Best way to nest model validations

Hey everyone,

Whats the best way to nest model validations so multple errors relating
to
the same field appear one by one, rather than all at once? I was talking
with some people on IRC the other day, but two of the ideas I got appear
to
be things that would be nice to have in RoR, but arn’t right now (the
ability to add blocks or if statments, like follows)

validates_presence_of :email do
validates_format_of :email, :with =>
/^[A-Za-z0-9._%±]+@[A-Za-z0-9.-]+.[A-Za-z]{2,4}$/
end

OR

if validates_presence_of :email
validates_format_of :email, :with =>
/^[A-Za-z0-9._%±]+@[A-Za-z0-9.-]+.[A-Za-z]{2,4}$/
end

Neither of these work however, and rather than going into lots of :if =>
and
functions checking if other variables are set and such, I was wondering
if
anyone knew or a gem, plugin, or RoR function to assit with this. Your
help
is much appreciated.

You could overwrite the validate method and manually add errors. Then
you can use simple if then constructs to check the fields.
