How to set default selected value for Rails SimpleForm select box

问题

I'm trying to figure out how to set the selected option of a select box generated by SimpleForm. My code is along the lines of:

<%= simple_form_for(@user) do |f| %>
  <%= f.association :store, default: 1 %>

Of course the default: 1 part does not work.

TIA

You can now use the following:
