similar to: Validating numericality based on related attribute value?

All, I have a field that I''m validating with validates_numericality_of on as well as validates_inclusion_of, like so: validates_numericality_of :number_of_owners, :only_integer => true, :message => ''must be a whole number'' validates_inclusion_of :number_of_owners, :in => 1..3,

I would like to validate a number within a certain range. To first test that a entry is a valid number i use validates_numericality_of :my_number, :message =>''sorry, not a number'' to test if the number is within a certain range i use validates_inclusion of :my_number, :in => min..max, message => ''outside range!'' If the numericality test fails, I

Hi, What is the simplest way to validate a positive integer? validates_numericality_of :foo, :integer_only => true how do I add the positive part? Do I need another validation statement for pattern matching or do I have to write a validate() funciton for my model? Thanks, Peter

First of all, thanks for you time. I have kind of a tricky question and wanted to see what you guys thought. ------------------------------------------- Lets say I have this: ------------------------------------------- class Purchase < ActiveRecord::Base validates_numericality_of :some_number, :only_integer => true end ------------------------------------------- Then I do this:

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

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''ve put together another plugin, this time it adds some convenience functions to the validates_numericality_of validation routine. Nothing in this plugin can''t be done with existing validation routines, it just moves them to a place I feel is more appropriate. http://www.railtie.net/articles/2006/01/27/defining-numericality PS: Sorry for hijacking threads with my

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.

Hello, Have a question related scope definition.

Hi all, In response to Rodrigo Rosas''s message about mb_chars.upcase not giving the expected result on 1.9, I''ve done some work in a fork to make String#mb_chars always return an instance of a proxy class, both with Ruby 1.8 and Ruby 1.9. The end result of the patch is (hopefully) to make Rails'' multibyte functionality behave the same way in 1.8.7 and 1.9.x.

As far as I can tell "numericality" is not a word. Maybe this method should be renamed. -- R. Mark Volkmann Partner, Object Computing, Inc.
