Rails f.select with a default value, but a different place holder

I have this bit of code that produces a dropdown menu for me with a default value of Unassigned.

But, what I'd like to do is to have a placeholder, Select Location, on the dropdown menu, although by default the value selected is 'Unassigned'

Code:

= f.select :training_location_id, grouped_options_for_select(grouped_location_options, current_provider.locations.where(name: 'Unassigned').map { |loc| loc.id }), { placeholder: 'Select Location', include_blank: true }, class: 'form-control'

As you can see in the code, I'm setting a placeholder in the f.select { options }, but the dropdown menu still says "Unassigned"

Words of wisdom?

1- Instead of using map to get selected option use find_by or where

 <%=f.select :training_location_id, grouped_options_for_select(grouped_location_options, current_provider.locations.where(name: 'Unassigned').first.id, {:prompt => '-- Select Location --'}),{class: 'form-control'}%>

Or

 <%=f.select :training_location_id, grouped_options_for_select(grouped_location_options, current_provider.locations.find_by(name: 'Unassigned').id, {:prompt => '-- Select Location --'}),{class: 'form-control'}%>

Try this, this might work for you:

= f.select :training_location_id, grouped_options_for_select(grouped_location_options, current_provider.locations.where(name: 'Unassigned').map { |loc| loc.id }), data: { placeholder: 'Select Location' }, class: 'form-control'

try include_blank: 'Select Location'

= f.select :training_location_id, grouped_options_for_select(grouped_location_options, current_provider.locations.where(name: 'Unassigned').map { |loc| loc.id }), include_blank: 'Select Location' , class: 'form-control'
