similar to: Override Validation?

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, if I have a has_many and belongs_to relations like this category has many articles article belongs to category is there a way I can specify the order of articles when pulling them up with @some_category.articles ? Many thanks in advance! -- Nicky

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

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

Hi! If i have an object it''s easy. But i''m making a simple contact form and i check if email address is correct. If it''s not i redisplay the form with the info that there was an error (should i use redirect_to or render :action? what''s the difference?), but all previously submitted data is lost. I tried creating variables using names of the form fields, but

I have a rather complex object with a number of attributes. For a variety of reasons, I would like one view to create the object with only a couple of fields completed, then a second and third view to finish all the fields. I would like the model to validate_presence_of all these fields, since eventually I need them all there, and I would like each page to validate its portion of the fields that

I have a weird problem going on. All of sudden, records for a certain model will not save with #save Please take a look at this: >> p = Payment.new(:payment_reason_id => 1, :payment_method_id => 1, :date => Date.today, :amount => ''5.00'', :payable => Student.find(608)) => #<Payment id: nil, school_id: nil, payment_reason_id: 1, payment_method_id: 1,

Does anyone know how to override the <div class="fieldWithErrors"> behaviour when a form field is incorrect? Thanks, Dan

Hi! The topic can be a bit misleading, because it may suggest that i want to change css style. What i''d like to change is that normally, when there''s an error, rails creates a div element with the fieldWithErrors class as the parent of the input. I''d like to change this behavior, so the input element itself will have this class added to its current classes and

I have a bit of code in a controller that looks like this: @current_festival.monitor_preferences.each do |pref| if pref.user_id == @me.id pref.preference = params[:monitor_pref] #pref.save end end @current_festival.save_with_validation(false) the Festival class has_many :monitor_preferences the MonitorPreference class belongs_to :festival In the configuration above, the

I want to build a simple calculator with 1 form and a results page. The form will be redisplayed with an error message upon an invalid value entered. I won''t be using any database/active record for this. The problem i have is when i return to the form page i want to redisplay the values already entered in the form fields. Should i use text_field (which seems to be tied to a model) or

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

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)? I googled and I found lots of questions regarding this issue, but curiously there were no straightforward answers what can be done to make R capable of handling data. Is there sth inherent in the

this is kinda trivial but I''m anal and it bugs me :) whenever there''s a error in the form the error field is wrapped with <div class="fieldWithErrors"> </div> this throws my form''s styling off because it puts too much space b/t fields and worse makes the form as wide as possible. How do I fix this? I''ve tried div.fieldWithErrors {

I''ve run across something that I''m not sure how to fix. This is with MSIE, Firefox doesn''t seem to have the same problem. When rails displays form fields in error using the css element fieldWithErrors, and the form field is enclosed in a table data tag, the entire background of the table data element is set to red instead of just the border of the form element.

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

>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
