未在select中设置默认值

Question

任何人都可以看到为什么在这个选择中没有选择“9:00”？

=f.fields_for :hours do |hours_form|
  = hours_form.text_field :start_time # outputs "9:00"

  =hours_form.select :start_time, possible_hours_stop() # outputs a select including one where value="9:00"

不应选择“9:00”，因为它的值是：start_time？

Answer 1

我会试试这个：

=hours_form.select :start_time, options_for_select(possible_hours_stop(), hours_form.object.start_time)
