Not updating the updated_at field
This is for Rails 3.1.1
I have a field called last_seen in a model. This field will be updated
when the something about the record is seen in the real world (don''t
worry about this part)
So I go x.update_attribute(:last_seen, Time.now) and the following happens is
UPDATE "blah" SET "last_seen" = ''2012-10-23 08:57:46.179288'',
"updated_at"

Saving attribute
Something is getting lost here.
def create
@home = Team.find_by_user_id(current_user.id)
for player in @home.players
player.update_attribute(:game_id, @game.id)
end
end
def show
@players = Player.find_all_by_game_id(params[:id])
end
view
<%= @players.size %> # mistakenly equals zero
Played with the console and everything should be working fine...

Puzzled with form on multiple table rows
I''ve got a table of events, and each event has a boolean attribute
is_ten_event.
On each row of the table is a chekbox to edit the value of is_ten_event,
so that multiple rows can be edited with one submit.
In order to allow boxes to be un-checked as well, the logic in the
controller works like this
get array of events from checkboxes that are ticked.
make all events.is_ten_event =

ActiveRecord::Persistence.increment! requires a row lock to ensure isolated updates
The method is here:
https://github.com/rails/rails/blob/master/activerecord/lib/active_record/persistence.rb#L288.
The method takes the in-memory attribute value and increments it by the
specified amount. A safer approach (from an isolation standpoint) would be
to let the database determine the value. Instead of telling the database
what value to persist in the database, the SQL can written

Why does ActiveRecord allow perception of success when updating an ID, however it doesn't really work(i.e. no change in database)?
Hi,
Why does ActiveRecord allow perception of success when updating an ID,
however it doesn''t really work(i.e. no change in database)?
Here''s an example. The update of "id" versus update of a non-existent
attribute.
?> ai = AccountItem.find(:first) => #<AccountItem id: 1, account_id: 1,
date: "2009-01-11", amount:

Rails 2.3 Model.touch(:column) always also updates :updated_at???
Hi,
Am I the only one (i.e. something I do is wrong), or does the touch-
method always update updated_at, even though giving it a column to use
INSTEAD is meant to update just that column???
Thanks,

Touch an ActiveRecord - timestamps
When I update an ActiveRecord, i would like to "touch" one of the
related objects, that the updated record belongs_to, in order to update
the timestamps on the parent record, although i don''t want to change any
of the data in the parent. Whats the accepted way to do this?

How to determine if an object has just been created
Is there a built-in way to determine if a model object has just been
created (ie. this object was the one that was originally persisted)? I
can''t see it anywhere in the AR code, but thought I''d check. I want
something like:
p = Person.create
p.original_instance? # true
Is this built-in or should I just patch AR?

Newb question about facade columns
Hello,
I am trying to deal with a database table that contains a date in the
form of the number of seconds since epoch. Data is inserted in this
format by an existing script that I can''t change, so a schema change
isn''t realistic.
I would like to allow humans to view and edit this data in the form of
an actual human-readable date. I figured a facade column would be the

update_attributes! does not update nested model
Hi!
I have updated my app to rails 2.3. I have form that has few nested
models and I am happy that I can just write
accepts_nested_attributes_for :tasks, :allow_destroy => true, but
update_attributes! does not update my nested model. I have tried
update_attributes, and it works. Any ideas?
Few lines from log:

[PATCH] Add :touch option to has_many associations
Hi,
it would be nice to have the touch option in has_many associations also.
I have a scenario like this:
An user has some credit (money) and some advertises. Each advertise can be
enabled or disabled depending on some rules. One of the rules is that the
user should have money. Each time the money of the user change, the
advertises are touched, enabled/disabled and then cached, as they are much

Updating only one field
At present, I use an update like this to set the user''s last login time:
authenticated_user.update_attribute(:last_login, Time.now)
However, this calls the following, updating all fields:
UPDATE users SET `last_login` = ''2006-05-02 13:27:41'', `hashed_password`
= ....
Is there any way I can tell ActionRecord to only update the one field?
