ruby on rails - Filterrific, scope without argument and check boxes -

i'm getting in filterrific, , find integration draper decorators , so.

but make simple request scope without parameter.

imagine model scope scope :unassigned, -> { where(support_user: nil)}. can ticket.unassigned perform query.

how integrate unparametred scope filterrific? "unassigned" check box example.

edit: form code:

<%= form_for_filterrific @filterrific |f| %> <%= f.hidden_field( :at_and_under_node_id,class: 'filterrific-periodically-observed') %> <%= f.label "unassigned" %> <%= f.check_box :unassigned, class: 'filterrific-periodically-observed' %> <%= link_to('reset filters',reset_filterrific_url) %>  </div>  <%# add automated spinner form when list refreshed %>  <%= render_filterrific_spinner %> <% end %> 

update: feature miss filter enums. if have

class ticket < activerecord::base   enum status: [:wait, :closed, :deleted]  ... end 

and want make filter call ticket.wait, how possible?

thank you!

use checkbox so:

<%= f.check_box "unassigned", class: 'filterrific-periodically-observed' %> 

make sure unassigned scope exists , added filterrific directive in model.

then pass argument scope , check value:

scope :unassigned, ->(yes_or_no) {   return nil  if '0' == yes_or_no   where(support_user: nil) }
