Blacklight pagination for prev next document doesn't work as lacks a search_session? #94
Description
https://github.com/vecnet/dl-discovery/blob/qa-deploy/app/views/catalog/show.html.erb
Should render a partial previous_and_next_doc for pagination to previous next and back to search. It seems to not work currently as
<% if @previous_document || @next_document %>
don't exist until the Blacklight lib search_context.rb makes them as it contains the function setup_next_and_previous_documents
# calls setup_previous_document then setup_next_document.
# used in the show action for single view pagination.
def setup_next_and_previous_documents
if search_session['counter'] and current_search_session
index = search_session['counter'].to_i - 1
response, documents = get_previous_and_next_documents_for_search index, current_search_session.query_params.with_indifferent_access
search_session['total'] = response.total
@search_context_response = response
@previous_document = documents.first
@next_document = documents.last
end
rescue Blacklight::Exceptions::InvalidRequest => e
logger.warn "Unable to setup next and previous documents: #{e}"
end
That code should already be running as part of the show method in catalog.rb
# get a single document from the index
# to add responses for formats other than html or json see _Blacklight::Document::Export_
def show
@response, @document = fetch params[:id]
respond_to do |format|
format.html { setup_next_and_previous_documents }
Just in case I included it in the controller manually but no dice, still no @previous_document etc.
@dbrower Any ideas?
