Hi all, I am writing a simple shopping cart which will consist of a single class. There will be no DB table for carts so I do not want to make my Cart a model. But where do I place my Cart class so that I can access it in my controllers? I want to be able do do things like this (for instance in a shop controller): def add_to_cart @session[''cart''].add(article_id, amount)

Hi all, I just updated lighttpd from 1.4.8 to 1.4.9 and it now refuses to start with the following error: 2006-01-24 23:12:24: (mod_fastcgi.c.989) execve failed for: public/ dispatch.fcgi No such file or directory 2006-01-24 23:12:24: (mod_fastcgi.c.1015) the fastcgi-backend public/ dispatch.fcgi failed to start: 2006-01-24 23:12:24: (mod_fastcgi.c.1019) child exited with status 2

Hi all, I would like to write some custom helpers like the ones available as form helpers text_field, text_area and the like. My first try was this: custom_helper(obj, meth) ''some_string'' + obj.send(meth) + ''some_other_string'' end Object and method are being passed as symbols like this: custom_helper(:person, :name) and Ruby rightfully complains that

Hi all, I have a mutilingual app and want to customize the validation error messasges. I cannot override them as I need them in more than one language, so I have done the following: validates_presence_of :some_attr, :message => _(''should not be blank'') I am using gettext to translate the message. This works in development mode, but not in production, even after a

Hi all, is there a way to override the validation methods so as to avoid the div.fieldWithErrors divs from being created on the redisplayed form? Many thanks in advance, Nicky

Dear Railers, I am toying with a new project and have a schema design question. I have a tree-like node structure. Each of the nodes will be associated with a single object. This associated object can be of a variety of types. I represent the tree through a Node class which acts_as_tree. Now imagine three other classes--Animals, Fruits and Vegetables. Each node will have an association

The only call that PeriodicalUpdater will make periodically to you is the insertion call. I think of onComplete as being ''I''ve done everything I was going to do'', which for Updater is right after it''s done a single update, but for PeriodicalUpdater, it''s after it''s finished all of its updates, so you''ll only get it once for any call

>From a quick look at the source code, it looks like onComplete is only called when the whole thing is done - in the case of Updater, right after the update, in the case of PeriodicalUpdater, right after it has been stopped. It looks like you need to pass your callback method as an ''insertion'' method in the options. This takes two parameters, the first will probably be the

Hi, I have created a plot using filled.contour() and have the problem that one of the axis titles and an axis label are overlapping. I have tried changing par()$mgp (with, e.g. par(mgp=c(4,1,0)) ), but this just makes the title go off the screen. I can't work out how to make the plot take up less space in the window, so I can hopefully change mgp and sort the problem. Is changing mgp the only

Dear R experts, Is it true that R generally cannot handle medium sized data sets(a couple of hundreds of thousands observations) and threrefore large date set(couple of millions of observations)?

Hey, fellow LART controlllers, I''d like to ask if someome has a real esfq experience with HTB class hierarchy and esfq qdiscs. Lets say that I want to unite the connections to 10 client PCs with u32 or fw filters (doesn''t matter which one in fact) into one HTB class with esfq qdisc at the end. Did anyone tried it, and more important, did it worked the way it is supposed to? As

Hi all, I noticed that my sessions and flashes are not working in IE6 (no problem with safari or firefox). I did a <%= debug session %> and indeed IE6 is showing session[:new_session] to be true all the time. This means a new session is created for every request. An old version of the same application is running on the same server under a different subdomain. In this sessions are

Hi, This may be a stupid question, but how are the "std. error" values returned by lm() calculated? For example > summary(lm) Call: lm(formula = log10(moments[2, 1:10]) ~ log10(L_vals[1:10])) Residuals: Min 1Q Median 3Q Max -0.0052534 -0.0019473 0.0006785 0.0011740 0.0059541 Coefficients: Estimate Std.

Hello, I have table called ''listings.'' There are a certain combination of properties which make a listing viewable (e.g., it is confirmed, has been authorized, hasn''t expired, etc.). Each listing has one and only one category. I want to be able to do things like Listing.find_viewable(...) and Category.find(...).viewable_listings, but I see no way to do this
