I come from a db world.
Can someone interpret this please, "self.questions.reject{|q|
q.nil?}.all"
I'm overwhelmed by the syntax in the second line,
"self.questions.reject{|q| q.nil?}.all"
>> def needed_questions
>> self.questions.reject{|q| q.nil?}.all
>> end
>> something like that.
i can somewhat understand self.questions.... but after that it is way
over my head.
I just completed reading "Simply Rails2" book and thought i could
understand.. but this line is "self.questions.reject{|q| q.nil?}.all" is
complicated.
Please help.
thanks,
radha
