repost - Can one edit the file that generates the scaffolding.css?
I am reposting this because not only am I VERY interested in the
answer but because I think it would also be useful to many, many people.
We kind of have a house-style here, so it would be nice if the
generated scaffold.css would accommodate that. My questions are?
Is it possible?
Is it safe?
How?

counting rows via associations
Hi:
I have a table called clients and each client has many lists (a
has_many and belongs_to has been created in the class.
What I need to do is get a count of the rows in each list for each
client. I was hoping I could do something like
client.lists.count but it does not seem to work. Any suggestions?

Is Webrick good enough?
Hi all,
On the rails list I''ve seen that it''s hard to integrate Rails with Apache
(especially apache2), that it''s hard to change the default port (3000), and
that Apache runs Rails stuff slowly.
Is it reasonable to run Rails stuff on Webrick while simultaneously running
other stuff on Apache? How does one simultaneously run two rails applications
on Webrick, when

How do I write a generator?
I''d like to take some advice and write a generator to change the
scaffold.css. How do I do that? I looked on the wiki and googled it

Any help would be much appreciated.

Would someone like to tell me why this code will not solve my problem? (it''s short)
I am building an invoicing system but cannot use the auto_increment
field to determine the invoice number (because they are running 3
different companies off the one system. I need to find the last
invoice number from any given company and then add 1 to it to get the
next invoice number. BUT, there is a unique case on the very first
invoice produced because there is no earlier invoice

I''d like to edit the scaffolding file - is it possible?
I notice that I begin each project with a standard css file which is
the one produced by scaffolding PLUS some other stuff. I could cut
and paste a copy from an old project but I thought it would be
"cooler" amongst other things (like more efficient) to just have the
scaffold.css file be created for me.
Is it possible? Is it safe(ish), What would I have to do?
Thanks in

I don''t even know how to ask the question (4 lines of code)
I create a hash using this line of code @x = Account.find(:all)
I then want to go through each element in turn and add a key value
pair to the end of it. I thought this would work, but it does not.
@x.each do |a|
a.merge({"balance"=>50}
I used merge because I thought ''a'' would be a hash (how do you find
out the type of an object?)
I then guess it was

A book we may wish to buy
Hi:
Some French fellow posted a notice yesterday about a book that had
come out. It''s called "Ruby on Rails" and is apparently by DHH &
David Thomas. Is this a scam? If not, does anyone know where I can
buy this book in English? I''ve searched the usual places but can''t
turn anything up.

dumping out mysql data only (no structure)
Is it possible? It is mentioned in AWDWR but I cannot find that
option in the MySQL documentation. I can dump the whole db or just
the structure, but I''d like to be able to dump just the contents.

Trying to grasp the difference between local variables and instance variables/
Hi:
Would it be fair to say (or completely out to lunch) that a local
variable is local to a method and an instance variable is local to an
object. Thus an instance variable is a sort of limited global
variable or super-powered local variable. Its scope is larger than a
local but smaller than a global. Or that it is a global within a
limited domain (the object).
or is it a whole lot

How can one use GRUFF with locomotive ( I guess there is a wider question here, also)
Hi:
I love Locomotive and use it exclusively for my rails projects. I''d
like to install GRUFF and give it a try (a graph image creation
package). I know I can do sudo gem install gruff from the command
line for normal ruby and rails. How do I make gems available to
Locomotive?

Pfr tmp files, FreeBSD and Linux
I currently have 2 samba servers (3.0.25a) one running FreeBSD 6.2 and the
other running CentOS 5. Both are setup the same and using the same smb.conf.
The FreeBSD server works great, no problems. The linux server works great
too except on logout. When a user goes to logout, windows errors with

Looking for a textbook that is more concise than Applied Linear Statistical Models (2004 version)
Hi,
I know this is a little bit offtopic on this list. But I can't find a
more appropriate forum that I can ask. If there is a high quality
forum on statistics textbook discussion, please let me know.
I am reading Applied Linear Statistical Models. One drawback that I
feel about this book is that it discuss many examples, which is to
distracting. Numbers are give in those examples. Comments

Xen on Centos 5.5 vs 5.3 and stability issues
I've recently upgraded a Centos 5.3 machine to Centos 5.5. The
hardware isn't HVM capabile so I'm only running para-virt guests.
Using a vanilla i386 kernel boots without, but the newer kernel-xen
locks up the Dom0 after a couple of minute. I'm only booting into
single user mode for these tests so no VMs are active.
*kernel-xen-2.6.18-128.1.10.el5 - no issues

What am I doing wrong!!!
Hi:
@x = Invoice.find(:first)
if @x
do one thing
else
do another
end
This ought to work but does not. I think that @x is nil but if I
test for existance or @x != nil or @x.attribute != nil - my code does
not respond correctly. What is the value of @x if there are no
records yet in the invoices table?
Thanks in advance.

I am starting a project in rails and I wish to change scaffolding.
I''ve already done some changes like prepare all texts for locale. Now
I am wishing to change the way it generates the _form partial. Could
someone give some guideline so I can study such thing?

generate scaffold ignores controller parameter

Can I reset the cycle helper?
Hi:
I have lines in a table I wish to stripe BUT, every now and then
there is another type of line, a section header line. I''d like to be

two classes the cycle helper is cycling between. Is it possible? If
so, how?
