''t let me store it in the session. ANy ideas what i can do?

Hi all, I''m newbie to ROR, anybody know why I would be getting the following error when I use paginating_find with memcache "no marshal_dump is defined for class StringIO" Im just using the plugin straight out with very default options like from the documentation.

Hallo Zusammen, hatte gestern die Schnauze voll von Vista und habe mir daraufhin Ubuntu installiert. Bin also mit Ubuntu ?berhaupt nicht vertraut. Nun habe ich ohne Erfolg versucht, R zu installieren. Soweit ich der Anleitung folgen konnte habe ich es so wie auf http://wiki.ubuntuusers.de/R gemacht. Im Terminal kann ich R problemlos starten. Allerdings bei der Installation von

hi all, in the course of my hacking i wanted to marshal mechanized objects (whether the agent, page, or other). this may be a rather particular use-case, but i figured i would report. marshalling does not work on certain objects, in particular IO objects, and since mechanized uses Net::HTTP it makes use of IO objects. so it turns out that it you just do a = WWW::Mechanize.new page = a.get

I have a problem with the :include option in find for my has_one :through association. I have Users, Profiles and Customers, all connected to each other with a has_one :through => :membership association like this: class Profile < ActiveRecord::Base #could also be user or customer has_one :membership # i saw an acrticle of Ryan about has_one :through, there this would be has_many, is

I know that this was a topic in March at DSC, but I was suffering from a nasty migraine that prevented me from paying as much attention as I ought to. What's the current state-of-the-art regarding packaging/serialization of R objects? Or is it still vaporish (i.e. nothing built)? I'm a bit more interested in functions/closures than "ordinary data". best, -tony -- A.J.

I have an item which has a hash for one of its fields. When i store it in the db, i want to do a Marshal.dump of the hash, and similarly, do a Marshal.load to turn the saved blob back into a hash again. Is there a way to easily write this into the model, so that it happens automatically when saving and loading a record? thanks max -- Posted via http://www.ruby-forum.com/.

Hello,   I am trying to write some code that dumps R objects to the harddisk in a binary format so they can be quickly re-used later. Goal is to save time. The objects may be quite large (e.g. classes for a GUI). I was thinking that save() and load() would be suitable for this (until now I only thought it could be used for 'real' data, e.g. matrices, data.frames etc), but I am hoping any
