I'm getting in filterrific, and find it really good for its integration with draper decorators and so.
But I would like to make a simple request with a scope without parameter.
Imagine a model scope like scope :unassigned, -> { where(support_user: nil)}
. Then you can do Ticket.unassigned
to perform the query.
How do I integrate this unparametred scope with filterrific? With an "unassigned" check box for example.
EDIT: The 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 that we miss is filter with enums. If I have
class Ticket < ActiveRecord::Base
enum status: [:wait, :closed, :deleted]
...
end
And want to make a filter that call Ticket.wait
, how would it be possible?
Thank you!
Use a checkbox like so:
<%= f.check_box "unassigned", class: 'filterrific-periodically-observed' %>
Make sure that the unassigned
scope exists and is added to the filterrific
directive in your model.
Then pass the argument to your scope and check for the value:
scope :unassigned, ->(yes_or_no) {
return nil if '0' == yes_or_no
where(support_user: nil)
}
I've adapted filterrific in a way it can afford scope with arity 0 and enum requests. As arity doesn't reveal correctly the number of necessary arguments I use ArgumentError exception. Hello! I had the same expect for fiterrific. I've made a fork. As arity for scope and enums doesn't work as expected I use 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
