similar to: calculate age of a person and compare it

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

:D Hi, I installed wine on ubuntu 10.10 to run a windows program as reported here (http://appdb.winehq.org/objectManager.php?sClass=version&iId=22133&iTestingId=59338). After few trails I decided to reinstall Wine (now version 1.3.8 ), to configure it as instructed by the guide, and than to install again the windows application, Birthday Reminder. At present the application doesn't

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.

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

For some reason I can''t figure out why I am getting a routing error when I add Paperclip support. I have another test app when similar code is working. I created a new test app first without Paperclip support and it was doing the CRUD operation fine. However when I added Paperclip support I get the following error? Routing Error user_url failed to generate from

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 ...

Hi, I have a column of DOB in mm/dd/yyyy. I want to convert this format to age. Thanks a lot.   Best,Farnoosh Sheikhi [[alternative HTML version deleted]]

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

Hi, I''m creating a date type field to put birthdate, but the years on this field only go to 2003, what should I do?? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

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

This isn''t even close to ready for release, but in case anybody is interested, has feedback, finds it useful as is, or even wants to collaborate... I''ve been working on a "personal information server", something of a protocol multiplexer. Right now it serves calendar feeds for: - a local calendar folder (iCal 1.x''s Library/Calendars) - rss for local todos

:) Hi experts, hi dimesio Few days ago Wine/Birthday Reminders stopped to run. I suppose that it is a consequence of an automatic updating of Ubuntu and I ask an advice on the best way to solve the issue. Consider that: if I run the application clicking on it, as usual, I see the system working and stopping after tens of seconds, If I run the application by console, this is the code that I get

I have files which have columns of data that look like this: DOB 9/27/1964 ... That is, dates in month/day/year format. When variables like DOB are read in, they are converted to factors. So, I wrote this to convert from date to age in years: age<-function(x) {as.numeric(Sys.time()-strptime(as.character(x),format="%m/%d/%Y"))/365.25} This isn't very precise or pretty, but it

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

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

Hello everyone, I''m almost cracking my head trying to do this birthdate validation. It turns out that I can only accept users with at least 18 years old and I''m trying to validate it writing this code on my user.rb fil at app/ models class User < ActiveRecord::Base validates_presence_of :full_name validates_presence_of :street_address validates_presence_of :city

Hi, I have a field for the user which is their birthday. I am letting them edit it and then save it if they want. However, the form displays the current date/time, and when they save the form without changing the birthdate (because they do not wish to set it), the current date/time gets saved to the db. How do I do this? I thought about having a hidden field which would be the current date/time

Hello all ! I have a model being validated that spits it''s error messages on the resulting page using: error_messages_for(:mymodel) .... Basic stuff. It''s working perfectly. Now, I have something else I want to check on the same page (that isn''t an attribute to the Model)... and am trying to add it using: @mymodel.errors.add_to_base("another error here")
