Set the default value for date_range in rails 4

Question

如何在Rails 4中设置默认值？

filter :by_resolved_at_in, as: :date_range,label: "Filtro Resolvido em", :value => Time.now.strftime('%Y-%m-%d')

This is ActiveAdmin , right?

You can't do this in the filter line but you can define a before_filter where the ransack values are initialized.

  before_filter :only => [:index] do
    if params['commit'].blank?
       params['q'] = {by_resolved_at_in: Date.today..Date.today} 
    end
  end
