Paul - Just an update. Although changing the partial as you suggested
allowed the "home" page to render properly, I think it also kept
Authlogic from working properly.
When the partial contains this:
<% form_for UserSession.new :url => user_session_path do |f| %>
I get nothing from Authlogic when I hit the Login button with no
credentials entered.
But when I revert to its original form:
<% form_for @user_session, :url => user_session_path do |f| %>
Authlogic gives me the following response:
****************************
1 error prohibited this user session from being saved
There were problems with the following fields:
* You did not provide any details for authentication.
****************************
So here is how I was able to get it working:
- Changed "home" controller as follows:
def index
@user_session = UserSession.new
end
- Changed view for "home" controller (i.e. - index.html.erb) as
follows:
<%= render :partial => "user_sessions/user_session", :locals =>
{ :user_session => @user_session } %>
This seems to work.
Thanks for pointing me in the right direction.
