Both positive and negative values are acceptable, just not zero. validates_numericality_of has an :equal_to attribute, but I don''t see a :not_equal_to.

Hi, Today someone created a ticket for a defect in validates_numericality_of, at first sight i thought it wasn''t a defect but an enhancement. But then i found that validates_length_of accepts :message => "should be greater than %d", but validates_numericality_of doesn''t (The output for v_n_o is: "should be greater than %d" instead of "should be

Hi, How do I validate a composed_of attribute in my model? I have a product model with: composed_of :price, :class_name => ''Money'', :mapping => %w(cents cents) This maps the price attribute to the Money (http://dist.leetsoft.com/api/money/) class.

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.

I''m having a problem with my User model.

Can anyone enlighten me on how to make in_place_edit fields go through validations that are defined in the model? For example, my customer model has a "validates_numericality_of phone", but when the in_place_edit is done you can enter whatever you want. The field is defined as a string in the DB. I can''t change the database schema, due to other constraints, so I need a

The password_confirmation is there on the screen, but
