Question

I’m having a strange issue where my select options are not remembered on submit (and validations fail, re-loading the form).

Here is my code

<%= form.select :state, options_for_select(us_states), :include_blank => true %>

Here is some of what us_states looks like:

  def us_states
      [
        ['Alabama', 'AL'],
        ['Alaska', 'AK'],

No matter what I select, it always picks to display the blank option in the select box. If I don’t use the :include_blank at all, it always just displays Alabama. So it’s just displaying the first field.

Answer 1

Specify the selected value by passing it as an argument to the options_for_select helper.

<%= form.select :state, options_for_select(us_states, form.object.state), :include_blank => true %>
