The error in the screenshot is not to do with the devise helper current_user. It is in regard to the user_avatar helper.

In your view, you are calling the method with 0 arguments:

<%= image_tag(user_avatar) %>

But the method is defined with 1 parameter:

  def user_avatar(user)

Hence the wrong number of arguments error in the screenshot.
