This is likely a painfully newbie-ish question, so please bare with me :)
I'm muddling through my first rails application, and decided to use the
Login Engine to handle user authentication. Now, according to the
README, I should be able to "use current_user method provided by
UserHelper", like so:
Welcome <%= current_user.name %>
I've put that line in my application.rhtml, and return the following error:
undefined local variable or method `current_user' for
#<#<Class:0xb7875280>:0xb7875258>
which seems to suggest I haven't done something correctly.
Now, I can find where current_user is set in
vendor/plugins/login_engine/lib/login_engine/authenticated_system.rb
I'm still trying to work out what goes where in rails, but I figured in
order for the method to be available globally, I needed to move that
definition into app/controllers/application.rb. Still received the same
error, however.
I then tried adding the definition for current_user to
app/helpers/application_helper.rb, and that sort of did the trick.
"Welcome <%= current_user.name %>" now translates properly in my layout.
My real goal, however, is to get usermonitor to work
(http://wiki.rubyonrails.org/rails/pages/Howto+Add+created_by+and+updated_by/versions/7),
and current_user still does not appear to be accessible by this module.
When I attempt to edit an object in one of my models, I get the error:
undefined method `current_user' for User:Class
So I gather app/helpers/application_helper.rb is likewise not the
correct place for this.
I then try putting it in config/environment.rb (which seems even less
likely, though at this point I do have to concede 'what do I know?'),
which also appears to work as far as my application.rhtml is concerned.
But when I try to edit an object, I now get:
private method `current_user' called for User:Class
This feels a bit like progress, but I'm stumped regarding how to make
this method public (and whether or not that's really what I want to do).
If I understand things correctly, methods *are* public by default, and
only become private when "private" is placed before their definition?
Which is fine, except that there is no instance of "private" in my
config/environment.rb
At this point, I'm stumbling blind, and don't know if I'm even remotely
headed in the right direction. If somebody could give me a nudge in that
right direction, I would be so very grateful!
Thanks in advance,
Gwen
