similar to: Validation of params

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, 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 have been looking at the many validates_* methods that we have available and I am wondering is it possible to create a custom validation method to be performed on a form field? I have the following form (remote via ajax) <%= form_remote_tag :url => { :action => ''do_action'', :id => @pid }, :before =>

Hello everyone, I''m almost cracking my head trying to do this birthdate validation.

I''ve been working with the problem that Joe Hosteny has been talking about on this list and on the tickets he''s posted (http://dev.rubyonrails.com/ticket/1196) and have come up with a tentative solution that I''d like to bring up here. What if we use a "conditional" parameter in the validates_* methods? Here''s how it would look like in practice:

Hi! I have an error that I don''t understand. It shouldn''t be happening, according to the documentation!

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 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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, A few months ago someone posted a message about specifying validates_* constraints on a per-attribute basis. I just created a small plugin that allows you to do this. Here''s an example from one of my models: class Country < ActiveRecord::Base attribute :name, :string do |a| a.validates_length :within =>

Hi all, I have this problem with lattice that xyplot() won't draw some of my axis labels if the type (i.e. the relation argument) of scales is set as free. For example, in the plot below, I would want it to also show: 1. the labels E1,...E6 below the 10th panel (i.e. 3rd row, 2 col)....just as it is now done below the 12th panel.... 2. as well as the labels (2,4,6,8) on the top of panels 1

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 having difficulty understanding how to make validation of facade columns consistent with validation of other active record columns. To illustrate this, I''m going to extend the facade column example discussed on pp. 284-5 of AWDR. Let''s say that there is a "rectangles" table that has width and height columns. For some unknown reason, width is stored in

Hi there, I have some model classes where I''ve tested successful that validation worked. After some more days of iterations I found that that validation isn''t working anymore. The validation functions are not even called. Example: class Company < ActiveRecord::Base validates_uniqueness_of :name validates_numericality_of :money validates_each :money do |record, attr,

I would like to validate a model on several events. I have: validates_numericality_of :ships_in, :on => :update, :message => ''xyz....'' I have this validating on update, but I also want it to validate on save and on create as well. Do I have to duplicate this validator for each event? or is there something cool i can do like: :on => [:update, :save, :create] (which
