How to store the contents of a field in Ruby?

I need to extract the text that was generated from faker gem and use this value to pass it as a parameter to another field.

However the solution I found is returning me blank

[![screen_cadastro.input_first_name.send_keys(Faker::Name.first_name)
  @take_name = screen_cadastro.input_first_name.text

pp @take_name    #return blank][1]][1]
