How do you detect if ''update'' save fails?
So I''m updating multiple model objects in one go with something like
this in my controller:
=> Photo.update(params[:photo].keys, params[:photo].values)
When the update fails due to validation errors, how do I detect it?
The Rails API says:
"If the save fails under validations, the unsaved object is still
returned."
So I can''t simply do this:

Change Password with acts_as_authenticated
I want to have a form to change a users password. I can''t figure out
what the method in the controller should look like. I tried @user.save
and @user.update_attributes, but can''t get it to work.
My Form:

attachment_fu thumbnails
howdy!
I had the problem that attachment_fu didn''t make a thumbnail, but
everything else worked. I read this post
http://www.ruby-forum.com/topic/104213 and added a parent_id column. now
I get the following error when I trie to add a photo:

Activerecord equivalent of the SQL "SUM()" function.
Search doesn''t seem to be working, so forgive me if I''m covering old
ground here, but I''m having a difficult time figuring out how to
implement a "SUM()" function using Active record. Obviously, I could
just create a query, but I''d rather make it part of my active record
object.
Basically I have an object called "Report <

update_attribute with Validation?
Does anyone know of a way to update individual attributes with
validation? update_attribute disables the validation checks in the
record model, so I''m wondering if there''s a workaround for this.
In my application, I want to allow the user to update some or all the
attributes without having to enter :password and :password_confirmation,
both of which are subject to

update_attribute and validations
Just in case it saves someone else the several hours of insanity I just
went through, update_attributes will not save unless the model
validations are satisfied, but update_attribute (the singular form)
will save the attribute to the database even if the model validations
would fail!
This appears to be a feature, not a bug

nested attributes question
Hi,
I have a product that has many photos, so when creating a new product
the user can upload as many photos as they want. This all works fine
using nested attributes for. I want the user to be able to set one of
the photos as the default/primary photo, so i have played around with
using a radio button to decide which photo to select as the default
but i cant seem to figure out how to save this

validations.rb of ActiveRecord - bug or misunderstanding?
Either I''m not understanding how things are used, or this might be a bug
in ActiveRecord. I''m using version 1.13.2.

trunk version is browsable at

execution timeout
Hi!
I have a rails action controller method which takes long time to
complete.
After about 4-5 minutes running, I get a "execution expired" error which
stops this method''s execution.
I looked and looked, searched and searched, but could not find how to
configure my ActionController''s timeout to be greater than the default.
Could anyone help?

ActiveRecord::RecordNotSaved - bizarre behaviour.
Hi. I get a RecordNotSaved exception when trying to create a user record.
The error:

As you can see, there''s no INSERT SQL generated, which is the root cause
of the problem.

STI, subclasses and callbacks
I have a STI class tree. I want to set some default values (calculated
values so I can''t set it in the database as defaults) on every created
instance regardless of what subclass is actually instantiated. So I
figured adding a after_create callback in the top class in the hierarchy
should do the trick. It seems it doesn''t get called :(

acts_as_paranoid overrides ActiveRecord::Base??
Guys,
I am trying to figure out what exactly does this line do at the end of

My problem: I have some classes that I use acts_as_paranoid, and others
with tagging support. Classes declared as taggable, throw error, which

attachment_fu & update_attributes... bug?
It seems that attachment_fu is a pretty popular plugin (it''s great), but
I''ve been having a terrible time trying to figure out an issue when

It seems that when "update_attributes" is called with a new file,

Are cache sweepers used?
After drawing many virtual blank stares in the IRC channel and finding
zero results on the wiki for ''sweeper'' I''m left to wonder whether
these are actually officially supported, or are on their way toward
being deprecated. Is there a better way of expiring caches on model
saves and deletions?
