Hello, I''m running Mongrel 0.3.13.3, cluster 0.2.0, and Rails 1.1.6 and I have a problem with a sweeper not having access to the controller instance. NoMethodError (undefined method `session'' for nil:NilClass): /app/models/audit_sweeper.rb:16:in `log'' /app/models/audit_sweeper.rb:9:in `after_update''

Hello everyone, I am currently struggling with the following issue that only seems to appear in my production environment: When attempting to send a mail from an ActionMailer the template location algorithm does not seem to pick up the corresponding template: ActionView::MissingTemplate (Missing template event_mailer/approval_requested_notification.erb in view path app/views):

I was just wondering what about a report that I made almost 2 months ago: Active Record observers broken<https://rails.lighthouseapp.com/projects/8994/tickets/4087-activerecord-observers-cant-be-used-for-before-callbacks> I think it''s a pretty big bug. In Rails 3, creating an observer with a "before_save" callback (for instance) will result in all observed models being

Sorry, that name is a misnomer. However, I was excited to find that Ruby has a built in Observable module and I''m pretty bored, so I apologize in advance.... require ''observer'' # one who is observed class Celebrity include Observable attr_accessor :name attr_reader :is def is=(val) @is = val changed notify_observers(self) end end # one who

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from ActiveRecord::Base inherited class. Code: class EinsatzFilter include ApplicationHelper attr_reader :personen, :monat, :projekte, :kunde

hi all I''m running background tasks using BJ 1.0.1 (gem version). On some requests, the tasks are executed as expected. On others, I get the following error: RuntimeError (no bj found in ["/u/apps/igniter/releases/20080408205801/ script", "/bin", "/usr/bin", "/sbin", "/usr/sbin"]): when it runs, it runs fine but does anyone know what

Hi, I am trying to create Bid/Ask for each second from a high volume stock and the only way I have been able to solve this is using loops to create the target matrix from the source tick data matrix. Looping is too slow and not practical to use on multiple stocks. For example: Bids Matrix (a real one is 400,000++ length): Bid Time 10.03 11:05:03.124 10.04 11:05:03.348 10.05

Okay I''ve been working on a little biding system. In my model I have class Item < ActiveRecord::Base has_many :bids def highest_bid @bid = 0 self.bids.each do |bid| if @bid == nil @bid = bid.max else if bid.max > @bid @oldbid,@bid = @bid,bid.max end end end if @oldbid == 0 "#{@bid} - #{@oldbid+1} = #{@bid -= @oldbid+1}" else dif =

Where is the best place to solicit bids on a mid-size web app? (budget ~$15,000) What is the appropriate protocol for posting RoR RFPs? Thanks! Taylor -- Posted via http://www.ruby-forum.com/.

Okay first off here''s the error: You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occured while evaluating nil.- Here''s the code in the model: def highest_bid @bid = nil @oldbid = 0 self.bids.each do |bid| if @bid == nil @bid = bid.max else if bid.max > @bid @oldbid,@bid =

I have a ton of Nortel MICS/CICS phone systems and am looking for an easy way to integrate them. Two questions arise: 1. Is it feasible to use asterisk as a Man in the Middle for a T1 PRI system? The idea is to intercept outbound calls from the Nortel PBX and redirect them via VoIP to another asterisk box at another branch transparently(thus saving the LD cost). Otherwise I'd pass

Hello I am reshaping a data.frame bids --> reshaped as shown below. I thought this should be possible with a single invocation of reshape, but the only way I came up with is reshaping subsets for each keyword and then joining them together. Does anyone have an idea how to solve this in a more elegant way? Efficiency is a concern as the datasets are very large. Is there a way to specify

I want to code the following task: I have a class, for instance, class A with is a observable. I want to add a controller of my rails system to this class. So I can notify_observer, and it updates all controllers of my system. How do I pass a controller as a parameter to the add_observer() method? And where I put this code? Thanks in advance.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a medium sized business that is interested in implementing * as their PBX system. They currently have a Panasonic system with Panasonic handsets that they are going to replace Asterisk with, as the current system is maxed out, and they don't even have voicemail capabilities. I have been considering using an Adtran Atlas 550 with FXO and

We're looking at replacing some old APC SmartUPS 5000s with something that has USB so NUT can more easily talk with it (and yes, I've tried USB-RS232 adapters and every one I tried started kicking out errors within a few hours). One of the bids we have is for a "Tripp Lite UPS Smart Online 5000VA 4500W Rackmount 5kVA 200V/240V" as the potential replacement unit. I have no

Package? Quantmod. In the subject line. I agree that they look like dates, I don't know how to determine if they are actually dates. Josh Ulrich usually answers questions along these lines very informatively and quickly. One reasonable course of action is to wait to see if he does the same with this one. --JJS ________________________________ From: Bert Gunter <bgunter.4567 at

You know options but you are confused about maturity dates, i.e. expiry? In information in that list (ie along the date dimension) is the expiry; at each date you have another list for both puts and calls, and inside each of those a grid given by the

Hi all, I''ve been offered a short-term contract here in the North of England - around 3 months work, but with RoR I think it will take considerably less time - and am just curious what market rates were right now. I''ve been offered a little under ?1k/week which seems ''right'' for a PHP coder doing this kind of work, but should I be hitting for more, or is

Hi, I keep getting locking errors when updating my index which puzzles me since only one process is supposed to be accessing the index at a time (at least in development mode). I''m using Ferret with Rails (NOT acts_as_ferret, though) and employed an observer to add a new document to the index when a new ActiveRecord is created. I''m not sure if this has any impact on the
