similar to: date (age) validation

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 /

i know it''s probably really simple, how do i work out someone''s age if i have their d.o.b. stored as a date in my db. cheers -- Posted via http://www.ruby-forum.com/.

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

Can''t get this?...I''m close I think, my calculation appears to be working, but.... when i access duration = <%= @enquiry.course_duration %><br> in my final view it''s blank.. course_duration is getting set to null but works for the calculation? controller.. ---------- class EnquiriesController < ApplicationController layout ''welcome''

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 it, and it is certainly complaining

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",

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

when retreiving a date from a DATETIME field in a database, is there a way to set the date to the value of the DB in the view? It seems to always default to the current date... if I have a field called birthdate in the users table and i do @user = User.find(@params[:id]) in my view i have a <%= date_select ''birthdate'',''user'' %> but dont know how to

Hi, Does anyone know of a method to validate a DateTime field? I''ve looked at the validation docs and the validates_date / validates_time plug-in but I can''t find a method to validate a value in the format of yyyymmddhhmm. It seems like something that should exist already, so I''d just like to check before I attempt my own version... Cheers, Mark

Hi, I have this rails query: @birthdays = Birthday.find :all, :conditions => ["user_id = ? and birthdate = ''2006-02-01'', @user_id], :limit => @birthday_pages.items_per_page, :offset => @birthday_pages.current.offset You can ignore the user_id, limit and offset part.

I want my date fields to default to NIL or "", because the presence of a date means something. My problem is that rails is defaulting the fields to today''s date automatically when I create a new record through the scaffold. I tried removing the default ''0000-00-00'' and changing NOT NULL to NULL, but both columns get today''s date as the default

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

Dear RUsers, I guess this is an easy question for someone a little familiar with programming...(which I am not)... I've got 2 colummns, one shows just dates(SST_date, Class 'Date' num), the other one shows the SeaSurfaceTemperature (SST, num) at that certain date. SST_date SST 2008-01-01 22.2 2008-01-02 21.8 2008-01-03 22.8 2008-01-04 22.9 2008-01-05 23.1 2008-01-06 23.2 ...

I am using date_select and in some instances it only shows about 10 years worth of choices. Same form on other users shows the whole range. date_select looks like this <%= date_select ''user'',''birthdate'' , :start_year => 1940 %> I would expect to always see 1940-2006 or so , but i dont always do. Is there a way to force the range or explain why i

As an R beginner, I feel brain dead today as I can not find the answer to a relatively simple question. Given a array of string values, for example lets say "mary", "bob", "danny", "sue", and "jane". I am trying to determine how to perform a logical test to determine if a variable is an exact match for one of the string values in the array
