similar to: Setter that converts a float attribute to integer

Hi, I have some problems with an application where I''m using custom accessors to do currency conversions. In my model, I have a price attribute in the database that stores the value in cents, to avoid future problems with float arithmetic and round. But at the views, I would like to show the price in euros, with decimal for the cents. So I defined a new attribute called price_in_euros,

Hi, I have a website in production wich uses a lot of date and time calculations to show specific information. The timezone of my hosting service (Dreamhost) is PDT, and the timezone of my potential clients is CEST. There are 9 hours of difference between them.

Hi, I''m looking for a way to extend one of my models to allow some level of abstraction between what goes into it and how it is stored. For example, say I have a Product and I want to set it''s price. A person using the website will type the price in euros. Internally, I''d like to store the price as an integer value of cents. I can currently do this with some ugly code

Hi everyone, just wanted to ask what's the smartest/recommended way of defining getter and setter function *shortcuts* (i.e. something like "[", "[<-") for Reference Class objects? Or is it desired to not use this stuff, but define methods like 'obj$getSubset(row=1:3, col=1)' and 'obj$setSubset(value=x)' instead? I have some example code that might

Hi all, in the help for RClassUtils I found the expression "privileged slots" in function "checkSlotAssignment" with the explanation: /privileged slots (those that can only be set by accesor functions defined along with the class itself)/ I thought all slots of a (not private) class can be a accessed by a user via the @ Operator.

Hi, I have a AR model that I want to limit changes to be only via instance methods that I''ve added. How do I prevent my other sw from setting the instance''s attributes?

I''m stuck in a catch-22 type problem. I have an insert form for a table that uses the validation in the model. i.e. When you click submit on the form and haven''t filled in the required fields then you get the nice rails error messages saying "field can not be blank".

Hi all - To avoid floating point issues, I''ve decided to store monetary values in cents in the database. However, the user will enter these in dollars and cents. Two questions: 1) How do I do the validation for the currency format? It looks like ActiveRecord truncates the cents since it thinks the field type is a Fixnum. Am I forced to do validation in the controller? 2) Where
