Hi everyone, I''m new to Rails and Ruby, and have been working my way through the Pickaxe and Agile Rails books for the last week or so. With a background in payroll apps I found that the default ActiveRecord mapping of decimal columns to float variables really bothered me! Financial calcs need high levels of accuracy and floats just don''t give you that. I know there are a bunch

I''m thinking of experimenting with some currency conversion. However, I''d like the conversions to be in synch with the current rates. Anyone know (and this maybe out in left field) if there is some online (perhaps xml) or other data stream I can connect with in my code to output values based on user selection ? TIA Stuart

Hi Let''s say we have model Foo. Each Foo instance can have several bars. Those bars are primitive, so they shouldn''t be models. For example, Foo might be a type of convention, and the bars might be years the convention was held in. Naively, we would have a conventions_years date, and put: has_many :years inside class Convention. But then we''d get an error, since for

Does anyone know the best way to track time zone information. There doesn''t seem to be much documentation on this. So far it seems like a simple db field like create table accounts ( id int unsigned not null auto_increment, name varchar(50) not null, time_zone varchar(50) not null, ... primary key (id) ) and a class like class Account < AR ...

Hello all ! I have a model being validated that spits it''s error messages on the resulting page using: error_messages_for(:mymodel) .... Basic stuff. It''s working perfectly. Now, I have something else I want to check on the same page (that isn''t an attribute to the Model)... and am trying to add it using: @mymodel.errors.add_to_base("another error here")

I''ve got a couple apps that I use (billing app, support ticket app, some other custom apps) that I want to integrate into one site. They will all use the same layout for the most part, and will link between each other. When I initially thought of doing this, I figured if I put the apps at different roots - /billing /support etc - then the links wouldn''t work at all, because

How are you guys handling threads or server processes that have to, for example, process the data in your application on a periodic basis? Cron jobs can do it and then run on the database. But, are there ways to launch threads within the rails application itself. I have heard of WebBrick ways, but I am working with lighttpd, fastcgi? (textdrive if you are really interested).

I have three Rails apps on my laptop. Two can runs tests just fine. The third generates this error when I try to run any tests: > /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/ > active_support/dependencies.rb:200:in `const_missing'': > uninitialized constant Test (NameError) > from ./test/unit/../test_helper.rb:5 > from

These items has some boolean fields for example, and would like to have a checkbox at the top of the window to let me select how to filter the list. here''s what i put in my controller if @params[:filter].nil? @params[:filter] = { ''sent'' => "1"} end ... generate the corresponding

Hello all. I''m a seasoned system administrator and have no fear of building source packages on a variety of platforms, but RMagick has, until recently, evaded all of my attempts to building it on my PowerBook. Someone else just mentioned that they had trouble with RMagick on OS X (Intel, don''t really know if my advice will help) so I decided to post a HOWTO to the list. I

I would like to have a login box setup so that if incorrect info is submitted, the box "shakes" via Effect.Shake. If the correct information is submitted, I want to redirect to some other page. The only solution I''ve found is the following, which is pretty ugly, as it displays the javascript I''m invoking on the page prior to the redirect. Here is the code: The Form

Hi All, I am looking for a way to dynamically load a view, inside a template, based on uri that does not officially exist inside of rails. i.e. a typical CMS system such as wordpress that stores the html from the pages in a database. I have found a page on the the rails wiki ( http://wiki.rubyonrails.org/rails/pages/HowToRunAnActionBeforeRoutes) that seems to be what I want, but lacking a few

Hello ! I''m trying to implement something similar to the "multiple updates" section of the Web2.0 chapter of the Agile book. I implemented my version, and nothing is happening. No javascript errors, my logs look fine, page is rendered fine... just no Effect.Highlight. Here is the code: views/causes/cause_home/index.rhtml =============== <%= form_remote_tag(:complete =>

Hi all, A little question. How can u use an constructor in controller? I would like to initialize some central stuff before i''m processing the controller. thanks in advance, Martijn

I''ve implemented Ferret, using the instructions here: http://wiki.rubyonrails.com/rails/pages/HowToIntegrateFerretWithRails I get no errors in the application at all... however, I always get 0 results. I built an index off of some data, it exists in the index/ directory, the form submits find... etc... Just 0 results... all the time :) I confirmed the data from my models is being put

Hey All ! I have a form which contains two models. I would like both models to be validated, but have their validations aggregated on the page. If I do: <%= error_messages_for(:model1) %> <%= error_messages_for(:model2) %> It puts two big validation blocks on the page. I would like all the errors from both models, but only in one validation box. Is this possible ? All my attempts

I read in various places that although migrations aren''t transactional, all you need to do is wrap you migration method in "ActiveRecord:: Base.connection.transaction do" to make the self.up or self.down transactional. In my experience (Rails + PostgreSQL), this doesn''t work very well. If my migration hits an exception, any tables that were touched remain modified.
