Ruby on Rails: Access values from form in controller

Question

How would I get all the values in the form input fields below by iterating through ans[n] where n = 1...3 in a controller?

<input type="text" name="ans[1]" value="Test 1">
<input type="text" name="ans[2]" value="Test 2">
<input type="text" name="ans[3]" value="Test 3">

You can loop on this params by doing this in your controller:

#controller
params[:ans].each do |value|
  puts value # should print the values for each input
end

If the params[:ans] is an array of hashes, you can access to its attributes like this:

params[:ans].each do |answer_attributes|
  puts answer_attributes['1']
end

If params[:ans] is this array: { '1' => 'Test } , how do I access 'Test' ?

You can loop through the values of the param hash.

params[:ans].values.each do |value|
  puts value
end
