probablly a newbie question: Rails does not support a table with multiple keys ??? it seems that the ActiveRecord set_primary_key method can only set the column name... (hope i''m wrong there) example: table A - P.K id, string name table B - P.K id, string name table C - P.K a_id and b_id, both are also foreign keys. Thanks, Amir. -- Posted via http://www.ruby-forum.com/.

How many people out there are doing Rails development on a Mac Mini? I''ve been eyeing up the MacBook as well as the new MacMini trying to decide if I want to splurge. I''ve been doing very little Rails development thus far which makes the investment a little hard to justify. The Free Mini Mac ( http://minimacs.freepay.com/?r=16778073) offer seems like the best route but

I did some searches in the mailing list and on the web but I can''t seem to find the answer to this, but it''s pretty much a noob question.

I am creating an app that will out grow an int(10) unsigned for the id field, ie. 4,294,967,295 records. What are my options, I have looked at the GUID plugin that lets you use a 32 char GUID, but I still want the id''s to be sequential, and (I think) that the overhead of searching a varchar field will be too big for such a large number of records. It does not appear you can use a

I could use some direction. I need a form to collect information on a user''s allergies. I want to present them with a form much like the one we fill out when we see a new doc where you just check-off the things you''re allergic to. When the form comes back to the controller I want to add a record to a table for each allergy they''ve checked. I was thinking I should

I''m a complete newbie when it comes to Ruby on Rails. I have lots of experience in PHP, but yesterday was the first time I sat down and began developing using Ruby on Rails (I''m impressed!). Anyway, I''m having a problem with edit/update of records when using form validation. Here are my files for reference. ticket.rb ============ class Ticket <

Hi all, I have several models which all have an email field. This email address should of course be validated and for that I have this nice regex. But now I have the email validation method copied throughout my different models. Which is clearly stupid. I figured I needed a helper (module?) and use this helper I my models. But I can''t seem to find anyway of helpers for models, only

I have a simple database: a list of manufacturers (parent) and the parts (child) for the manufacturer. >From scaffold, I have a ?show? view listing manufacturers. I modified this view to list the parts for the manufacturer. I also have a link to create a new part. This causes the controller to display a new view to create a new part for the manufacturer. So creating the part is AOK,

...service so I''m using @companies = Service.find_by_name(''servicename'').companies. But in the development log, rails appears to be making 2 sql calls - one to find the id of the service and a 2nd to find the companies by that id. How can i reduce it to one sql call ? _Tony -- Posted via http://www.ruby-forum.com/.

Hi! If i have Image class and i''d like to add ''create_thumbnail'' method to it, which will later be called from product controller, where to put this method and how to call it?

DB field names: If I have a table that references 2 or more separate users from my users table, is there a recommended naming convention for this situation? In my case, I have 3 users associated with a record in my projects table: requester_user_id created_by updated_by I could name one of them "user_id", and then projects.user would work I guess, but wouldn''t work

We have tables Users and Communities linked by has_an_belongs_to_many. The join table Communities_Users has additional fields [ is_active, is_blocked, join_date] etc. These are populated using @user.push_with_attributes(:is_active => true,...). Later on how do we update or retrieve the attributes in the link table for a given user or a community with doing it explicitly using SQL? Thanks,
