i am trying to create a system so that different users have different
priviliges on my application. i was going to modify my authorize
function so that i could pass the required role to it and have it check
the current user for that role.
i am using before_filter and would like to have just one function
instead of writing one for each role like so:
authorize(role)

CAS Authentication filter.
Hi
CAS is a centralized authentication service, and the cas_auth filter can
be installed to automatically make your web application authenticate
against a CAS server. The SVN path to the plugin is
http://svn.ki.se/rails/plugins/cas_auth
and a homepage with some information can be found at
http://opensource.ki.se/casauth.html
For use, just install the plugin in your application and set

Autocompleting InPlaceEditor
Hi,
I''ve created some extensions to script.aculo.us InPlaceEditor, allowing
the use of either server-driven, or local autocompletion. I''ve also
created new helper methods in Rails for this functionality.
My question is, is there any interest that I package this and make it
available as a plugin, or something like that?
Regards

Configuration search order
Hi
I''m in the process of deciding how a plugin should be designed to make
configuration as easy as possible. Right now I require the plugin from
init.rb, and set some configuration options (as class attribute
accessors) from environment.rb. Then I tried setting these from
environments/development.rb instead, and to my surprise this didn''t
work. It said the class in question

Plugins and svn
Hi railers,
What do you do when you must use a plugin in a rails app that is under
subversion?
I think that an approach is simply install a version of the plugin, and once
all the test pass, commit the plugin itself to the repository, inside the
/vendor/ of the app. If a new version of the plugin is released, your app is
still using the working one (although the new version could work too).

InPlaceEditor with Autocompletion
Hi
Rails AJAX controls are very handy, and the InPlaceEditor is probably
one of the easiest and most neat of them all. But, it doesn''t do
autocompletion. I''ve rectified that situation. The plugin provides a few
new helpers and a new JavaScript-file that extends the
Ajax.InPlaceEditor with local and remote Autocompletion features. So,
just install the plugin, include the

Swedish Rails
I would like to announce my plugin Swedish Rails.
Rails provide many goodies and helpers for you, but some of these are
dependant on your user interface being in english. Date controls, for
example. Pluralization is another. And have you ever tried to capitalize
a string with Swedish letters in them? Then you know it doesn''t work
that well. Until now, that is. You install this

Passing Ajax.InPlaceEditor options
I''ve followed the instructions in the Rails Recipe #1 and have the
in_place_editor_field working but now I want to tweak how it looks and
behaves. I''d like to be able to override the default yellow highlight color,
which is done using the highlightcolor param according to the scriptaculous
documentation (unless I''m missing something).

Database configuration across developers!
Hi,
I have what might be a silly question but is there any way to put some
of the database configuration information into a separate file? For
instance, in config/database.yml I have:
developer_database: &developer_database
adapter: mysql
username: me
password: something
host: 127.0.0.1
development:
<<: *developer_database
database: foobar_development

Array#chunk method, maybe someone will find this useful
class Array

Don''t understand :: in ActionController::Base
Maybe this should apply to Ruby forums directly, but I''ll try here.
I understand the concept of classes and subclasses thanks to the
excellent "Programming Ruby - The Pragmatic Programmer''s Guide".
However, I don''t understand what :: signify in terms of inheritance,
parent and child in e.g.

ActiveRecord-JDBC is coming along
The ActiveRecord-JDBC adapter is rapidly maturing these days. I got the full
set of AWDwR2 migrations to run with it against MySQL last night, and Ola
Bini has gotten migrations working well against Oracle and Firebird. We also
have SQL Server support running most of our test cases (under non-Windows
environments too!) and have started adding support for Derby and HSQLDB

cannot get past "Booting WEBrick"
Hi Everyone,
I am following the ''Agile Web Dev. with Rails'' book, and I used instant
rails to do the install on a Windows machine. Everything seemed to work
fine until I got to:
Booting WEBrick...
After that, nothing happens. I tried creating a new rails application, but
I get the same
problem. I also tried reinstalling to no avail.
Any ideas?
Thanks for the help.
