Polymorphic associations and single table inheritance
Running into an interesting problem that at first glance appears to be a
bug in the AR association code. However, it''s explicitly coded this way
so I''m not so sure.
I have some code like this:
class Address < ActiveRecord::Base
belongs_to :addressable, :polymorphic => true
end
class Person < ActiveRecord::Base
has_many :addresses, :as => :addressable,

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

has_many reference
I am trying to do something right from Agile Web Dev with Rails book
and it does not work. I must be missing something obvious.
I have a one-to-many relationship:
class Draft < ActiveRecord::Base
has_many :endorsees
end
class Endorsees < ActiveRecord:: Base
belongs_to :draft
end
>From my reading, methinks I should be able to say:
d = Draft.new
d.endorsees << Endorsee.new

Unicode Support for MS SQL Server
In order to coerce Rails 1.2.x into supporting Unicode values for an
attribute in a model, I found I had to do the following:
1) Change the underlying column type from varchar to nvarchar.
2) Prepend any quoted values going into nvarchar columns with a
capital-letter-N, e. g. ''unicode'' becomes N''unicode'' In order to
accomplish this, I modified

[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 :
class Division < ActiveRecord::Base

Assigning to the foreign key on a belongs_to association
I''ve encountered what seems like an odd omission in the behaviour of
belongs_to associations: if you assign to the foreign key attribute,
it doesn''t update the associated object (or mark a previously loaded
one as stale) until you explicitly save or reload it.
Let''s say we have a Company model, which belongs_to :city :

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.
I''ve attached to code at the end of this email. Suffice it to say I need to
use the standard

How do I combine :finder_sql and :conditions to perform a sub-search on a custom has_many relationship?
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''.

Why does AR use base_class for polymorphic relationship "type"
I have a couple models that inherit from a base class that then
inherits from AR.
When they are used in a polymorphic relationship the "type" is always
the base class.
Just curious if anyone has a reason why it doesn''t use the *actual*
class rather then the base_class. I have patched AR to use the actual
class if !base_class.table_exists? but it adds another query each time

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

Passing an SQL fragment in AR save
I have a basic model class TestTime with no customization.
class TestTime < ActiveRecord::Base
end
I would like to pass the following SQL fragment as part of an AR save
call to TestTime objects. How and where would I do this in the model?
"set c_time=current_time"
(current_time is an SQL method, not a variable).

has_many, :finder_sql, setting attributes
Hi all,
My question is somewhat complicated, but bear with me. My project has a
number of models: User, Program, and Team. Users belong to multiple
Programs. Programs have multiple teams, but Teams belong to one
program. For each Program a User belongs to, he can belong to multiple
Teams. (Think of this in an athletic context where users are athletes,
programs are universities). So my

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:

: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]}"

finder_sql issue with has_many :through

Is :finder_sql using #{id} broken?
Hi All,
It seems that :finder_sql in a HABTM association only interprets a
single quoted #{id} the first time through a query. I see examples
of this being used in a few places (though with has_many) and I don''t
really see how to use :finder_sql without a #{id}.
Am I missing something or is this just broken?
