In the model I have:
validates :square_meters_public_land, :barrier_meters, :numericality
=> { :greater_than_or_equal_to => 0 }, :allow_nil => true
but if, in the field, on create, I don''t insert a value I have the
error "field is not a number".

I generally think about this in terms of "specifying a validation always includes :required; if that''s not what I want, I have to include :allow_blank". cheers, Bill -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Did it work?... I doubt it anyway, as I had copied your code without checking it, and just added the "if" I''d copied from one of my models. I notice now that you''re not using "validates_numericality_of", you''re using "validates" and seem to be trying to check two values - can''t say that''s an idiom I''m familiar with, but it may be valid (although I can''t see it in the docs: http://ar.rubyonrails.org/classes/ActiveRecord/Validations/ClassMethods.html#M000091) What about: validates_numericality_of :square_meters_public_land, :greater_than_or_equal_to => 0, :allow_nil => true validates_numericality_of :barrier_meters, :greater_than_or_equal_to => 0, :allow_nil => true -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

FWIW, I always tend to think in terms of :allow_blank rather than :allow_nil. Perhaps an artifact of my years in Smalltalk? If :allow_nil isn''t working, as I gather from the posts that appeared before mine (after I posted, but long before mine showed up), have you tried :allow_blank? Does that work better, worse, or no different? regards, Bill -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
