Problem with ActiveRecord and Associations
Hi,
I''m having what I believe to be a typecast problem with ActiveRecord and
Associations. In the code below, I need to flag a contact record for
deletion if the contact doesn''t have any addresses or books records:
sql = "select id, delete_flag from contacts where id = #{params[:id]}"
contact = Contact.find_by_sql(sql)

Handling instantiate_without_callbacks
Hi,
I''m writing this app with inheritance. I''m using the type column to
store the class name. Another app scans the app and performs actions.
However, it is possible that the second app does not implement a
class, in which case, the superclass should be instantiated. Now I''m
getting:

How to use arbitrary relationships in Activerecord
How can I ask ActiveRecord to make it''s "has_many" code to work on some
arbitrary relationship between two tables? ie neither field is a primary key
The situation is that I am writing a Postfix management application and
one of the tables to manage is the "alias" table. My primary key in the
"mailbox" table is "id", but the alias table is just

and_yield + instance_eval(&block)
I have the following code, which yields instance eval''s the block given:
class Foo
def bar(&blk)
instance_eval &blk
end
def baz
yield
end
end
The effect of this is that self is reassigned:
Foo.new.bar do
# here, self is the instance of Foo
# created by new
end
But normally self is the object in which
Foo.new.bar {...} occurs.

Adding more sugar to wxSugar
Hi all,
New wxRuby event handling offers the choice between using blocks or
methods seamlessly and easily. This is great respectively for simple
app and more complex app.
Nevertheless, currently the creation of an application, a frame, or a
dialog is very tedious for simple app :
- you need to create a subclass of Wx::App, Wx::Frame ...
- you need to put the initialization code in the initialize

instance_eval and Proc objects
Hi All,
Got a bit of a Ruby question for you.
If I have a function that makes a proc object like this:
def select(selector, &proc)
el = Element.new
el.instance_eval proc
end
select("#thing") do
hide
end
Wat I want to do is evaluate the Proc in the context of el but this
doesn''t work because instance_eval accepts a string or a block and not
a Proc object. I sense

ActiveRecord, instance_eval, and PStore
I''m trying to add some per-object behaviors to objects descended from
ActiveRecord, by using after_initialize() and instance_eval(), like this:
def after_initialize
self.instance_eval(File.read(''customers/default.rb''))
end
(Ultimately the file path will be dynamic, this is just proof of concept.)
default.rb just contains a few method definitions like this one:

Rails is doing what I want - but I don''t understand how.
Hi guys, I have the strangest thing happening. The funny part is its

ActiveRecord outside of rails
I have a few questions regarding using activerecord outside of rails.
Usage is with legacy databases, which gives rise to some of the
problems.
Probably the first, and most simple question though, is how to capture
the SQL log, with which I can hopefully figure the other stuff out.
I''m currently trying
ActiveRecord::Base.logger = Logger.new STDOUT
Based on random googles, but it

Serialized object behaves weird
Hi!
I got a class named EinsatzFilter which I serialized to session. Before
saving to session it works afterwards I keep getting the message:

ActiveRecord::Base inherited class.
Code:

Another ''found a bug'' problem - This time with user purging.
Ok, given the statement on the web page about unlesssystemuser under
Resources (
http://reductivelabs.com/projects/puppet/documentation/typedocs.html#resources),
I assume that users can be purged.
However, when I attempt to do this with resources { user: purge => true,
noop => true } and what I get is:
err: Found a bug: private method ''split'' called for nil:NilClass.
