Listing user gender options in a view

I am seeking to populate a select list in a form with options for user gender. I have a learning Rails book that uses a similar approach for credit card options by creating an array in the model and then referencing it in the view. Unfortunayely when I use this approach I receive an error referencing the line in my view stating: "uninitialized constant GENDER_OPTIONS"

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable, :confirmable,
         :recoverable, :rememberable, :trackable, :validatable

  GENDER_OPTIONS = { "Male" => :true, "Female" => :false, "Unspecified" => :nil}

  has_many :discussions
  has_many :comments
end


<div>
  <%= f.label :gender %><br />
  <%= f.select :gender, User::GENDER_OPTIONS​ %>
</div>

Try using helper and locale.

# app/helpers/application_helper.rb

def gender_lists 
  I18n.t(:gender_lists).map { |key, value| [ value, key ] } 
end


# config/locale/en.yml

en:
  gender_lists:
      "": Unspecified
      "true": Male
      "false": Female

and on your view, you can do this

<div>
  <%= f.label :gender %><br />
  <%= f.select :gender, gender_lists​ %>
</div>

===

Note :

Just suggestion, user string type data instead of boolean

"sex" should not be stored as a boolean - it is not a true/false value. Aside from labelling half of the people in your database as "false", when you write SQL queries you (and and future developers) will have to know what the magic values are.

And boolean fields should not have three potential states (true/false/nil) - that's just asking for trouble.

To make your database understandable from the schema side, set the field to be a string, and store the values "male", "female", or "unspecified" (or just blank).

Then ask yourself: why on earth do you actually need to ask people about their sex? Unless it's a dating website, or medical DB; otherwise it's just personal info for personal info's sake - you might as well be asking them their shoe size (or any other bodily part).
