Active Record, Migration, and Translation
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. You see it when you

Comment.all returns array of what?
I have a bad feeling asking this but I did not manage to find an answer myself :/ @comments = Comment.all @comments is an array. I can for example access comment.created_at directly, or I could do: <% @comments.each do |comment| %> <%= debug comment["created_at"] %> <% end %> I expected comment to be a hash, but comment.keys or comment.values fail, as well as an

Newbie worries with "Developing Rails Applications on Max OSX Leopard"
Hello There, As a new comer to RoR, I started to follow the article http://developer.apple.com/tools/developonrailsleopard.html.

Automatted Getter/Setter
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,

SQL injection with :order, :limit, :group
I know how to avoid SQL injection attacks when you use :conditions User.find :first, :conditions => ["login=?", params[:username]] but how about with :order, :limit or :group? # uh-oh...spaghetti-oh User.find :first, :order => "login; delete from users; select * from users" Pat --~--~---------~--~----~------------~-------~--~----~ You received this message because you

ActiveRecord attributes -- strange behavior when adding Array to an element
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

attachment_fu content_type problem
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

Validation with Aggregation
ActiveRecord supports composed_of for value objects which is fantastic but one thing that it doesn''t seem to support (or at least I am unable to find any documentation for) validation of the value objects. For example, given the following: class Message < ActiveRecord::Base composed_of :sender, :class_name => ''EmailAddress'' composed_of :recipient,

[PATCH 1/1] hivexml: Base64-encode non-printable data
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(-)

Storing BigDecimal in the db
I need to do some precise math, going to 12-14 decimal places, so I''m using BigDecimal. How can I store this in a db? I''m using postgresql 8.1.0, if that matters at all.

Easy way to handle form input without a model class?
I have a couple forms that I''d like to be able to validate and automatically populate, but it shouldn''t be based on AR. In fact I often have a bunch of small forms that I can''t really justify writing a whole new model class for anyway. I''d like to validate the form input, and then use rails helpers to automatically populate the form if validations fail.

RXML partial question
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
