I''m digging into rails source code. But I''ve got a problem in undestading actionrecord::base source code which is connection_specification.rb. In the body of establish_connection method, def self.establish_connection(spec = nil) case spec when nil raise AdapterNotSpecified unless defined? RAILS_ENV establish_connection(RAILS_ENV)

Hi, My application spans 2 (or more) databases for some very specific reasons... My models are working fine, even dynamically establishing connections as needed at runtime, and spanning relationships across the databases (which really impressed me). The problem is, I can''t seem to force Units for these models (that use a secondary db) to load their fixtures into and use the

Hello, I have an application that access two different DBMS - Firebird and Postgres. So far, that''s ok. The problem is, depending on the customer logged, a different database (Firebird) must be selected. To make the things clearer: Postgres: 1 database shared by all customers with these tables: - user - vehicle - driver Firebird: several databases with different names and identical

Hi all - I have a need to have my models write to one database and read from another. From what I''ve read, Rails doesn''t do this out of the box.

I know this isn''t Python, but I''d like to get a view on the ''one obvious'' way to set up an SQLite (or other) database and its location per-app. I''ve got a bit lost with the Camping 2 changes and various code snippets I have kicking around. 1. is it best to set up the DB creation/connection: 1.1 at the end of the app

Hi, I really need help to understand what is happening while Rails connect to a database, (we area actually using postgresql, so my example will be with postgresql) What I understand is Rails is able to connect to different DB. Actually, this is what we want, and we have made some tests, everything is juste fine. However, all these tests lead us to some important questions that we did find the

Hi, I have a legacy database ''old'' and a new database ''new'' which rails uses. I set up models using old with establish_connection(old), and this works well, except for include: class OldModel < ActiveRecord::Base establish_connection(old) end class NewModel < ActiveRecord::Base has_one :old_model end a = OldModel.find :first NewModel.find(:all,

In my app, for three models: foo,bar and baz, the database connection is made to a different database and hence in model code: class Foo < ActiveRecord::Base establish_connection :diff_database end class Bar < ActiveRecord::Base establish_connection :diff_database end class Baz < ActiveRecord::Base establish_connection :diff_database end Now, the problem is, if is use the above

I have tried for several hour to get a mysql db connection to work, but have failed so far: This is a cpanel server running Mysql 4.1.19, fcgi with apache.

I am using locomotive for development. My app uses dual databases and hence I have a model that uses a different establish_connection to connect to the db. It seems that locomotive does not support this. Am I correct? If so, does anyone have a different approach to achieve this? thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed

Hello all. Due to the mistakes of the company before I joined ;) I am stuck with a multiple database setup. I am planning on parsing the REQUEST_URL to decide which controller is being accessed and basing the establish_connection on that. Before I go messing around with regexps I was wondering if rails has a built in function for parsing URLS. I have googled around a bit and seen net/http

HI Guys, I recently tried VERY hard to override the database configuration bassed on ENV vars or actual API calls. This task is almost next to impossible. I know that the database.yml file is parsed as ERB but that is sane for simple ENV replacement if you want to actually change which database adaptor it is (requires extra config/params) it becomes messy. I found

Hello all. I am currently running a very simple ruby app. It connects to an Oracle server using the OCI8 adapter. I have two controllers, each one connects to a different schema on the server, I looked at the WIKI that had details of multiple database connections (http://wiki.rubyonrails.com/rails/pages/HowtoUseMultipleDatabases), I moved the code from the application controller into each

Hi, I read the example in http://wiki.rubyonrails.com/rails/pages/HowtoUseMultipleDatabases, it show us how to connect to other database, each time we start a new action, however, this doesn''t work while you try to connect to two different database within the same action. SO I wonder is it possible to bind to two or more database within the same action???? Thanks you very much Saiho

Hi, Should I be able to use the Webrick postamble instead of using .campingrc, to tell Camping I want to use mysql? It doesn''t seem to be working for me. It does work however, when I''m using FastCGI (establish_connection :adapter => ''mysql''). James
