Problems with STI in has_many/belongs_to in Rails 1.1
I have a problem that surfaced in my attempt to upgrade my application
to Rails 1.1.
We have a STI model on the "belongs_to" side of a has_many/belongs_to
relationship. All my unit tests for this model pass, and the
relationships all seem to work fine.
But in my functional tests, I''m getting errors. I''ve traced it back
into the call to the has_many

Relationships: one model referencing same table for different data sets?
Hi,
After I''ve saved, I want to display the Description from the Codes table that
corresponds with the ID in the Cause table.
Rails doesn''t seem to like that, because on my form, I have two sets of data in
combo boxes that come from the Codes table. So, in the show template, I can''t
do this:
Cause of Death: <%= @cause.code.description %>
Any ideas?

Authentication design/ideas
Hi all,
I''m using acts_as_authenticated for the front end facing part of my
site. I have a model called Customer. I now want to protect the admin
sides of things. I am thinking of using Ezra''s acl plugin
(http://opensvn.csie.org/ezra/rails/plugins/dev/acl_system2/README)
for this. My only problem is that I don''t want the model for admin

(Dreaded) STI, belongs_to
Having problems with STI. Names below have been changed to protect the
innocent. Imagine a system that allows someone to apply for one of two
different types of school scholarships. Each scholarship goes through a
different review process, represented by a state machine (this is not a
state machine question). So there are two state machine classes that
differ slightly and subclass a generic

Crazy @55 Inheritance
I have one table, called "people".
Within this table, there are type "users", "managers".... etc. So, basic
STI.
Now, I want a "user" to have one manager, but a "manager" to have many
"users".
Since I don''t want to use HABTM... how do I set this relationship up seeing

[Req] polymorphic associations howto
Hi people,
I''m looking into polymorphic associations as a way to cleanup some
messy parts of my code. I think they will allow me to do exectly what
I need, but since there''s little to none written on this subject, I''d be
delighted if someone could shed some light on this. Especially what
the different options and needed table structures need to be.
Thanks,

Namespacing Models
Hello everyone,
Do you feel it? The little shiver down your spine when you think of
"namespacing" in rails? To some thats a common feeling, to people like
myself who enforce absolute organization have already thought about
the need for namespaces in rails.

Controllers and routes, from my experiences work well, that being,

some strange behavior for has_many with STI

I''m having some trouble with a has_many association on a table using
the single table inheritance model that I''m hoping someone can help me

`id` int(11) NOT NULL auto_increment,
`user_id` int(11) default NULL,
`type` varchar(20) NOT NULL default '''',

Building a library system (ActiveRecord question)
I''m rebuilding a library/academic system (including public web) using
excellent Rails. I''m trying to make the most out of ActiveRecord, but
rethinking the database schema spawned some potential issues that may
cause problems down the road, so I want thoughts on this from more
experienced community.
The thing is, all entities in the system have a fixed set of metadata.

Trouble combining :has_many, :finder_sql and :conditions to create a sub-search
I''m sure there''s something right under my nose that I''m missing. I

use the :finder_sql parameter to essentially ''or'' the two foreign
keys.
What isn''t working for me is performing a ''sub-search''.

Can acts_as_ferret search only one of the inherit models in the
hierarchy of STI models? Say you have Contents, with types articles and
comments. I know that you do Contents.find_by_contents, but can you
also create indexed for Comment and Articles?
Thanks for you help
