questions about login_form_footer

[jf]

1. login_form_footer is described as an auth value method in login.rdoc, but when I try to call it with a single value (login_form_footer "hello"; or even login_form_footer("with_brackets")) it causes Roda to fail:

/Users/jf/roda/gems/gems/rodauth-2.34.0/lib/rodauth.rb:90:in `block in def_auth_private_method': wrong number of arguments (given 1, expected 0) (ArgumentError)

20:49:14 [rerun] Roda Launch Failed

I don't understand enough of the code now to be able to figure out why this is... I do know that in testing if I provide a block, I do not get the launch failure.

2. it would appear from testing that if I provide a value to login_form_footer that it will basically not display login_form_footer_links_heading and login_form_footer_links. Is this correct?

This is a bug in the documentation. It was originally an auth value method, and moved to an auth method when multi-phase login support was added. I'll update the documentation.

[jeremyevans]

As to your second question, if you use the login_form_footer method, and do not call super or call login_form_footer_links_heading and/or login_form_footer_links explicitly, then it will not display their contents.
