How to skip password validation when updating other fields?
Besides the hashed password, which is saved to db, I have two
password-attributes in my User model:
attr_accessor :password, :password_confirmation
I have validations on these attributes, and I need them to work both on
create and update, since I have pages for changing and resetting the
password.
Now when I want to update just the user''s login name, I guess I have the

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?

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

Unexpected message on :attr_accessor
This may be a dumb noob issue, but I haven''t found any answers while seaching
the forum--
I have a controller method
def edit
@user = User.find params[:id]
@user.password_confirmation = @user.password
end
The User class has an "attr_accessor :password_confirmation" definition (so
"password_confirmation" doesn''t exist in the users table). My spec

Paperclip not executing FFMPEG properly
Im using a customs processor to run ffmpeg on a video to create a
thumbnail.
So far so good. Except when I do:

success = Paperclip.run(''ffmpeg'', cmd)
Console is reporting:

Setting a message on a model -without- errors.add_to_base
I''m trying my best to follow the skinny controller/fat model concept,
and I''ve got a series of callbacks (that I''m about to move into
observers) running on a few models. Based on what these callbacks do
to the data (it''s implementing business rules), I''d like to add some
type of message on the state of the model *without* invalidating it.

How to update partial attributes of a object from a form?
I have a user table, and it has forty columns, including name, gender,
address, email, phone...
So my @user object will have forty attributes.
I divide these attributes into 4 groups... namely ''general info'',
''personal info'', ''contact info''... and I make separate forms to edit
these 4 different group attributes.

How To Spec Controllers with Finders
Given this code (which renders rjs), I''m faced with the fixture-
driven way of spec-ing or mocking. How the heck to you mock this so
the code at line (2) and (4) work right? I''m still struggling with
mocks but it seems like this can be done. Forgive the naivety of this
question.

Updating an attribute in db
Hello
I am a Ruby newbie, thus a rather simple question.
My list view shows table records and enables user to click a button in
order to change value of one attribute in given record. I use this code
to invoke a method from controller:
<%= button_to "Change", { :action => "edit", :id => prog.id_prog } %>
My method looks like this (just a simple one - to set the

Re: Some advice on DB modeling
I have more or less the same problem. I''m trying to build a system where
users can enter their friends. But the solutions seems not to work for me.
I used same sql:

Consequences of overriding update_attribute to force validation?
I know the debate of whether this should validate has been rehashed
many times. My question is, what are the consequences of overriding
this method to force validation? Will this break fundamental things?
Will it break plugins? Is there a reason not to have a strict
validation option?
In my code I will never use this as I consider it a terribly broken
method, but some gems use it and in one case

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
