Functional tests and protected actions
Hello!
I have certain methods in my Application Controller, that I need to access.
Namely ApplicationController#logged_in_user
The problem is, that when I try to access it, I get:
NoMethodError: protected method `logged_in_user'' called for
#<AdminController>
Any ideas how I can circumvent that?
Or are functional tests really not suited for any kind of logins and session
work?

User Authentication
I''m trying to create a simple authentication system but am failing
miserably. I''m (sort of) following the "Logging In" chapter of the Agile
book. Ideally, any access to http://example.com/publish (and any of its
subdirectories) should redirect to http:/example.com/publish/login when
there is no valid session user_id.
Code so far:

Secure but elegant destruction method
Hi,-
I am looking for a clean and secure way for an ActiveRecord instance to
delete itself. Say I have a User model in my app. Then the destructive
action would be /users/user_id/destroy. If this action is not secured by
a filter like:
(*) before_filter :check_administrator_role, :only => :destroy
then any user could potentially log in and start issuing:
/users/1/destroy
/users/2/destroy
.

How can I fix this problem? I remember that I saw in

Handling/Catching Exceptions
Hello!
I was wondering, sometimes I raise an exception in my Rails apps, e.g.:
raise SecurityError unless @post.user == logged_in_user
Now: is there any way to catch that SecurityError exception somewhere
and render a custom template? E.g., I want to render
''app/views/content/security_error.rhtml''
Does anyone know how to do this?
Thanks a bunch,

Accessing datetime elements from hash passed to method
I''m passing hash (called ''params'') to a method. Some keys (one of them
is called ''starts_at'') in that hash have date as a value (taken from
datetime_select helper). I want to access the date elements like date
only or time only but I''m just out of ideas.
def self.new_meeting(params)
str = params[''starts_at(1i)'']

Sessions in Layered Dispatching
Can you use sessions in layered dispatching? I used them in direct
dispatching without any problems, but switching to layered throws an
error (saying session doesn''t exist).
Sorry if this is a double post, Google Groups isn''t posting my message
for some reason.

ffmpeg + mp3 convert
Hi all,
I am using paperclip plugin to upload mp3''s. Before I save the mp3 I
would like to convert it to a smaller size.
I am using ffmpeg library and in my Track model I am calling:
before_save :convert_mp3
def convert_mp3
system("ffmpeg -i #{mp3.to_file.path} -vn -ar 44100 -ac 2 -ab 64 -f
mp3 #{mp3.to_file.path}")
end
But this fails. Am I missing something?

Layout not rendered when render_component used
Hi
I''ve got a login action that handles authenticating users, setting
cookies and, via its view, displaying an HTML snippet containing a form
with username and password fields. It''s called from the main
application.rhtml layout so I don''t need to have a seperate page (away
from the main site) with a login form.
My user model is more-or-less the same as in the Agile RoR

Should controllers be "smart"?
I''m working on a small project with a friend, and one of the things we
needed to do was send off an email whenever someone signs up an
account. His implementation was pretty simple - throw a
deliver_welcome call inside the controller after the signup. I''m sure
that this is a pretty common thing to do.
The problem, in my mind, was that the app now became tied to two
places -
