How can I overwrite the parent.children.push(child) Method?
Hi all
I want to overwrite the push method (which is an alias of <<, the same
as concat) of collections, and there I want to test if :uniq is set to
true in the relationship. If so, the method should check if the passed
object is already related to the parent, or not (only then it will be

I''m trying to use ''fields_for'' in a form. I want the same form to
support both the creation of new obejcts as well as the editing of old
ones. So - in my controller, sometimes I will pass to the form an

times I will pass it a newly created instance of an object that does
not yet exist in the database and

Stop updated_at from auto updating?
Hi
Is there any way to temporarily stop the updated_at field from being
updated when a record is modified with ActiveRecord?
I have a date field which is keeping track of when the record data was
last checked by my application and my app manually updates it, of course
when I do this the updated_at field is also touched making it fairly
useless for finding out when the actual data was changed

AJAX form inside table - error
Hello,
I need to put an AJAX, form such that it is inside a table, and spans across
few rows.
But, what I am noticing is that, while submitting the form, the data in the
fields is not submitted.
If I move the form outside the table or inside a cell, things work OK, but not

Authentication: is a guest a user or an "exception"?

I''m currently implementing authentication/authorization in my app. Now
I''m wondering what''s the common way to handle a guest...
In fact, many of the visitors of my app will be anonymous users that
just want to read articles etc., but one can register as a member to
have some further possibilities. So far one can login as a member and
