  # We are going to assign the attributes only to handle the validation of the avatar before accessing
  # `create_conference_speaker!` which uses `create!`, and this will render an ActiveRecord::RecordInvalid error
  # After we assign and check if the object is valid, we will not save the model to let it be handled the old way
  # If there is an error we add the error to the form
  # We are using this method to assign the conference because if we are trying to assign all at once, there will be thrown a
  # Delegation error
