Saving enum from select in Rails 4.1

Question

I am using the enums in Rails 4.1 to keep track of colors of wine.

Wine.rb

class Wine < ActiveRecord::Base
    enum color: [:red,

Alright, so apparently, you shouldn't send the integer value of the enum to be saved. You should send the text value of the enum.

I changed the input to be the following:

f.input :color, :as => :select, :collection => Wine.colors.keys.to_a

Which generated the following HTML:

  
  red
  white
  sparkling

Values went from "0" to "red" and now we're all set.

If you're using a regular ol' rails text_field it's:

f.select :color, Wine.colors.keys.to_a

If you want to have clean human-readable attributes you can also do:

f.select :color, Wine.colors.keys.map { |w| [w.humanize, w] }
