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". -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Is there a way to use validates_numericality_of and still allow null values? I have a model with some optional values that can be nil, but if they''re present, they must be numbers. Will I need to construct a custom valiation for this, or is there some method built in? Seems like it would be a common enough need. Jeff -- Posted via http://www.ruby-forum.com/.

I think I must be doing something wrong... when a form returns params to the controller, empty fields appear to be returned as blank, not nil. so what''s the point of an :allow_nil=>true setting on a validation? it fails because blank is not the same as nil. i would expect either returned empty fields to be nil, or :allow_nil to really be :allow_blank. otherwise i have to do a search through params every time i do a create/update to convert blank to nil. totally unrailsl...

Here''s the issue: When I submit a form for updating, @person.update_attributes doesn''t work. But the next nested clause for updating images DOES work. How is that possible? However no matter what I do the Person object will not change its attributes. def edit @person = Person.find(params[:id]) if request.post? @person.update_attributes(params[:person])

It appears that if your trying to use validates_inclusion_of for a string value allow_nil wont work. For example, if I have an attribute :year which is stored as a varchar then: validates_inclusion_of :year, :in => "1980"..Time.now.year.to_s, allow_nil=>true will successfully validate the range but will not allow an empty input field to be submitted. However, i...

I have a model where initially, they we don''t insert an gov_id value because it isn''t known. The field is given a value of "" because it is on the form. I then added code to the ''create'' method to set that value to nil if it is blank which seems to be fine but then it fails this validation (if NULL) validates_length_of :gov_id, :maximum =>

Please let me know if this breaks protocol. Cheers, Ian White --- patch summary Summary: extra option :allow_nil for composed_of allows nil attributes in aggregations. Currently aggregations do not allow nil attributes. This means that if you want an optional aggregation in your model you must code this into your component class. This is, in most cases, a defect. For example, you may want an optional gps_lo...

How would I use validations to ensure I either received a blank value or a ten digit number? If I set validates_length_of :field, :in => 0..10 then that would allow any value in-between. The allow_nil => true option does not seem to work. I''ve also tried using this with some combination of validates_numericality_of but cannot get it to work. Any help would be greatly appreciated.

I''m using Rails 2.0.2 and I have been trying to take advantage of the "validates_numericality_of" with the ":greater_than" option with something like this: validates_numericality_of :users, :greater_than => 0, :only_integer => true, :allow_nil => true, :message => "The number of allowed users must be a whole number greater than zero." But this doesn''t seem to be catching values set to zero or negative values. Am I using this correctly? NOTE: I have the same problem with the "" option so I assume it i...
