I'm trying to use LoginManager and am running into a little problem, which
I'm sure is based in a not-deep-enough understanding of acquisition issues.
Bloop
---acl_users
------Z MySQL DA
------SQL_get_password [SQL Method, taking username & password parameters,
tested & works]
------xuserAuthenticate [DTML Method: contains the line <dtml-in
"SQL_get_password(username='foo',password='bar')">]
------Test [DTML Method: contains the line <dtml-let
ret="xuserAuthenticate(username='foo',password='bar')">
If I try to "view" Test, then I get the nasty traceback below. If I view
xuserAuthenticate, no such error is reported. I suppose this is because
dtml-let puts a "strange" acquisition context in place during the execution
of xuserAuthenticate...an execution context that does not include the
containing folder of Test (namely acl_users). Or is this due to some
strange properties that I am not yet familiar with of acl_user folders?
