Bug in Rails 1.1 implementation of before_filters
I just spent a few hours tracking down a bug in Rails 1.1, so I thought
I''d post the issue and a workaround just in case anyone else hits it.
I designed a security enhancement so that controller methods can be
protected by preceding them with a role. The standard Ruby
method_added() callback is used to detect when controller methods are
added, and then I manipulate the

Serialized object behaves weird
Hi!
I got a class named EinsatzFilter which I serialized to session. Before
saving to session it works afterwards I keep getting the message:
"undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from
ActiveRecord::Base inherited class.
Code:
class EinsatzFilter

Rewriting with an after_filter
All -
I''m completely new to RoR and also new to programming in an MVC
structure...
The Pragmatic Programmers guide to Rails says, temptingly:
"After filters can be used to modify the outbound response, changing the
headers and content if required. Some applications use this technique to
perform global replacements in the content generated by the controller?s

Misc notes concerning view_paths
Hi all,
I''ve been playing in the trunk with putting stuff in different dirs
to keep files from a reusable framework separate from the app files.
Here are a few considerations regarding the view_paths setting:
config.view_path is used to set both action_controller.view_paths and
action_mailer.template_root. We get some buggy/unexpected behavior

rendering in after_filter
Hi!
Is it possible to render the action within the after_filter method, or
is the rendering performed before?
I have something like this:
class FooController
after_filter :send
def a
@content=...
end
def b
@content=..
end
protected
def send
send_data(@content,...)
end
end
However, when calling the action a or b, the @content doesn''t get sent,
but instead

Do you know of any way for me to stick a meta tag in using a

Is there a way to abstract the updating of other parts of the page after an Ajax request without putting using the standard view file?
Hey all,
I''d like to abstract the process of updating different portions of the
page after an Ajax request has taken place. Rather than simply putting
the extra view logic in the standard rjs template, it seems to give
better separation if there is a split between the core view logic (ie,
inserting a row in a table), and updating any associated portions of
the page.
Is this possible? I

Mongrel caching
I am using mongrel to serve static as well as dynamic pages.
The static page''s controller contains the following line of code:
after_filter {|c| c.cache_page}
This code caches that page as a static html page that does not have to be
rendered form multiple files (the view and layout). I got the idea to do
this form the rails recipes book. It definitely cached the pages. Wen I

[Idea] session-wide persistent variables
I was thinking about having instance variable stored and fetched from
session container automatically before calling an action and after the

def alfa
person = ''John Smith''

Using ActiveRecord outside of Rails error
Hi,
I have a script which is using ActiveRecord for database queries outside
of a rails app. It seems to work fine for doing finds on models, but
everytime I try to create a new model object and then save it, I always
get the error:
MyModel.new({:name=>''foo''}).save gives
NoMethodError: undefined method `read_inheritable_attribute'' for
