I am struggling to find the best way to set up relationships to achieve this so that it fits the rails idioms. I have a table of products and I want to be able to create a bill of materials for a product.. So a product can either be a single item, or a package consisting of several other products. I have created a table: ---- class BomItem < ActiveRecord::Base belongs_to :product

Hello all, I''m very new to Rails and I love it so far. However, there are some things that aren''t so clear to me. Let''s say a blog post can have many comments, and a comment can only belong to one post. A user can have many posts and many comments as well. (this part makes perfect sense): class Comment < ActiveRecord::Base belongs_to :posting belongs_to :user

Wayne, Hello, I saw a post of yours out on samba.org and was wondering if you might be able to shed a little light on a problem I'm having with rsync. My rsync source files are all off of nfs mounts and the destination directories are all nfs mounts. The owner and groups all end up as nobody/nobody on the destination, despite being all sorts of owners and groups on the source. Have you

Hi, I am trying to create a scatterplot, coding each point to one of 5 populations. I was successful when I did this for one set of data, yet when I try plotting other data a blank plot appears (although the axes are labelled and I can fit the regression lines from each population). I have tried a variety of things to fix this but nothing seems to work. I can plot the points if I do not

OK, here's a problem: I want to set the album replay gain in each track, but I'm using grip to rip and encode the tracks one by one. grip knows that all the tracks are on a single album, but FLAC sees them one at a time. I put the --replay-gain option on the FLAC command line, so it emits four comments into the vorbis commebnt block, e.g.: comment[9]:

I looked around on the web, but I found no guidance on this subject, so I'm guessing. Here is what I came up with. It appears to work on a limited sample of CDs. Can anyone comment on whether or not this is OK? My system is Mandrake 9.0. My Grip is 3.0.1 (as supplied with Mandrake 9.0) My flac is 1.1.0, built from the source tarball. Mandrake ships with 1.0.3, which does not appear to have

Hey. Last night I hacked grip so that it'd allow me to use vorbize and comments with grip. It's very ugly because grip'd need a bit of rearrangement in order to facilitate the way the vorbis comments work (that is, the comments are not added in after the encoded file has been written). Any one who wants to use it should patch grip-2.94 (http://www.nostatic.org/grip), and make sure you

I've seen a lot of people in many forums asking for vorbis frontends for Linux. A little bit ago, I switched my roomate over from encoding to mp3 to encoding to vorbis. To make the transition as painless as possible I wanted to let her continue using GRIP as her encoder frontend. To actually accomplish this project, I realized that if any real work was required on my part it would never be

All: I am using the standard voicemail in asterisk. Everything works well, except, if a users wants to record their own personal greeting, it doesn't playback. I can see the soundfile being created. I suspect it is a setting in the voicemail.conf, or an option I am over-looking on the grandstream, but if anyone can point me in the write direction, I would certainly appreciate the help.

I'm planning to deploy a personal dovecot IMAP server (i.e. I am the only user) in a FreeBSD jail. At present, I have IMAP deployed on the same host as one of my mail servers, which is running Postfix. I do like Postfix, but it seems to be a bit overkill for this particular situation. All my incoming MX are provided by Google. They handle the incoming mail and forward to my private MX,

Let's say I'd like to create a directory for urgent stuff I need to deal with. I'd put this line on ~/.config/user-dirs.dirs: XDGURGENTDIR=?\$HOME/Urgent? Right? But now, how do I assign a custom icon to it? I know I can just change the icon for any folder or file under properties, but that's not what I want! I'd like to do it "the right way". Using gnome, by

I have installed Personal Composer 2 in Wine 1.0.1 (Windows XP) under Ubuntu Linux 9.04. The Program seems to run OK, and I can enter notes into a musical sheet, but when I try to play the music there is no Sound! If I look in the Wine Audio Properties, the ALSA Driver is checked, and I have 'Wine midi driver' and 'Midi Through' under MIDI In/Out Devices; pressing the Test Sound

Hi guys, I'd like to know if there is a consensus about linking to personal websites on the personal wiki page every new user gets in the wiki. I maintain several games in the AppDB and created a wiki page recently describing some tricks for AppDB maintainers. I also created a personal wiki page, describing what I am doing on wine, what my email address is and where one can found my blog.

Good day all IS there a way to personalise the voicemail message when you leave a message? Thanks Altus

I want to have a "personal meetme conference", so when on a call I can transfer the other party to my personal conference with "#7". (I can then make other calls, and dump them into the conference using "#7" as well, then join myself by dialing "7"). Using: exten => 7,1,MeetMe(${CALLERIDNUM}|Mpd) this works as long as I originate the call. However,
