Fun with Find Conditions
You can pass more than simple strings to find conditions. Arrays, ranges, and nil values can be passed as well. In this episode you will see the tricks involved with passing these odd objects to find conditions. (Update: audio fixed).
Task.find(:all, :conditions => ["complete=? and priority=?", false, 3]) Task.find(:all, :conditions => ["complete=? and priority IS ?", false, nil]) Task.find(:all, :conditions => ["complete=? and priority IN (?)", false, [1,3]]) Task.find(:all, :conditions => ["complete=? and priority IN (?)", false, 1..3]) Task.find(:all, :conditions => { :complete => false, :priority => 1 }) Task.find(:all, :conditions => { :complete => false, :priority => nil }) Task.find(:all, :conditions => { :complete => false, :priority => [1,3] }) Task.find(:all, :conditions => { :complete => false, :priority => 1..3 }) Task.find_all_by_priority(1..3)
