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

With rspec 1.0.8 I have a spec in the directory: spec/units/controllers/application_controller_spec.rb require File.dirname(__FILE__) + ''/../../spec_helper'' class DummyController < ApplicationController def index raise "Prevent index from rendering" end end describe ApplicationController, "Handling errors in production", :behaviour_type =>

So far I''m disappointed with what I see as red flags. I follow along what seems like foolproof instructions. I install everything, rails new /some/new/app cd to the directory and rails server and my worst fears cryptic useless stack trace...so I copy the top line, search for stuff on this sqllite3 adaptor to fix it, I type the gem install command it mentions (gem install

When i start the server "rails s",following error message appears: => Booting WEBrick => Rails 3.0.7 application starting in development on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server Exiting /usr/lib/ruby/gems/1.8/gems/actionpack-3.0.7/lib/action_dispatch/routing/mapper.rb:167:in `default_controller_and_action'': missing :controller

Hi folks. I''ve just started using rspec and I have to say it''s very nice. The thing is, I prefer mocha''s mocking dialect. So I thought a simple require ''mocha'' would set me up. Unfortunately, rspec does all its goodness using do/end blocks in anonymous classes, so it wasn''t quite that obvious. Anyway, here is the incantation I ended up

Hi all, New wxRuby event handling offers the choice between using blocks or methods seamlessly and easily. This is great respectively for simple app and more complex app. Nevertheless, currently the creation of an application, a frame, or a dialog is very tedious for simple app : - you need to create a subclass of Wx::App, Wx::Frame ... - you need to put the initialization code in the initialize

My app works fine in development on my laptop but in production on my server I get "We''re sorry, but something went wrong. We''ve been notified about this issue and we''ll take a look at it shortly."

Hi all, I''m running an application on my localhost, but the command "rails server" behaves very inconsistently. About an hour ago it ran well on another app, but got errors now. According to the errors it seemed that the server began to run but the there is something missing in the library. But I''m very new to Rails so cannot figure out what do these lines mean:

Hi I am trying to use the RSS classes from "rss/2.0" and everything works but I want to know what attributes and properties I can get at from each of the classes I am getting back. For example, the class has a "channel" which I can tell has a "title" attribute (because it works when I query it :) but I would really like a list of every attribute that is

Hi. I''ve tried to redefine the method belongs_to in ActiveRecord::Base, so every time a model is defined as belonging to :attachment, it should have some additional methods. I tried to do an alias of belongs_to, but this was not successful. The error message in Webrick was > Booting WEBrick... ./script/../config/../lib/ActiveRecordExtensions.rb:67: undefined method

When trying to understand a piece of code from the Ruby-On-Rails framework, I found that I''m still lacking knowledge about scope issues in Ruby.

The new router in Rails 3 is clean and concise and marks the acceptance of instance_exec as a method for writing a gorgeous DSL. I''m wondering should something similar be applied to the default form helpers? Moving from this: <%= form_for(@post) do |f| %> <%= f.text_field :title %> <% end %> to this: <%= form_for(@post) do %> <%= text_field :title %>

I have developed a rails application for my company. It will be used by upto 3o people at a time. I have just read that Mongrel will only process 1 request at a time (rails is only in 1 controller at a time). Does this mean that to get good performance i need to run mongrel many times on different ports? How many different instances of mongrel is recommended? If this is true then it

Hello, I needed to add custom cache field for one of my application. I thought I will share the code showing how to do this. This code below creates and maintain a custom cache field, for keeping track of totals. Say, you have accounts, and for each account there are transactions (either deposit/withdrawal), and one will like to keep track of the total balance for an account. So, let there be a

I have the following code, which yields instance eval''s the block given: class Foo def bar(&blk) instance_eval &blk end def baz yield end end The effect of this is that self is reassigned: Foo.new.bar do # here, self is the instance of Foo # created by new end But normally self is the object in which Foo.new.bar {...} occurs.
