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:

Hi, there. I have two validations in the model: validates_numericality_of :value, :only_integer=>true, :allow_blank=>true validates_size_of :value, :is=>9, :message=>"must be 5-digit number", :if=>Proc.new{|u| u.value.is_a?(Numeric)} They work as expected except when the :value is character/string like "a" "abc", the second validation will also output

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

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:

Hi I''ve got a problem validating a boolean and I can''t see what the problem is. Here''s my model: class FinanceAgreement < ActiveRecord::Base belongs_to :asset validates_presence_of :finance_company validates_inclusion_of :balance, :in => 0.01..10_000_000 validates_inclusion_of :term, :in => 1..600 validates_numericality_of

Hi all - To avoid floating point issues, I''ve decided to store monetary values in cents in the database. However, the user will enter these in dollars and cents. Two questions: 1) How do I do the validation for the currency format? It looks like ActiveRecord truncates the cents since it thinks the field type is a Fixnum. Am I forced to do validation in the controller? 2) Where

Hi, I have some problems with an application where I''m using custom accessors to do currency conversions. In my model, I have a price attribute in the database that stores the value in cents, to avoid future problems with float arithmetic and round. But at the views, I would like to show the price in euros, with decimal for the cents. So I defined a new attribute called price_in_euros,

I''m having a problem, ''cause I wrote the following line in my model "Hi": [code] validates_numericality_of :phone, :only_integer => true, :allow_blank => false, :message => "must be a number" [/code] And in my "new" view, I put: [code] <%= error_messages_for :oi, :header_message => "Erro ao cadastrar

hi there, I am about to embark on a mission critical financial web application, and was wondering weather ruby on rails is the best fit for this type of project. More specifically I am worried about floating point errors. Would it be more appropriate to use a more statically typed framework (.NET)? thankyou. -- Posted via http://www.ruby-forum.com/.

I have a rather complex object with a number of attributes. For a variety of reasons, I would like one view to create the object with only a couple of fields completed, then a second and third view to finish all the fields. I would like the model to validate_presence_of all these fields, since eventually I need them all there, and I would like each page to validate its portion of the fields that

If there is an error it will also return to the same page with the appropriate error messages. I want it to be able to 1. Carry over all the values on the form fields 2. Use the rails validation methods How can I acheive

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 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
