Hiding organs from index list with attribute switch

This code should be run in console:

Organ.update_all(status: :visible)
helsinki_uni = Organization.where(key: "helsinki").first
Organ.by_university(helsinki_uni).each{|organ|organ.update_attributes!(status: :hidden)}
Organ.where(term_end: Date.parse('31-12-2015')).by_university(helsinki_uni).each{|organ|organ.update_attributes!(status: :visible)}

Aims to make these calls visible:
-calls from other universities' that Helsingin yliopisto
-calls for the current election in Helsingin yliopisto
