thread_pooling sleeping
I''m trying to run a single worker that could perform a periodic task
for a given user.

:data => { :user_id = current_user.id })
end

Possible to use attr_reader/writer in model?
I have some properties that I want setable externally, but readable only
internally. I''ve played around with attr_writer (and attr_reader
separately) but can''t figure out how to get either to work. I can do
what I want using attr_accessor, or just straight out defining the prop
setter method. Anybody know how to use attr_writer or attr_reader with a
model?
You da man,

find_all_by deprecated?
Is find_all_by deprecated and/or find_first_by for 2.0.2? If not,
what is actually deprecated? just find_all(..) and find_first()?
Thanks for clearing this up.

Problem with yum on CentOS Linux release 7.2.1511 (Core) with 3.10.0-327.36.3.el7.x86_64 kernel
Everyone,
I am at a loss on this problem would appreciate some guidance as to
where to start to fix it.
I noticed that my home gateway server was not being updated with the
new kernel and other software, and when I ran yum it aborted with the
following notices. I tried a yum clean all, but this did not fix the
problem. I thought the problem may be related to one of the repos, but

Self-referential join model does not work
I have been trying to model a labeled graph using ActiveRecord (trunk
version). Basically, I have a ''Node'' model which represents a node linking
to other nodes. Links (aka edges) are labeled (i.e., have a ''label''
attribute and other behavior). Thus I decided to model edges as an ''Edge''
model and use a ''has_many :trough''

find(:all) vs find_all
I started with Ruby on Rails in the 0.13.x period, so I''m sure I
missed out on a lot of history. There''s probably some good
explanation for something I''ve been wondering about, but I haven''t
seen it written down anywhere. Maybe someone can clue me in.
I''ve always felt that one of the uglier APIs was the
ActiveRecord::find() method. I call

file_column do download from URL
Is there a simple way of forcing file_column to download file from given

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:
"undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from
ActiveRecord::Base inherited class.
Code:
class EinsatzFilter

Validation question
Hi all,
I have something like this :
user has_many lists
list has_many items
I want to validate that the currently logged-in user is the owner of the list
an item is being added to. I can do it in "item/create" by doing something like :
class item
def create
@list = List.new( @params[ "list" ][ "id" ] )
if @session[ "user"

Does text_field go directly to attributes hash in AR object?
All,
I''m having a hell of a time figuring out what is going on here.
I''m trying to override one of my getters so that I can format it a
certain way in my form. But I can''t seem to get text_field to call the
appropriate method on my object.
So here''s my getter:

attr_reader, attr_writer, attr_accessor, etc... and have no idea what

2 belongs_to to the same parent table
Hello!
I have 2 table: users and buddies
User: id, name, ...
Buddy: id, user_id, user_buddy_id, ...

Should counter_cache fields be saved in the database?
As far as I can tell, the counter_cache option on a belongs_to model
doesn''t actually save anything in the database. For example, I have
the following models:
class Parent < ActiveRecord::Base
has_many :children,
:conditions => "deleted_at IS NULL"
end
class Child < ActiveRecord::Base
belongs_to :parent, :counter_cache => true
end
With the following
