Issue looping

qn_array.each do |i|
  #building 3 questions, you can build any number you want
    3.times {self.questions.build(:question_no=>i,:answer=>"",:score=>0) }    
    self.save
end

The array is contains the id of the list of generated questions.
The issue with the code is that when I view the database only 1 entry is generated.
The array definitely contains more than 1 elements
Even if I feed the method (using rails console)
@s.gen_questions([1,2,3,4,5,6,7,8,9])
@s.save
It still generates 1 question only.
Update: Using Javix code creates the number of entries correctly but the question number is not the value of each element in the array, but I need the number of entries created to be dynamically determined by the number of elements in the array.
eg @array contains [123,456,446,8,2,6,7,32]
So the number of entries to be created is 8 and each time question number is 123 for the first entry, 456 for the second entry and so on.

Have you tried adding a puts to verify that the for-each loop is behaving the way you think it should?

 def gen_questions(*qn_array)
    if !questions.nil?
      qn_array.each do |i|
      self.questions.build(:question_no=>i,:answer=>"",:score=>0)
      puts “:question_no => #{i}, :answer => \”\”, :score => 0”
      self.save
      end        
    end  
  end

It might have something to do with how your Model is setup. (ie. validates_uniqueness_of)

I don't know then.  Sorry.
