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

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...

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 and add an appropriate error message. Is there an easier w...

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'&...

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...

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: ------------------------------------------- purchase = Purchase.new purchase.some_number = ''This is not a number'' Right now the data is not correct. Is this ok? Why should I ev...

It seems that the validations for: greater_than greater_than_or_equal_to less_than less_than_or_equal_to equal_to odd even Simply do not work (Rails 2.0.2). I''ve tried every combination I can think of and these never seem to fire. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails:

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 !an_object[n].blank?) While testing, Rails validation can catch -0.003. However, it just does not catch -.003 (without leading zero). In fact, in case...
