Exception in clean_end_punctuation

[hectorcorrea]

Method clean_end_punctuation in marc_export.rb throws an exception if the value passed is nil

blacklight-marc/app/models/concerns/blacklight/solr/document/marc_export.rb

Lines 493 to 498 in db85fe3

	def clean_end_punctuation(text)
	if [".",",",":",";","/"].include? text[-1,1]
	return text[0,text.length-1]
	end
	text
	end

This is a problem when chicago_citation(marc) is called with a nil value for marc["502"]["d"]. This is the block that makes the call to clean_end_punctuation with nil

blacklight-marc/app/models/concerns/blacklight/solr/document/marc_export.rb

Lines 303 to 305 in db85fe3

	elsif marc["502"] and (marc["502"]["b"] or marc["502"]["c"] or marc["502"]["d"]) #sometimes the dissertation note is encoded in pieces in the $b $c and $d sub fields instead of lumped into the $a
	pub_info << "#{marc["502"]["b"]}, #{marc["502"]["c"]}, #{clean_end_punctuation(marc["502"]["d"])}"
