There is some documentation missing, i'm working on it!

Articles in this wiki provide in-depth information on Cuba, Lore and related projects, including their usage. Here is a list of all articles.

• Lore's official project page: http://lore.rubyforge.org
• Lore API documentation: http://lore.rubyforge.org/doc

Cuba will be renamed to and released as "beamr application framework" on rubyforge. In tutorials in this wiki, you would have to replace "Cuba" by "Beamr", but i will change this as soon as the first release is out.

Download Lore

Via svn:

svn checkout svn://rubyforge.org/var/svn/lore

Install Lore

You can checkout Lore's trunk (svn checkout svn://rubyforge.org/var/svn/lore/trunk), or install it via rubygems (recommended):

gem install lore

For the brave: There is also svn://rubyforge.org/var/svn/lore/branches/next, the work in progress on lore's upcoming release. Stuff in this branch is *not* guaranteed to be stable, so be sure to run at least the test suite (ruby dev/test/ts_lore.rb) before even trying it, and do not use it for production.

Defining models looks like this:

# File: my_app/models/my_model.rb
require 'lore/model' 
class MyModel < Lore::Model
  table :mymodel, :public             # table name and schema
  primary_key :key_a, :key_a_id_seq   # Primary key name and its sequence, if required
  primary_key :key_b, :key_a_id_seq   # Another primary key name and its sequence, if required
# ...
end

To use models defined with Lore, you need a procedure like

require 'lore/connection'
logins = { :your_db_name => [ 'user', 'pass' ] }
Lore.setup(:logins => logins)
Lore::Context.enter :your_db_name

# You can load your models now: 
require 'my_app/models/my_model.rb'

# Set up caching, optional: 
Lore.enable_mmap_cache
require 'lore/cache/mmap_entity_cache'
Table_Accessor.use_entity_cache Lore::Cache::MMap_Entity_Cache

# You can access your data now: 
MyModel.find(5).with(MyModel.some_attribute.ilike('%foo%').entities

Feel free to add your (working) example code or complete the tutorials by features they don't cover yet.

But don't post bug complains or questions on the framework and/or API in this wiki!

Send your questions on Cuba, Lore and anything about it to me, or even better: Post a request at rubyforge.
