So I have: Order - has many LineItems LineItem - belongs to an Order

Hi, 1) I have noticed that when I use the aggregate function it outputs numbers in the results. for example: aggregate by product group.1 Aggregate 1 ProductA 1000400.00 2 ProductB 23232323.00 3 Missing 232323.00 is there a way to suppress the numbers infront of aggregate outputs.

I have an application I''m working on which allows me to upload files. The files are stored somewhere in the public directory so that they can be accessed directly.

Before I start working on a solution, has anyone else already solved this

I submitted this earlier, but the web forums went down and I''ve screwed up the thread, so I''m starting over. I''m trying to built a document upload system. The system has a main Document model with different subclasses for different types of documents.

Hello, I want to install a bunch mongrel servers with an apache in fronthead, all that on OpenBSD. But OpenBSD is released with a homemade Apache 1.3.29 patched by the OpenBSD team. I really want to keep this version of apache and I don''t want to change it to Apache 2.x (because of the security and the license but it''s not the point here). But for having mongrel, it has to be

I haven't quite figured out how I can change the environment of a function. I have a main function and want to use different auxillary functions, which I supply as parameter (or names). What I want to do is something like this: main.fun=function(aux.fun,dat){ x <- 1 fun.dat() } aux.fun.one=function(){ mean(dat)+x } aux.fun.one=function(){ median(dat)-x } I don't want to

I have a model like so class Product < ActiveRecord::Base has_many :image_links, :order => :position has_many :product_images, :order => ''image_links.position'', :through => :image_links end The problem is that :order clause just gets ignored. How do you server records in a specific order when the order column is on the join model?

Hello, I am having some trouble with NMB. My linux box doesn't appear in the network neighbourhood (win 98). In spite of this, I can still access the linux shared directory.

I have an existing openldap schema which is handling mail, web and ftp services right now. I am trying to get a windows machine talking to the same filesystem as apache on linux via samba and read/write using the correct uid/gid.
