For example, given the following: class Message < ActiveRecord::Base composed_of :sender, :class_name => ''EmailAddress'' composed_of :recipient,

Hi, I think the columns and table in migration should be able to have an optional "display_name" set manually. Something like: create_table :people, {display_name => "Personne"} do |t| t.column :first_name :string, :display_name => "Prénom". end Let me explain my point of view: Rails is a framework made to write programs in English.

I would like to say that LLVM has been extremely useful for the development of the compiler and so thank you everyone for building this amazing system. ---- Virtual Method Calls ---- While most aspects of the language map well onto LLVM IR, it seems

Hi, I have a database table and associated ActiveRecord model. I was trying to store (temporarily) an array in one of the attribute elements - not to save it, but just so that I can keep some form data in a sensible place. A stripped down version of the problem I''m having is: p = Property.new(:bedroom_count => ["2","3"]) puts p.inspect # ==> will correctly show

Hi all.... Admittedly I''m new to Rails and trying to find my way but I''m having an issue with uploading documents with attachment_fu. I have a form where I''m uploading multiple attachments (using AJAX to add file_filed_tags). That seems to work pretty well. The problem is I can''t seem to get the content_type to work as I would expect. For example, if I use

Hi, When we update a record via an update form, is there an easy way to find out the fields that have been changed. If the update is successful, i want to display: The following fields have been changed: field-name = new-value ... Thanks, Lantis. -- Posted via http://www.ruby-forum.com/.

Some of the data in names and string values were being unsafely printed, causing some types of XML processors to fail (e.g. Python's Expat). This patch checks for printability of each character and outputs base64 with an encoding attribute for unsafe data. --- xml/hivexml.c | 75 ++++++++++++++++++++++++++++++++++++++++++++++++-------- 1 files changed, 64 insertions(+), 11 deletions(-)

I''m building an app that needs i18n support across the entire database (i.e. localized attributes). In order to do this I''ve created a special HABTM join table that can be associated with _any_ other table: create table language_strings ( for_table varchar(255) not null, foreign_id int not null, language_id varchar(5) not null, attr_name varchar(255) not null, value text

Hey.. So I have a model that has a lot of number fields. Each of these go through a process when read in and read out to add/remove commas (between every three numbers) to make them more readable. The getter I currently have is like this: def sale_price Listing.insert_commas(read_attribte (:sale_price)) end and the setter is: def sale_price=(price) write_attribute(:saleprice,

I have a model object for which I would like to effectively hide one attribute (a password hash) so that it is never returned by a find_* call. I have tried several unsuccessful means. Is there a simple way to do this that I am overlooking? Thanks, Doug

Hi all I''m having an authorization method that looks like the following: def user_requests_authorization_to(right_name) ... end I find it boring to always use user_requests_authorization_to(''EDIT'') user_requests_authorization_to(''CREATE'') etc., so I thought I could implement my own dynamic method, like the dynamic finders! Instead of the calls

All, I have a RXML template which renders partial RXML templates within it. A snippet is below. The "xml" variable is the parent template''s Builder variable. It is passed into the partial under the name "parent_xml". Why can''t I use :locals => {.... :xml => xml ....} in my call to render the partial? It seems like if I do use :xml => xml, it

I''m working on the plugin for RBatis and a new little thing I''m toying around with called ActiveMessaging (sorry, David I stole the name from you from the TW AwayDay ;-)). Anyway, in both these applications I want to be able to have reloadable classes that don''t extend any of the standard built in ones. So, I don''t mean to offend the Eminent Core Members by

Regarding validates_associated... Let''s say I have: article belongs_to author But for whatever reason, I want an article to also be written anonymously and therefore not require an author. Then I have: Article: belongs_to :author validates_associated :author But I DON''T have validates_presence_of. What I want to do is validate that an author is valid --if it is
