Help with encryption
So I have this key information that I got by generating a private and
public key in VB, but it gave it to me in the form of a modulus and
exponent in an XML file. Now, I need to encrypt some stuff in ruby using
that info. On this site:

they explain how to do that, but clearly this info is

How should I select rows from a join-model based on more than one association?
A concrete example:
We''re building a system to organize the information about workshops
being held in various conventions. A convention has more than one
workshop, and each workshop can be held in more than one convention.
Also each workshop has a host, who is specific to a workshop being
held in a specific convention.
For example, Matz may host an "Introduction to Ruby"

has_many :through and foreign key parameters
I just took my HABTM and turned it into a :through since my join table
has another "non-joiny" attribute.
I went from this:
has_many_and_belongs_to :jobs, :join_table => ''tablename'',
:foreign_key => ''x'',
:association_foreign_key => ''y''
to this:

Adding Custom templates?
Hi, does anybody have any pointers on where to look to learn how to

Self-referential has_many :through relationship
Hi,
I have a self-referential has_many :through relationship setup to
track relationships between users. Basically relationships are
modeled as a join table with an extra column ''relation''.
create table relationships (
user_id integer unsigned not null,
friend_id integer unsigned not null,
relation char(1) not null,
)

Custom date format
Hi, I''ve followed these directions :

It seems pretty straightforward but obviously it doesn''t work for me...

many-to-one relationship, do I need a second table?
Ok, to keep things short. Im wondering if I need a secondary
relationship table to handle my many-to-one relationships. Here is an
example of what I''ve written down. For instance say I want to find all
of the people in a given location.
class Location < AR:Base
has_many :people
end
class Person < AR:Base
belongs_to :location

habtm on an array (or object.habtm.habtm)
Hi,
I have three Models: User, Group and File.
User habtm groups
and
Group habtm Files
How can I find all files that a particular user has access to?
eg user.groups.files ?
As user.groups returns an array, the above doesn''t work.
Id like to find the files for all groups in that array, without adding
any code to the User model.

How do I substitute variables into class names?
In a partial that renders another partial, I would like to change the

<%= render :partial => "skills" %>

If item = "skill" would like to do something to this effect;

has_many :through with a polymorphic join
Hi,
Four tables: users, user_counties, uk_counties and us_counties.
Each user has many counties, and each county has many users, so I
decided to make user_counties a polymorph, so it can have counties
from different countries (each country requires a completely different
set of tables with a completely different set of properties, that''s
why there''s one table for uk_counties and

Changing default date format in Rails
I''ve spent all day digging through the rails api and postgres-pr on
this, I think it''s time to ask the list.
Postgres stores a Date in YYYY-MM-DD format. My users want the dates
in MM/DD/YYYY format.
Sure, I could explicitly convert it on the app level every place where
a date is displayed, but that seemed like a DRY violation.
I thought I''d be clever and simply

find() with id array - can i preserve the ordering?
Sort of a newbie question - sorry if it''s been asked before and I missed it
in my search.
I have an id_array of Author ids, and I want to retrieve the associated
Author models as quickly as possible, but also preserve the ordering of the
id_array.
Using Author.find(id_array) returns the records, but not in the same order.
Is there some flag I can pass to find() to preserve the order? I

how do I model self-referential entities?
Hi all -
I am having some trouble figuring out how to model self-referential
entities in Rails.
I have a "group" model, which can have 0 or more "group" objects or 0 or
more "user" objects.
I tried creating a subgroup table that has a parent_group_id and a
child_group_id as foreign keys but can''t figure out how to create the

HABTM join table has an "ID" column - is this an issue?
All,
I''m building model objects for existing tables that I cannot modify.
In AWDWR, Dave says "Note that our join table has no id column...The
second reason for not including an id column in the join table is that
AR automatically includes all columns from the join tables when
accessing rows using it. If the join table included a column called id,
its id would overwrite the id
