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, 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

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

Hello, people! I have a problem. I googled, asked for help on IRC. I can''t find an answer. Suppose I have model Cart (from "Agile Web Development with Rails"). I added call to logger.warn("Some warning") to one of it''s methods. It fails with NameError, because ''logger'' is unknown to model. undefined local variable or method

Hi all, I''m having trouble figuring out how to handle stock levels in a new store I''m building. When products are entered into the admin of the store, they have a stock number associated with them. What I''m not sure about, is how I go about maintaining this stock level. Take this scenario: 1. User A adds an item to their cart, and I check that it''s in stock -

Given this code (which renders rjs), I''m faced with the fixture- driven way of spec-ing or mocking. How the heck to you mock this so the code at line (2) and (4) work right? I''m still struggling with mocks but it seems like this can be done. Forgive the naivety of this question. 1. def change_quantity 2. @line_item = LineItem.find_by_id(params[:id]) 3. unless

Hi All, So I just pushed our rails app to our production server, but I''ve encountered a number of problems. Firstly the fast_cgi processes seem to be eating up a hell of a lot of memory, at times max out our 1gig of RAM. I''ve switched back to cgi for the moment, but independently of that sessions seem to be failing intermitently. The session will hold itself stable for a

This might seem really simple to some but just wanted to ask: what is the difference between @session[''user''] and session[:user] ? and how would you use each? And another question, I have the following code: def get_customer if @session[''customer''] @c = Customer.find(@session[''customer'']) end end private def

First of all id like to say hi to everyone from Argentina, im yet another Depot first-timer. Going through the example, i got to the point where my cart finally runs Ajax-based. And there is a line where Dave says, after all the job is done "You should see the cart in the sidebar update. And you shouldn''t see your browser show any indication of reloading the page. You''ve

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

Hi! I''ve understood that the mod_ruby apache module is not recommended for running Ruby on Rails applications. But I haven''t found any information as to why that is so. Please enlighten me. And could you point me to the (currently) prefered production environment. (That can handle both RoR and PHP sites). Thank you and best regards Hans-Eric Gr?nlund -- Posted via

Hello all, I'm trying to install mod_python from the normal channels via RPM, though it seems that download.fedora.redhat.com is down, or moved? DNS reports it does not exist.

Hi all, I have the shopping cart page where a user can add items dynamically through ajax as explained in Railscast episode 75. I am using observe_field to observe the ''quantity'' and ''cost'' fields to update the total field for each item. This does not work however, for records that are added through the Ajax. How can i name the fields and observe them as i have

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

Hi, I am really enjoying the experience of writing my first web app in Rails. I particularly like the instant feedback the framework offers when developing in small increments and I am learning new things all the time. However since I develop alone and my inexperience with rails I?m asking for help to answer some design questions that I have regarding my first app. After reading the Agile

I am trying to use Xapian 1.0.2 with the Python SWIG bindings withn an environment consisting of Apache httpd with mod_python. (not as a CGI) Also this is Linux. Whenever the python code attempts to open a database the entire httpd process will hang indefinitely. The python bindings work outside of the apache/mod_python environment. >From the best I can tell the hang occurs in

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
