module Blacklight::Solr
# Pagination for facet values -- works by setting the limit to max
# displayable. You have to ask Solr for limit+1, to get enough
# results to see if 'more' are available'. That is, the all_facet_values
# arg in constructor should be the result of asking solr for limit+1
# values.
# This is a workaround for the fact that Solr itself can't compute
# the total values for a given facet field,
# so we cannot know how many "pages" there are.
#
class FacetPaginator < Blacklight::FacetPaginator
# all_facet_values is a list of facet value objects returned by solr,
# asking solr for n+1 facet values.
# options:
# :limit => number to display per page, or (default) nil. Nil means
# display all with no previous or next.
# :offset => current item offset, default 0
# :sort => 'count' or 'index', solr tokens for facet value sorting, default 'count'.
def initialize(all_facet_values, arguments = {})
super
@sort = arguments[:sort].keys.first.to_s if arguments[:sort].is_a? Hash
# count is solr's default
@sort ||= if @limit.to_i > 0
'count'
else
'index'
