Saving enum from select in Rails 4.1

by

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:

<select id="wine_color" name="wine[color]">
  <option value=""></option>
  <option value="red">red</option>
  <option value="white">white</option>
  <option value="sparkling">sparkling</option>
</select>

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] }
