Does Rails need more useful URL helpers?
Similar topic to my last post, but a different brand of methods. In
particular, the url_for and link_to methods have come to bother me at
times. I will mention one instance in particular:

supports paging, sorting and limiting to specific field values. Thus I
have params named page, sort and limit.
The lack of elegance I see

Store a single variable / row in database
What would be the best way in rails to store a single variable and have
it persist. Like a have a variable that says "total_visits" that counts
the total number of page loads.
The only solution I can think of is having a table with a single row.

after_update attributes problem
Hey guys,
I''m having a hard time w/ the after_update callback on rails... As
far as I can tell, when I define a after_update callback on a model,
the attributes of the object have the same values that they had
*before* Base.save was called. I''m probably wrong so here''s the code:

Reading Model data before update
Hi all,
here is the challenge:
I have this validation method, that basically prevents an object which
billed = true to be updated:
def before_update
if read_attribute(:billed)
errors.add_to_base(''This service has already been billed for'')
end
!read_attribute(:billed)
end
The above code does not work in case I do something like:

How do I stop a column being updated by model.save?
One of my models has a column that is updated very frequently from a
separate process, so it is important that when a record is saved in
rails, this column should be left alone. In the update method of the
controller I have:
@record = MyModel.find(params[:id])
@record.update_attributes(params[:my_model])
params[:my_model] doesn''t have a reference to the column I''m talking

after_update: old, new values?
With after triggers in Postgres, there are special NEW and OLD vars
accessible to trigger functions. Any such thing in Rails? Or would it
entail doing something like setting a class var in before_update?

Jagged ROC curves?
Hi,
I was trying to draw some ROC curves (prediction of case/control status),
but seem to be getting a somewhat jagged plot. Can I do something that
would 'smooth' it somewhat? Most roc curves seem to have many incremental
changes (in x and y directions), but my plot only has 4 or 5 steps even
though there are 22 data points. Should I be doing something differently?
How can I provide a

How do you use :message with validation?
If I do validates_uniqueness_of :name, :message => "It''s not

then how do I have it display that message when the check fails?

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
