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?

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?

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.

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?

Please cancel my question -further googling turned up the answer
For those who don''t know, you have to save the document so it is of a
certain kind first eg. rhtml then the lia snippet is activated by
simply typing lia and then hitting the tab key.

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

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

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

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

Hi:
I have lines in a table I wish to stripe BUT, every now and then

how to cancel/stop a script.aculo.us effect
I apologise for what is probably a totally noob question here, but I''m at a
loss after pouring over the docs and the source code for prototype and
scriptaculous...
After you''ve started an effect, how do you access it to cancel or change it?
I had assumed it was something like this:
myEffect = new Effect.Appear(element, {duration:1.5});
myEffect.cancel();
... but that

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

No comprendo - scaffold producing strange results
Hi:
I have a working invoicing application. All was well. Then I added
another table to the database. Following that I use script/generate
scaffold User
I was hoping that this would generated the usual stuff but just for
this model. It did. I can see all the views including _form, new,
list etc. However, athough I can access list as per normal, when I
try to create a new user it
