How to loop through an array and save data

Question

In my project, I have this following code

scenario = Scenario.new
scenarioTranslation = ScenarioTranslation.new

params[:title].each do | index |
      scenario.position = last_position + 1
      scenario.analysis_id = scenarioTranslation.scenario_id
      scenario.save
    end

Here the params[:title] is an array and I have to loop through number of array elements and save the scenario

Currently its saving only once. Can anyone tell me how to fix this error

Thanks

What exactly is it you want to do? Can you provide some context? Possibly it can be achieved in a better way. — Agis

Im a little bit confused about what your code should do but I think this is what you need:

params[:title].each_with_index do | title, index |
      scenario_translation = ScenarioTranslation.create
      scenario = Scenario.new(:position => (last_position + 1), :analysis_id => scenario_translation.id)
      scenario.save
end

Each iteration of the loop, create a scenarioTranslation object first, then a scenario object, set the array index as position of the scenario object, and save the scenario object.

params[:title].each_with_index do | title, index |
  scenarioTranslation = ScenarioTranslation.create

  scenario = Scenario.new
  scenario.position = index
  scenario.analysis_id = scenarioTranslation.scenario_id
  scenario.save
end
