update_all not changing updated_at
Hi everyone-
Model.update_all works and changes the records, but it''s not changing
the updated_at field. Am I doing something wrong or is this by
design?
Thanks,
Dino

update_all Not Incrementing lock_version
Shouldn''t update_all be updating lock_version? As you can see from my
console session below, it is upating the record (changed running
attribute to true and returned 1 to show 1 recored was updated). But it
did not increment lock_version. And optimistic locking is working
correctly otherwise. As you can see below, lock version = 562 before
and after the update_all call but it is

how can I control when to commit a transaction?
hello
it seems like this question has appeared a few times with no answer:
how do you get rails to issue ''write'' statements (ie ''CREATE/UPDATE'') to
the database without committing each time?
I tried setting
ActiveRecord::Base.connection.begin_db_transaction
before calling any action on my object, but as soon as
myObject.save
or
myObject.update
is called,

save without commit ?
How do I get ''save'' to execute without commit?
I have tried:
ActiveRecord::Base.connection.begin_db_transaction
# do some stuff that doesn''t issue a database COMMIT statement

@myObject.save

called:
ActiveRecord::Base.connection.commit_db_transaction

ActiveRecord::Base#update_all expected behaviour
Hi
I noticed that if in my code I use the following:
Photo.update_all("title = ''Ruby rocks'' ", "id IN (#{@photo_ids})")
All my objects are properly updated but none of the filters/callbacks
are triggered. Is that what''s expected?
I have a before_update filter set on the Photo class and it gets
totally ignored, I guess the only way to solve this

ActiveRecord::Observer, update_all and has_many
Hi,
I''m using an ActiveRecord::Observer to log users changing data in my
application. However, I''ve noted that adding an item to a has_many
relationship gets logged, but removing the item does not. That is:
@product.users << user
is logged, but:
@product.users.delete(user)
is not.
I''ve dug into ActiveRecord and found that the underlying issue is that

update_all for an AR instance
Is there anyway to call "update_attributes" where it updates only the
attributes you specify with the update command.
The only thing close to this is update_all where you have to specify the
condition. So essentially you''d be stuck doing "id=#{obj.id}" as the
condition.
Are there any built in AR functions that allow you to update a
particular object using straight

Active Record Basics - Making it commentable

basics? I''ve been banging my head for the past 4 hours and I can''t seem

Reduce Number of Queries When Using ActiveRecord
I have a controller method called update_all that grabs parameters for about
30 form fields and saves them to the database. My current code looks to see
if there is a string in params[] for each form field (two fields for each
SelfEvaluationItem) and saves the updated self_evaluation_answer if a string
is available. Since this is iterated code, I am almost certain that this
generates 30 or so

Field names in validators
Hi!
Is there a (simple) way to use alternative field names in validation
messages? For example, if I have a validator like this one:
validates_presence_of :email
how can I make it print a message like "E-Mail Address can''t be blank"
instead of "Email can''t be blank"? I can override the "can''t be blank"
part by using the :message
