has_many + finder_sql & :include
Hello,
In a model I have:

bug in has_many count?
I can submit a patch, but wanted to confirm I''m looking at this right...
The docs indicate that if you specify a has_many association with
:finder_sql, but no :counter_sql, it constructs the appropriate counter
sql by substituting the SELECT clause.
But has_many_association.rb doesn''t seem to do that -- it just passes
Base#count_by_sql the finder_sql, which doesn''t

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
have two tables with two parallel one-to-many relationships. I wish to
use the :finder_sql parameter to essentially ''or'' the two foreign
keys.
What isn''t working for me is performing a ''sub-search''.
Let''s say the tables are "stores" and

[AR] #{id} namespace visibility used in finder_sql
Dears,
[Rails 1.0.0]
I''m working with a legacy schema, and around my 20+ models i''ve used
some AR constructs.
They are based on a finder_sql doing some dirty sql and using #{id}
from the ''pivot'' model for extracting data in other tables.
like :

legacy database and finder_sql nightmare!
This is my first rails app with a legacy database and I''m having a
terrible time getting the models set up correctly. I have an order
table that has a primary field named order_number. I have a name table
with a primary of item_number. These two tables are liked by the
item_number and the order_number, but not as you might think. If the
order_number is 2500, then each entry in

It this possible: finder_sql-like behavior for belongs_to?
Guys,
I have a need to support as has_many/belongs_to relationship on a
legacy(kind of) schema. The reason I say kind of is that the schema does
have "id" columns that are used in many associations, but this particular
has_many/belongs_to association needs to support different ones.

has_one
I''ve got an order model that stores order data.
One piece of data is a credit card type, which is a digit 1,2 or 3.
I have a cardType model that has an id, shortName and LongName for the
credit card merchant (visa, mastercard, amex).
I want to be able to say: order.cardType.shortName, but can''t seem to
get has_one working. It works with has_many and a finder_sql statement

HABTM with finder_sql problem (Rails bug?)
I''m building an app that needs i18n support across the entire database

OT: List of VoIP providers?
I have been looking around for VoIP providers but have not found a good
listing.
Is there no "yellow pages" for VoIP providers? Google mostly returns
services
like Vonage, Packet8, NuFone, ect. None seam to be very reseller
friendly and
none offer LNP or local DID's for my area. Anyone know of a list (even a
partial one)

has_many with :finder_sql question
hi all,
I have a Class, Client, which has_many projects (Project class). the
projects depend on a session_id variable, however. So the question
is, how can I do the following:
has_many :projects,
:finder_sql => "SELECT p.* FROM projects p INNER JOIN
projects_users pu ON pu.project_id = p.id WHERE pu.user_id =
#{session[:user_id]}"
The problem is that I need to filter a

exposing id''d
I have been working on a small app that started with some scaffolding.
Some of my actions still have the structure where the id''s of things are
passed on the url for gets.
Whats the best way to avoid the security problems that this creates?
I am sure that there are many pages written on this topic but I guess I
have been searching for the wrong things.
Thanks

has_too_many
Assuming you have Person that has_many :messages, what will it happen if it
has 10000 messages?
Will rails attempt to initialize @person.messages with 10000 rows from
database? If that is the case, is combining finder_sql and counter_sql the
common practice to avoid this?

Linux installation
I have just installed R under Linux and had a tricky time finding out
that I needed to install r-devel as it was not suggested by yum and does
not appear in any of the FAQs. Everything was fine until I tried to
install tseries then I was told in the compiler output that R.h was
missing. Obviously a search on Google proved fruitless and I was forced
to ask on r-help. I am now kicking myself, of

Let''s say I wanted to get all the categories a certain user posted in.
How do I get that information withouth using a custom query
