Oops. Try again.

Frob.unrestrict_primary_key

Frob.restrict_primary_key
f

Ew...that just won't do. And it maybe restricts when it shouldn't.
module Sequel::Model::ClassMethods
def unrestrict_primary_key
if block_given?
original_value = @restrict_primary_key
@restrict_primary_key = false
result = yield
@restrict_primary_key = original_value
result
else
@restrict_primary_key = false
end
end
end
def create_frob( pk, values )
Frob.unrestrict_primary_key do
Frob[ :id=>pk ] || Frob.new( values.merge :id=>pk )
end
end
Ahhhhh. I think that's much better.
What do you think? (Of the idea, not the exact code.) Like Dir.chdir, it
ensures a particular, necessary set of conditions are met, and then returns the
state to as it was beforehand.
