similar to: validates_numericality_of with greater_than* less_than* simply don't work

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

Hi, I am trying to validate a numeric value passed in from a form, which is saved in a MySQL db as decimal(9,2) Now problem is I need to ensure people don''t enter a form value like -. 003. In my validations, I have a validates_numericality_of check being done. Furthermore, in validate method, I have a check using an if statement such as : ((an_object[n].nil? or an_object[n] < 0) and

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 have a situation in which I want to validate a number is not zero. 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. I have not yet been able to find anyone who has discussed this. I did find information about custom validators, so I am now using a custom validator to check the field

Like most people, I''ve got two machines: one for development and one for production. I''ve done everything I can to make sure the ruby/rails environments are the same, but of course they''re not identical (I''ll get into that in a moment).

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
