I''ve read a lot about the ORM magic of Active Record which allows you to address a foriegn key object directly... e.g. I have a books and people table where books has a column called person_id If I get myself a Book object called mybook I get to the person object associated with this book by saying book.person which is awesome and I love it. My question, how can I say "Go and...

Does anyone know if there is a package or other method of reading Genstat files directly into R. Genstat isn't listed in the foreign package. Many thanks, Graham [[alternative HTML version deleted]]

...state that, but i'm sure that the ensuing debate will clarify this. - aliasN is either a SID (e.g S-1-5-20-512, S-1-5-21-x-y-z-1029) or a SAM alias name (NOT a unix group name) note that: - when a user is added to a domain group, they can only be added to a domain group in the domain, NOT a foriegn domain (that is what aliases are for). - when a user is added to a local group (alias), the full SID must be specified. aliases can then have domain groups from foriegn domains added to them. in other words, administrators are advised to become familiar with NT account management _before_ attem...

...3. My actual database has a number of tables similar to Color, where all I really need to do is link a varchar field to the Products table. - Which solution would be more efficient? Using ID''s seems like too big a hit when viewing a product. - Can RoR support using a string/varchar as a foriegn key? Ie. Take out the Color ID and make the ColorName a Primary Key and link it to the Products table? Please help Jared Let''s say a table called Color has an int column ''ID'' and a varchar column ''ColorName'' and a table called Products lists Product...

Sorry for asking this but I am keen to get on and build an app based on RoR and have had a look around at FAQa and the like with no immediate sucess. What I am looking for is an explainantion of the rules/requirements for table/index/coulumn names with RoR. RoR appears to have a set of expected naming conventions which it would appear you can over ride but it would seems a hell of a lot

Hi all, quick question to all of you ruby on rails experts. I need to redirect the output of a url to an actual physical file. In other words, I need to have what I see in the web browser to intead be written into a file. Any ideas? Thank you. Darkwax -- Posted via http://www.ruby-forum.com/.

Given two models: User :name :email :address_id # foreign key Address :line_1 :line_2 :city etc. I want to have a form allowing a user to register, in which she''d enter an address as well, but how do I go about combining both objects into the one form? I''m new to this and following along with the Agile Rails book from the Pragmatic Programmers, but it

Please can someone put me out of my misery... I am missing the point here: I have a table of albums called: dealers I have a table of images: popp_images each dealer has 6 popp_images linked by foriegn key: albumid Each dealer can login using user_engine engine I restrict viewing for each dealer to their own images by assigning each dealer their own albumid. I list their images with: in my controller: def list @dealers = Dealer.find_all @dealer = current_user.albumid @popp_imag...

Dear all, I'm not sure whether this is a bug or not... But some help would be greatly appreciated. I have a dataframe, which I read in using read.xport (from the foriegn library) as the orginal data is in SAS format. 3 columns of this dataset are supposed to be dates, but read.xport doesn't recognise them as dates (all columns are read in as mode numeric). So I load up the date library and go ahead to convert the 3 columns into dates. So doing ... > library(...

Hi List, I have a client who has a TDM400P with 4 FXO. He has a problem them when some one calls, then hangs up it takes a good 10-15 seconds or more of the card to realize that the line was hung up on. The phones keep reigning After a bit it hangs up on the line. Also there has been some hanging. (After a user on the PBX side hangs up the card does not "release the line"). I am using

Hi All, Probably this has been asked numerous times, I apologize already! Can somebody point me to a good tutorial on how Rails works with relations? I know about database design and normalization, I also know about programming in general (and OOP for that matter). Only thing I can say is that I''m following the "Four days on Rails" tutorial by John McCreesh. He writes

For some reason using the 2.3.0 Version I can no longer stream Nullsoft Video. I have the correct tags in the config file but for some reason the server will not accept the connection from the encoder. I started up shoutcast DSP and it streams fine so I know it's not the encoder itself. Anyone else seeing this or can tell me how to fix it? -------------- next part -------------- An HTML

You should update the yes/no prompt to say that pasting the expected host key will result in appropriate testing, as well as providing some sort of error if the remote side *doesn't* match the key pasted in. I hadn't thought of cut

...d-dirty details. Small, easy-to-read quick-and dirty details. Along with this diversity, we have another complexity to add; the vorbis stream format is _NOT JUST FOR MUSIC FILES_ (am I wrong about that?) The metadata stream could easily contain close-captioning information (for the deaf, or for foriegn langauges). Certainly this is *not* the kind of information that would belong in the header details. That done, here's my what-I'd-like-to-see: I don't want an XML parser added to WinAmp. It just doesn't belong there. WinAmp should, however, be able to show me the title of the s...

I have not been able to get DB migrations to work at all in Rails 1.0 for me. On multiple platforms I continually get the same errors. It took me awhile to figure out some initial things, such as Migrations don''t seem to support Enum column types, and doesn''t really support Foreign key relationships (the constraints at least). After changing my DB schema to jive more with the
