[Rails] validate_uniqueness_of {combination of fields} ???

I''ve looked at the validates documentation and it appears that
validates_uniqueness_of works on only one field at a time.  So I can, for
example, validate that "sam" is unique to the record set, and that
"smith" is unique to the record set.

My problem is that each record includes two fields, the _combination_ of which
must be unique to the record set, but each of which may not be unique.  So
"sam smith", "mary smith" and "sam jones" (stored
as fname, lname) all need to pass the validation.

Is there an easy way to validate_uniqueness_of a combination of fields within a
record?

Thanks in advance for any help.

Best regards,
Bill

[Rails] validate_uniqueness_of {combination of fields} ???

I''ve realized in rereading my post below that I could have stated the
problem I''m having more clearly.  The system is multi-user, so the
record set within which I''m trying to validate_uniqueness_of is
constrained by a third field (e.g., ''group_id'').  So
I''m already using the "scope" option on
validates_uniqueness_of.  I think what I''m looking for is nested
scoping. Something like:

validates_uniqueness_of :fname, :scope => "lname", :scope =>
"group_id"

Is there an easy (i.e., Rails) way to accomplish this?

Thanks,
Bill

I''ll be damned.  The nested scoping works just the way I wrote it
below.  I''m posting this just so another newbie might be spared the
angst.  RoR ROCKS!

[Rails] validate_uniqueness_of {combination of fields} ???

Oops.  Spoke too soon.  While it doesn''t throw a syntax error. only the
last ":scope => x" option is acted upon.  So the question
remains...

Is there an easy way to accomplish nested scoping?

Thanks much for any advice.

Best regards,
Bill

[Rails] validate_uniqueness_of {combination of fields} ???

Hi Bill,

I think you can achieve what you are after by defining a method like so:

def fullname
  [fname, lname]. join '' ''
end

then validate that:

validates_uniqueness_of :full_name, :scope => "group_id"

That should do it.

Cheers,

Dan

[Rails] validate_uniqueness_of {combination of fields} ???

Hi Dan,

Thanks much for the assist, but it doesn''t work.  That is, the
validate_uniqueness_of fails when AR can''t find a column named
"full_name".
If I''ve missed some nuance of your recommendation (wouldn''t
surprise me to
get a ''hey newbie, of course you have to do X in addition to what I
sent
you''), please set me straight.  At this point, I guess I''m
stuck with having
to go the ugly route.

Thanks much for your response, though.

Best regards,
Bill

[Rails] validate_uniqueness_of {combination of fields} ???

Sorry, yes, that isn''t going to work is it.  I''ll think on it
more.
Shouldn''t try to answer questions at 3 in the morning again.

[Rails] Re: validate_uniqueness_of {combination of fields} ???

Looks like Rails 1.1 has the answer.  From 
http://scottraymond.net/articles/2006/02/28/rails-1.1:

"Allow validate_uniqueness_of to be scoped by multiple columns.  See 
http://dev.rubyonrails.org/ticket/1559"
