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 ActiveRecord::Base.establish_connection() to connect to our database, the function

I'm planning to add multiple-database support for searches to my "Xappy" python wrapper (more on this wrapper later, but for now, see http://code.google.com/p/xappy for details). This is reasonably straightforward, because Xapian supports this nicely: except that "Xappy" generates a "fieldname->prefix" mapping automatically. The prefix which corresponds

Hello, guys. Q1. now I have load all the docid and its document data into a dictionary for faster loading data instead of calling Xapian::MSetIterator i; i.get_document().get_data(); but I was happened to discover that the dictionaries got by such two method were different: both methods use DB1, DB2 method 1: Xapian::Database db = Xapian::Database(the path of DB1); Xapian::Database db2 =

Hi all, I''m thinking of useing sub-domains as account keys, something I''ve played with previously. I have accounts and users, fairly standard, except that users can belong to many accounts, and accounts can have many users. So I figure I need to have an area on the main domain, that allows users to view their account memberships and things. Sort of like a dashboard for each

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: unless Componentlog.connected? establish_connection( :adapter => "oci", :database =>

From the documentation I've read, omega can read from multiple databases, but I'm not sure how to go about this. I have three databases created using omindex, currently located at /var/lib/xapian-omega/data/share, /var/lib/xapian-omega/data/users, and /var/lib/xapiax-omega/data/management The quickstart guide says that in omega.conf database_dir should point to the directory

Hi everybody, I just started thinking about a project and am seeking some help regarding its design.
