similar to: validates_numericality_of, :allow_nil => true?

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.

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,

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:

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

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

Greetings, Today I''ve been working out how to begin using Capistrano and so far I''m impressed. Even in my situation, learning Rails and deploying to a single server, it''s incredibly helpful. I do have one small question though: In using Subversion I''ve used the "ignore" feature to ignore my local database.yml file, because my local database and

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 =>

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

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

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

Hi all- I just decided to move from my 1.1.0 to 1.1.2. I had previously frozen to 1.1.0 and therefore had all of rails in SVN in my vendor directory. When I finally got rake freeze_gems to work, it blasted (rm -rf) my vendor/rails directory and put a new one in there. This also blasted all my .svn directories. Is there some convenient way to do a freeze upgrade and play well with SVN?
