DRY methodology
because I am a grasshopper...
Now that I can sort my ''list''...is there a logical way of not repeating
myself to having essentially the same list view with multiple sorts?
i.e.
def list_cl
# ordered by clients last name
@placement_pages, @placements = paginate(
:placements,
:include => [:client],
:order_by =>

Clearing browser history?
Hello everyone,
I''ve got an app where, when a user logs out, I want the browser
history to be cleared so no-one can go back and see what the user was
doing.
I remember seeing info on how to do this before - can''t find it in
Google (the search terms "clear", "browser" and "history" aren''t that
great!), which means I can''t remember

Plugins? Components?
Hi,
Newbie here :)
Can someone help explain the difference between "plugins" (put in the
/vendor/plugins directory) and "components" (put into the /components
directory)?
Is it just that "plugins" have an init.rb file that is automatically loaded?
Also, how can I dynamically find out which files/controllers are
available in the /components directory?
Thanks,

linked table confusion
placement.rb
has_one :client
has_one :case_manager
client.rb
belongs_to :case_manager
has_many :placements
case_manager.rb
has_many :clients
has_many :placements
I am trying to create a view file for placements.
I can pull columns from clients table in this view by using...
<%= @placement.client.wholename %>
but if I use
<% @placement.case_manager.wholename %>

Please e-mail (not only post) the Forum Instructions URL
Am I just blind, or are there no links to the instructions, e.g. the
Search syntax or how to get back to a thread I started on RoR?
Or do those links, buttons, whatever only show / work in IE?
Thanks for any help; sorry if I can''t figure out something I should be
able to.

Possible Rails Security Issue?
I have an e-commerce site and users check out with a form. The
results of that form are sent to a "confirm your order" page via
POST. I take great pains to NEVER store the full credit card number
on my server--just the last 4 digits. I was very surprised to find
that by default Rails will record POST requests with parameters in
the production.log. And those parameters

PNG and Alpha-Transparency
Is there a prototype / extension which will assist in cross-browser support
of PNG images?
http://www.alistapart.com/articles/pngopacity/
It seems to me that a class could be developed which would zip through the
DOM and make changes where needed for IE 5.5 / IE 6.0 to handle PNG images.
I don''t want to write one if it''s been done before.

pagination_links help
I want append custom query parameters to my pagination links, like
?page=1&foo=bar. I can''t quite figure out how to do this with the
pagination_links helper, although I believe the API says you should be
able to:
pagination_links(paginator, options={}, html_options={})
options are:
:params: any additional routing parameters for page URLs
Has anyone tried this?
thanks,

Globalize plugin, now I have two classes with the same name
Hi, newbie here.
I''m using the Globalize plugin, which defines a model with the same
name as one of my existing models. We both use a model called
Country. The Globalize Country model (within vendors/...) is wrapped
in module like this...
module Globalize
class Country < ActiveRecord::Base
...
end
end
And this is my Country model (within app/models)...

I'm trying to boot a dos floppy stored on a disk image which is initially

minimizing device-dependent code in graphics scripts
Here is a common scenario that I and probably others often face:
- I write a script, test.R, to produce some graphs, viewing them
on-screen and tinkering until they look right
- I want to save image files (e.g., .png), so I wrap each plot in device
driver calls, e.g.,
png(file='test01.png', width=600, height=600);
plot(1:10)
dev.off()
png(file='test02.png', width=600,

Liquid - form helpers? multiple liquid templates?
Hi,
Its taking me a long time to get my head around the Liquid plugin. I

- How difficult would it be to add some kind of Filter or Tag which
would allow other Liquid templates to be included into the current
Liquid template (eg. similar to render(:file => "filename")
