Question

How do I split this array and store into the database?

I have three fields in my model called Question_id, Answer_id and Phase_id.

I have a result like:

question_hash_string = "{\"5\":[\"5\",\"0\",\"\"],\"25\":[\"25\",\"1\",\"3\"]}"}

Which looks like {5:[5,0,1], 25:[25,1,3] ... }.

I want to split the array and store the results into the three fields in order Question, Answer and Phase of each set.

In my Batch table, I have three columns: question_id, answer_id and phase_id.

The first value of array[5,0,1], 5 goes to question_id, 0 to answer_id and 1 to phase_id. In the second row 25 to question_id, 1 to answer_id and 3 to phase_id.

Answer 1

You can do this:

hash_values = JSON.parse(question_hash_string)
hash_values.each do |k,v|
  b = Batch.new
  b.question_id, b.answer_id, b.phase_id = v.collect(&:to_i)
  b.save!
end
