Filterrific, scope without arguments and checkboxes
I am getting filtering, and I think it is really good for integrating it with decorators-decorators, etc.
But I would like to make a simple scoped query with no parameters.
Imagine the scale of the model, for example scope :unassigned, -> { where(support_user: nil)}
. Then you can execute Ticket.unassigned
to fulfill the request.
How do I integrate this non-parameterized region with filtering? For example, with an "unassigned" checkbox.
EDIT: Form code:
<%= form_for_filterrific @filterrific do |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 an automated spinner to your form when the list is refreshed %>
<%= render_filterrific_spinner %>
<% end %>
UPDATE: Another feature we missed is the enumerated filter. if I have
class Ticket < ActiveRecord::Base
enum status: [:wait, :closed, :deleted]
...
end
And you want to create a filter that calls Ticket.wait
, how is it possible?
Thank!

I adapted filterrific so that it can create a scope with arity 0 and enum objects. Since arity does not correctly expand on the number of required arguments, I use the ArgumentError exception. Hello! I also expected it to be appropriate. I made a fork. Since arity for scope and enums doesn't work as expected, I am using the ArgumentError exception.
filterrific_available_filters.each do |filter_name|
filter_param = filterrific_param_set.send(filter_name)
next if filter_param.blank? # skip blank filter_params
begin
ar_rel = ar_rel.send(filter_name, filter_param)
rescue ArgumentError #if we have a scope with arity 0 or enum query, we can perform the request without the parameter
ar_rel = ar_rel.send(filter_name) if (filter_param == 1)
end
end
ar_rel
end

Check the box:
<%= f.check_box "unassigned", class: 'filterrific-periodically-observed' %>
Make sure the scope unassigned
exists and is added to the directive filterrific
in your model.
Then pass the argument to your scope and check the value:
scope :unassigned, ->(yes_or_no) {
return nil if '0' == yes_or_no
where(support_user: nil)
}
