Hi list, long time no see! :) I was looking for an email reminder script for users whose password will expire. Some of our users are on long travels and will never see the Domain's default notification. I haven't found any complete (and simple) solution online. So I wrote one. In case it helps anyone, you find it below. You should only have to fill in the blanks for the the

Hello developeRs, Apologies in advance for a rather long email, but to describe the problem, I need to step through many details. I have been working on a new dispatching system (futile.paradigm on CRAN) based on functional programming concepts that is an alternative to S3 and S4 dispatching. I use a declarative syntax using guard statements to control the dispatching between function variants. I

Any idea why this calculates the integer the way it does? irb> ("291.15".to_f * 100.0).to_i => 29114 Thanks, Tom -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi, I have a few questions regarding REST and the Authenticity Token. I''m using a RESTful aproach for my small project and everything worked fine untill I wanted to destroy a record. Lets say we have a listing of folder (a folder is just a record) and I want to destroy one by using this link: <%= link_to image_tag(''icons/folder_delete.png''), {:url =>

So, I''m personally cool with this change (patch from #5454, applied in [4596]), and I''ll make it work for Oracle tomorrow. But just wondering if folks considered the performance impact of the change? From a simple test it seems that BigDecimal math is about twice as slow as using Floats.

Hello How can I test equality with two objects when they include some attribute that is BigDecimal? if I make something like this: it "should ...whatever" do obj = Factory.create(:my_object) ... MyObject.first.should == obj end. FAILS This fails because the object expected is different from the object gotten, and the only difference are the BigDecimal attributes, that are

Hi all, I''m working on a financial app, and have set up some columns in my tables as decimals with precision => 8 and scale => 2. My migration looks like: change_column :lineitems, :price, :decimal, :precision => 8, :scale => 2 change_column :payments, :amount, :decimal, :precision => 8, :scale => 2 I''ve run the migration and restarted the server.

I''m doing the depot example in the Agle Web development book. I''m getting this error: "undefined method `product'' for #<BigDecimal:331ce70,''0.21E1'',8(8)> " "Extracted source (around line #9): 8: for item in @items 9: product = item.product 10: -%> 11: <tr> 12: <td><%= item.product%></td>"

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

Hiall, I''m wondering what''s common practice when dealing with money values stored in databases. I like the idea of storing all the values as integers, i.e. all the values in eurocents not euros. Then I need to multiply all values the users enter by 100 before storing them in the database. Now the question is, what''s the most efficient and dryest way to do this?

I''m working my way through the book Agile Web Development with Rails, and I am in the section where the book has me creating a display_cart method and the associated view. When I copied the code from the book into the view, it threw this error. If anyone could give me some hints where I should be looking I''d appreciate it. NoMethodError in Store#display_cart Showing

Hi, I was wondering if it is possible to output validation errors in a nested form? I suppose this should be possible, but I am experiencing an error message that I can''t track down.
