similar to: validates_date plugin for ActiveRecord

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

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

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

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''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 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

Can somebody tell me why the following RegExp doesn''t work for date validation in Rails... It validates fine in RadRails -- using REgExp panel.

Hi All In my project I am to take date of birth from user so I used datetime_select. It renders 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,

Hey All, Anyone know of a library for parsing "human" dates, like "this friday" or "2 days ago"? I used to use strtotime in php, but starting from here; http://wiki.rubyonrails.com/rails/pages/PhpStrtotime and doing lots of googling, I haven''t been able to find anything similar for ruby.
