children of objects are not instantiated?
Hello,
I''m a Java developer and I''m looking at Rails as a very interesting thing.
I read the article
http://theserverside.com/articles/article.tss?l=RailsHibernate
and saw a couple of things that I didn''t like too much:
1) The N+1 problem
This has been discussed in the thread (or should I say "flame"?) "Java
people want to beat us". It seems

ActiveRecord & Prepared Statement
I searched the archives and found a thread about it, but I didn''t
understand: are prepared statement used by ActiveRecord on those
databases that could handle them (Postgresql, Mysql, Oracle etc)?
In case they are not used, are they planned? Is there a roadmap about
Rails I can find somewhere?

update_attrbutes without saving?
Hello all,
Is there a method for updating all the attributes from a hash without
saving to the database? (the counterpart of update_attributes but
without saving).
What I want to do is:
person = Person.find(params[:id])
person.update_without_saving(params[:person]) #update the in-memory
object.
# Process person object
.......
person.save
I know that when you are creating a new object, you can

(short notice) Cambridge LLVM Social tomorrow (Wednesday)
Hello various people,
A few LLVM folk are in town for the ARM researchers gathering towards the end of the week and we discussed briefly the idea of having a small pub outing for them this week.
It looks as if Wednesday is the best day, so let’s aim to go back to the Fort St George[1]. The weather is supposed to be warm again this week (though I’m sure Renato will strive to organise rain for

transactions with two models
Hi,
In Agile Web Development with Rails section on Transactions (p 381)
there are two main examples.
1) making changes in two records in the same database table
2) making changes in two records each in a different *database*
I want to do what is in between: changes in two records each in a
different table of the same database. Suppose they are apples and
oranges tables.
How do I write this?

@model.update_attributes(params[:model]) without saving?
Is it possible to update the parameters from a form without saving?
@model.update_attributes(params[:model]) will save the model after
updating its attributes. I''d just like the attributes updating without
a save.
Thanks
Chris

"has_and_belongs_to_many" (habtm) relationship using a join table. The
join
table has an a few additional columns besides the _id columns.
For those of you with the Agile Web Dev w/ Rails book, it''s exactly the
same
setup as the articles<->articles_users<->users example on p240.

update_attributes and save!
I notice that ActiveRecord::Base.update_attributes() calls save().
What if I want to get an exception if the save fails? Is there a way to
get the update_attributes() function plus the save! function?
Thanks,
Wes

@user = user
@company = user.company

User.transaction do
@user.update_attributes!(params[:user])
@company.update_attributes!(params[:company])

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:

I get the error:

specing rescue, ensure and else blocks of an Exception
Greetings,
I''m using rspec with rcov for my applications and there is one issue
which I cannot solve nor can find any proper information regarding
it: specing what is in a rescue block in case of an exception.
I''m using Ruby on Rails and I usually make use of exceptions in my
controllers, like the following example:

update_Attributes stale Object error
Hi,
IN one of my unit tests I get an ActiveRecord::StaleObjectError:
Attempted to update a stale object
object.save!
in object I have apart from other stuff an after_save method, which
calls
object.assosication.update_attributes(...)
If I remove that line from my code my tests succeeds.
Unfortunetly, I do not understand why an update_attributes call can
generate an StaleObjectError.

model with not te be updated attributes ?
Hi List,
I have a table that contains several fields that must be initialized
when first created, but may not be altered afterwards (when updating the
other fields) because they can be changed by external processes.
I noticed that the ActiveRecord update commands (even update_attribute)
only seem to work by loading the complete record, changing fields that
need to be changed and doing a full
