Combine 3 select fields and validate as one in my User model in ruby on rails 3
- by Psychonetics
Ok I have 3 select boxes for selecting date of birth.
I have constants setup in my User model to provide months, years etc..
Anyway I can successfully validate these select boxes separately.
What I want to do is combine the :day, :month and :year and store in :birthday and validate the whole date as one so I can return 1 error rather than 3 separate ones.
Also doing this will make it easier to store the validated date in my birthday field in my database.
Part of my form
<td> <%= f.input :day, :required => false, :label => "Birthday: " , :prompt => "Day", :collection => User::DAYS %></td>
<td> <%= f.input :month, :label => false, :prompt => "Month", :collection => User::MONTHS %> </td>
<td> <%= f.input :year, :label => false, :prompt => "Year", :collection => User::YEAR_RANGE %> </td>
Part of User model
MONTHS = ["January", 1], ["February",
2], ["March", 3], ["April", 4],
["May", 5], ["June", 6], ["July", 7],
["August", 8], ["September", 9],
["October", 10], ["November", 11],
["December", 12] # finish this DAYS =
1..31 # finish this START_YEAR = Time.now.year - 106 END_YEAR =
Time.now.year YEAR_RANGE =
START_YEAR..END_YEAR
class User < ActiveRecord::Base
attr_accessor :day, :month, :year
validates_presence_of :day, :message
= 'What day in a month was you born?'
validates_presence_of :month, :message
= 'What month was you born?'
validates_presence_of :year, :message
= 'What is your year of birth?'
end
