Hi, I''m building a frontend for a legacy schema, with tables like this: CREATE TABLE `types` ( `a_type_cd` varchar(6) NOT NULL default '''', `a_type` varchar(30) NOT NULL default '''', PRIMARY KEY (`a_type_cd`) ); The primary key is specified by the user (not auto-generated), and needs to be updateable.

I have a legacy database with which I need to interface. There are two tables that are joined together by two fields, and neither field is the primary key of its associated table. Is constructing an association between these tables beyond the capability of Rails? -- Posted via http://www.ruby-forum.com/.

OK - I know this has been asked before, but I cannot find it in the archives. Forgive me if I''m creating more noise than I should. I want to know the easiest way to deal with this scenario: I have articles. I have categories for the articles. On the form where you write an article, there needs to be a free-form field to entire the category. The create() method will build the

I''m currently try to push my limits a little bit with some of my unit testing -- trying to avoid saving ActiveRecord objects to the database and take advantage of mock/stub objects. How far should I expect to get in this direction? From what I can tell, ActiveRecord seems to fight me when it comes to associations. In other words, many associations seem to require database queries.

I rememeber seeing an article about how to cope with legacy databases where the primary key is defined as VARCHAR2. I only want read-access to the data. Does anyone have a link to such an article? Or can give advice? -- Posted via http://www.ruby-forum.com/.

Hey folks I am just investigating using Aspects for logging my main Javascript "interfaces". I don''t believe Prototype has any built in capabilities for this but I just thought I''d check and see how people had tackled this before. I am still getting to grips with core JS so apologies if this is easy or obvious.. I am Googling as we speak also.. Cheers Matt

R helpers I am getting to grips with R but came across a small problem today that I could not fix by myself. I have 3 text files, each with a single column of data. I read them in using: myData1<-scan("C:/Program Files/R/myData1.txt") myData2<-scan("C:/Program Files/R/myData2.txt") myData3<-scan("C:/Program Files/R/myData3.txt") I wanted to produce a

Hi all I'm trying to get to grips with this one, but just can't figure it out. I recently acquired some 2nd hand Dell Poweredge 860 servers, and noticed that they have built in remote management interfaces. So, I have setup one, and assigned an IP address to it, but have no idea on how to access it remotely. Google'ing for an answer didn't bring me more than general product

Hello, I have a situation where the foreign key into a table doesn''t correspond to that table''s primary key: my_table ------------- id (pk) name ... other_table -------------- id (pk) my_table_name (fk references my_table(name)) ...

Hi, I'm just coming to grips with "for" looping etc. and have a bit of a problem: I want to generate a sequence which goes 1 2 3 4 5 6 7 8 14 15 16 17 18 19 20 21 26 27 ... i.e. 8 consecutive numbers then 5 missed then the next 8 numbers etc. I was going to do this using the seq() function but couldn't figure out how so I thought I'd try a loop: for (x in seq(1,650,13)) {

Hi all, I''m just getting to grips with rspec, and I''m trying to put together a showy demo. We''re trying to use the (plain text) stories feature, rather than the specs. I''d like to show off a fancy HTML report of the results if possible. So it seems I can do this from the spec command line tool, but I can''t make it work for a story. I''ve got

Announcement: Composite Primary Keys gem now includes support for ActiveRecord Associations. Summary: Composite Primary Keys allows an ActiveRecord to support 2+ primary keys using the set_primary_keys class method. Previous versions provided full CRUD and find support. This latest release provides support for more ActiveRecord magic: associations (has_many, belongs_to, etc) Full report:

Due to the foolish implied assumption that there''d never be a revision to activerecord library, the Composite Primary Key code promptly broke for anyone who updated their apps to Rails 1.1.6 (with its activerecord-1.14.4) Now the gem dependencies are fixed and your legacy databases are free to wield composite primary keys without fear again. Description: Composite Primary Keys

ActiveRecords with composite primary keys now seem to happily support find/create/update/destroy options. Url: http://compositekeys.rubyforge.org Background: Rails/ActiveRecords has long been critised for not supporting legacy databases, especially composite primary keys. This gem extends ARs with this support. Cheers Nic -- Posted via http://www.ruby-forum.com/.
