Hi, I wrote a little helper that calulates someone''s age based on his/her date of birth. def age(dob) diff = Date.today - dob age = (diff / 365.25).floor age.to_s end It works fine, but it''s not completely accurate as it just takes the average days in a year. It should be able to calculate this more accurately, right? I can''t work it out

I want to allow users to enter a day and a month, but not necessarily a year. i.e. it should be optional. If I select the day and month, but a blank year and then submit i get: 1 error(s) on assignment of multiparameter attributes The paramaters regarding the date look like this: {"date_of_birth(2i)"=>"3", "date_of_birth(3i)"=>"17","date_of_birth(1i)"=>""} My select looks like this: <%= date_select ''contact'', ''date_of_birth'', :order => [:day, :month, :year], :include_blank => true...

This plugin gives ActiveRecord the ability to do stricter date checking. Example: class Person < ActiveRecord::Base validates_date :date_of_birth end This will ensure that date_of_birth is a *valid* date. The date can be set initially as a string in any of the following formats: "2006-01-01" "1 Jan 06", or "1 Jan 2006" "1/1/06" # Day / Month / Year They will all be parsed into a date object...

I''m using the date_select form helper for a date_of_birth field on an ActiveRecord object. When I try to save a date earlier than 1 Jan 1970, ActionController punts with ActiveRecord::MultiparameterAssignmentErrors. The message it gives is "1 error(s) on assignment of multiparameter attributes". I was able to catch the exception and look at i...

I have a callback (before_save) that I want to trigger only when certain fields within a record have changed. For example given a user record with ''username'', ''password'' and ''date_of_birth'' I would like the callback to do something only when the ''username'' or ''password'' changes or when the ''date_of_birth'' changes from nil to something real. For example, how would I write... before_save :audit_changes def audit_changes...

I have an application that requires users to be in a specific age group, or above a certain age. For simplicity sake lets say they have to be at least 18. This is my most recent attempt to produce the desired result: validates_exclusion_of :birthday, :in => Range.new(Date.today, Date.parse( (18.years.ago).strftime(''%Y/%m/%d'') )), :message => "does not meet

Can somebody tell me why the following RegExp doesn''t work for date validation in Rails... It validates fine in RadRails -- using REgExp panel. Intended format: (mm/dd/yyyy): %r{^(0[1-9]|1[012])(-|/)(0[1-9]|[12][0-9]|3[01])(-|/)(19|20)([0-9][0-9])$} If i try the following, it works in Rails: %r{(0[1-9]|1[012])(-|/)(0[1-9]|[12][0-9]|3[01])} When I add the last piece, it

...ers three selection boxes, year, month and day. But I want order as day, month and year. I added :order option for datetime_select, it renders normal selection boxes with order year, month and day. Why :order does not work with datetime_select? see my following code <%= datetime_select(:user2, :date_of_birth, :discard_hour => true, :start_year => 2000, :end_year => 1910, :order => [:day, :month, :year])...

Hi, I have this helper and would like to add a html class to each of the select box''s it generates, however I have been unable to find a way? <%= f.date_select ''date_of_birth'', :order => [:day,:month,:year], :start_year => 1940, :end_year => Time.now.year, :include_blank => true %> Any suggestions? thanks john -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you...

In a Rails controller I set the scope on a model class in an around filter. I have defined expectations on the model classes, and ideally, I would add a further expectation for the scope. Is this already possible in some way? How would I go about adding support a scope expectation? Michael -- Michael Schuerig mailto:michael at schuerig.de http://www.schuerig.de/michael/
