Rails options for select send nil when no option selected

I have the following code in my rails app:

<%= select :object,
           :id,
           options_for_select(Hash[@object_list.map { |object| [object.name, object.id] }]),
           {:include_blank => 'Please select...'},
           {} %>

If no option is selected then in my controller I receive an empty string.

How can I make the options for select send 'nil' value instead?

I think you can achieve that by inserting nil in your list.

<%= select :object,
           :id,
           options_for_select(Hash[@object_list.map { |object| [object.name, object.id] }].merge({:0 => nil}), selected: 0) %>

You should use before_action callback for your controller.

class SomeController
  before_action :prepare_params

  private

  def prepare_params
    params[:your_param] = nil if params[:your_param].blank?
  end
end
