Page caching feeds and cache file extensions
I have a feeds controller which generates RSS and Atom pages. I put
''caches_page :show'' in it. The problem is that the pages are saved with
an html extension. As a result, browsers display the cached feeds as
HTML rather than XML, and feed validators complain.
There''s an option to set ''Base.page_cache_extension'' globally, but I
don''t want

has_many :through
Has anyone had much experience using the new has_many :though options

Are cache sweepers used?
After drawing many virtual blank stares in the IRC channel and finding
zero results on the wiki for ''sweeper'' I''m left to wonder whether
these are actually officially supported, or are on their way toward
being deprecated. Is there a better way of expiring caches on model
saves and deletions?
Sincerely,
Tom Lieber

What is .Instance?
With observers, you have to do (according to AWDWR):
ItemObserver.Instance
What is ''.Instance''? I''ve looked in both the Rails and Ruby docs and
don''t see any mention. I presume it''s like ''new''?
thanks

Trouble combining :has_many, :finder_sql and :conditions to create a sub-search
I''m sure there''s something right under my nose that I''m missing. I
have two tables with two parallel one-to-many relationships. I wish to
use the :finder_sql parameter to essentially ''or'' the two foreign
keys.
What isn''t working for me is performing a ''sub-search''.
Let''s say the tables are "stores" and

undefined method `include''
I''m getting this error in Rails:
undefined method `include'' for
#<MenusController:0x408efd1c>
The offending code is:
require "rexml/document"
include REXML
I see there may be a problem with GCC 4 on OSX, but
I''m using Redhat with GCC 3.2.

Has many through join table issues

following along at:

I have a directory of members, each member can belong to multiple
categories.

categories and admin/categories - different controllers and templates?
Is there some way to have these two sets of URLs use
totally different controllers and templates?
categories/list
categories/show/1
admin/categories/list
admin/categories/edit/1
admin/categories/destroy/1
admin/categories/update/1
Besides, of course, using different controller names
;). The first URL is publicly accessible, while the
second contains admin functions. Also, with the

select options for HABTM?
I''ve looked through the docs and the wiki and can''t

Override has_many :order at run-time?
Is it possible to override has_many''s :order attribute at run-time? e.g.
something like:

...
<% for category in @site.categories(:order=>''rank'') %>

Redirecting in a view?
Is there a way to do this in a view?
<% redirect_to ''http://url.com'' %>
All I can think of is outputting a link and using
Javascript to click it, or probably do something like
''doc.location(url)''.

Easy way of dealing with nil properties in templates?
Is there an easy way to deal with nil properties in
templates? All I''m aware of are these methods, and
it''s quite tedious and surely violates DRY.
<%= @member.name unless @member.name.nil? %>
<%= @member.name.to_is %>
<%= "#{@member.name}" %>

Why you MUST use SCGI for Rails development
Hello happy Railers,
I used to develop with a local out-of-the-box Apache and load times were
pretty slow (like a few seconds each page). "Well, it''s the price to
pay for no compile / cache / etc..." I thought. Nonsense. Yesterday I
installed SCGI, and now I''ve got the best of both worlds: rails
development env uses my very latest modifications, while SCGI ensures I

Dedicated Host Recommendations?
I currently have a dedicated server at ev1servers, but
it''s getting rather antiquated (Redhat 9) and am
looking to upgrade. I''m thinking about serverbeach.com
- one of their CentOS servers. Anybody have any
recommendations for dedicated servers on which to run
Rails? Hopefully less than $200/month.
Thanks!

Difficult process of restarting SCGI, Lighttpd, Apache, sessions
I''ve managed to get Rails working using Apache->Lighttpd->SCGI. Restarting everything is really
difficult. This appears to be the process:
- stop apache
- stop lighttpd
- stop scgi
- make sure scgi still isn''t running (it sometimes does) - if it is, kill it
- delete all session files (they often cause permission errors)
- start scgi
- start apache
- start lighttpd

Building a conditions clause (for find) of multiple optional params?
I want to be able to find items according to various params - category_id, member_id, type_id,
rating, etc. What I have now is something like:

@items=Item.find(:all, :conditions=>["category_id=?", @params[''category_id''])

I think options_for_select is backwards
With a hash such as:
stuff = {''1''=>''desc 1'', ''2''=>''desc 2'', ''3''=>''desc 3''}
options_for_select(stuff) will output:
<option id="desc 1">1</option>
<option id="desc 2">2</option>
<option id="desc 3">3</option>
