Tricky model situatione
I have two models Club and users. users are regular authenticated
users and some of them might create a club. A club can also have
members (essentially users) and there are attributes and models that
apply to member but not to users.
Here is what I have right now.
Club => belongs_to :user
User => has_many clubs (since a user can host multiple clubs).
Now how do I fit this member model

http caching a dynamic page
Is it possible to take advantage of http caching/proxy caching with
dynamic pages? i.e. pages with section/part that can change over time
but certain part of the page remain the same. I would rather not keep
re-rendering the static part but insure the dynamic part are rendered
with fresh data.
I am using memcached mostly as an object store that I can minimize db
hits but I still am rendering a

max-age/header problems with nginx
0 down vote favorite
I notice that in my production enviornment (where I have memcached
implemented) in see a cache-control - max-age header in firebug,
anytime I am looking at an index page (posts for example).
Cache-Control max-age=315360000
In my dev environment that header looks like following.

Intended behaviour of "add user" and smbpasswd
Hi,
I'd like to upgrade my 2.2 samba to the latest 3.x stable, so I'm
experimenting with the new features of 3.x on a RHEL 3 clone. I've run
into some difficulty when using usrmgr.exe for administrating users.
I've filled out the 'add user script' define with:
add user script = /usr/sbin/useradd -g sambausers -c "Samba
User" -d /dev/null -s

Restart after crash
Hi,
Is it possible do have fsck to run automatically [without
operator intervention], if it was not a clean shutdown.
Right now, somebody has to bring a monitor & keyboard and say Y,
if not it will not run and verify the drive. This is for remote
headless servers.

Hosed by 4.2
Hi,
I have been using Centos since 3.0. I have been upgrading
regularly without any major problem.
4.1 to 4.2 has been a total disaster.
I ran yum update, it went through and a couple of hours later I
rebooted and X froze with the screen just being just fuzz
[regular rectangles, orange, green...] and the keyboard froze.
Could not do a alt-ctrl-backspace, nor a Alt-F1-6 nor Alt-Ctrl-Del.

counter_cache, has_many and belongs_to
I am a bit confused about counter_cache here. The API docs
http://api.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html
say that only the belongs_to association can take the :counter_cache
option. When I try to use it on a has_many I get an "unknown key(s):
counter_cache" error.
Why would this be the case? belongs_to means that this model has a
field with an id

counter_cache is not looking for children_count with acts_as_tree
Hi there, the acts_as_tree API says that I can set a counter cache and
that it will automatically increment the "children_count" column. I
did that but when I create a new page it asks for a "pages_count"
column instead.
Here is the relevant part of page.rb model:
class Page < ActiveRecord::Base

conditional updated_on update
Hi list,
I''ve got some counter_caches in a model. When these get incremented - say on
a page view - my updated_on column also gets updated. How can I
conditionally not update updated_on if just these counter_cache columns
change?
The problem with that is that I am using acts_as_versioned which clones the
record each time updated_on changes. I am successfully ignoring the
counter_cache

Ferret FileNotFound error after adding counter_cache to mode
I have a model that I''ve been indexing and searching with ferret with no
problems.
I just added a counter_cache for some voting functionality to the same
model and now when I perform the voting fxn on an object from that
model, I get the FileNotFound error as it looks for a file named
"_1c_1.del" ...which breaks my voting function.
I tried killing the server and my index

Pointer ownership with GECreateDevDesc/GEDestroyDevDesc
According to the "R Internals" document, for a custom device, I should
create a pDevDesc structure that gets passed to GECreateDevDesc.

Java Swing App
I'm rather new to Wine, and I'm trying to run a Java Swing application.
I'm having trouble with it. Has anyone else gotten Swing-based apps to
run?
I have a test case, basically a swing "hello world" app, and I haven't
been able to get it to work either. Here's what happens when I try to
compile it:

acts_as_tree counter_cache behavior is different than API docs
Before I file a ticket, I''ll query ya''ll about this:
The API docs for acts_as_tree''s counter_cache is to create a database column
called "children_count" to hold the counter_cache. I have enabled this
option in my model. While writing tests I wrote a test for creating children
from the a parent:
message = @forum_message["parent"].find

counter_cache is making a redundant SELECT before UPDATE
Hi,
I have the following code:
Message, belongs_to :topic, :counter_cache => true
topic = Topic.find_from_permalink(params[:id])
topic.messages.create(params[:message])
When the message gets created, then AR issues a supplemental SELECT to
retrieve the message''s topic and then updates its messages_count. Why is
that happening?

I''m trying to use counter_cache, but I''m not doing something right.
It is unreliable and I keep having to correct it manually. Is there a
good tutorial or reference on how to use it on-line? I have the AWDR
book, but I need something more complete.

Accessing overridden method

Should counter_cache fields be saved in the database?
As far as I can tell, the counter_cache option on a belongs_to model
doesn''t actually save anything in the database. For example, I have
the following models:
class Parent < ActiveRecord::Base
has_many :children,
:conditions => "deleted_at IS NULL"
end
class Child < ActiveRecord::Base
belongs_to :parent, :counter_cache => true

STI, HABTM & counter_cache

On each category record I''d like to maintain a product_count and deal_count
