Can't handle <% if logged_in? %> when running for the first time

Mister_Blood_R · April 17, 2008, 9:51pm

My app can’t handle <% if logged_in? %> when running for the first
time. It has no registered users, but why does it have to complain? It
handles everything just fine after I register the first user manually
through www.mysite.com/users/new.

I’m looking at the above code and what I see if an internal server error
and the beginnings of an <% if . . .%> and then an <% end %> but then
after that I see and <% else %> that is not matched to any <% if. . .%>.
My guess is that you don’t want that <% end %> in there.

What about the <% if admin? %> ?

@Rails:

Have you patched authenticated_system at all? My guess would be that
either:

You patched authenticated_system to refer to Site
Your current_user refers to Site (or, if you’re added a NullUser
form when there is no one matching authentication then it does).

A require in authenticated_system or (null_)user should do the trick.

Also, if this is truly a once-in-an-installation problem, then why not
consider having your create_user_table migration create an admin/
superadmin user with a default password?

Your right I didn’t see that. I might have miss led you. Just out of
curiosity what does that logged_in? method do? Is that a method you
wrote? From that error that looks like where you problem is originating
from.
