multiple database in the same actions?
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

Extracting a connection out of ActiveRecord::Base
Hi
I''m trying to use the Typo wordpress converter script, but it requires
that the wordpress database is accessible over the connection to the
Typo database.
To get around this, I''m trying to use ActiveRecord::establish_connection
(...) to get a connection object to run the raw SQL queries that Typo''s
wordpress converter uses on. It doesn''t work with Ruby

I really need help to understand what is happening

unless connected? + multiple databases
Hello all.
I am still having fun with multiple databases. In this case it is the
unless connected? statement.
ActiveRecord::Base establishes a connection that is inherited by the
majority of my models. However one Model (Componentlog) that uses a
separate DB is coded as:

How to disconnect to a database????
Hi,
We have experienced some problems with
ActiveRecord::Base class of Ruby-Rails. We are
building a web-application based on the Ruby-rails
framework and the web-application needs to access to
difference databases, so we do not pre-define our
database accesses in the database.yml file. In fact,
we are using the

dynamic setting of username and password in database.yml
Hello
I''ve now read a lot about application-level authentication in Rails, but
I need to do database-level authentication.
The reason is that my database needs to have the current_user (database
current_user, not current_user defined in an ActiveRecord Model) set to
execute triggers for automatically updating audit tables. So it is not
enough to have a session check against a User

How to copy between databases?
I want to copy data from one database to another using rails. But, it seems
that rails only will talk to one database at a time. Is there a way around
this?
Any help would be greatly appreciated.

Howdy.
I''m trying to work with a legacy SQL Server database where some of the
table names have spaces in them.
I''ve done set_table_name "tablename with spaces", but I can''t get
find(:all) to work. I get the following error (because apparently
it''s not putting [ ] around the name as is required for SQL Server for

MySQL has gone away
Hi,
in a production environment we are running into "MySQL server has gone
away" errors (see below) when we call rebuild_index in aaf. This happens
sporadically.
Any suggestions for what might be wrong or workarounds? I guess we try a
reconnect before we call rebuild_index?

Updating multiple databases at the same time
I have an application that is load balanced. I have a master database
which I update once a day. Then I push the raw mysql files to all other
servers so they are the same as the master. This works fine, but there
are a few situations where I need all databases to update in real-time.
What would be the best way to achieve this in rails?
Here is an example of what I am trying to do. I want to

Connection problem with a generic-runtime-built ActiveRecord::Base

I''m trying to create a "runtime-generic" ActiveRecord

Fake ActiveRecord model?
Hi all,
I have a legacy table which I cannot get to work with ActiveRecord (no
ids etc). All I want is to create a class which opens a connection
manually and allows me to execute some plain SQL statements.
What I can''t figure out is how to either build up a connection and
execute queries from a non-AR inherited class, or how to create a
AR-inherited class minus all the AR magic and
