similar to: Anyone had success with other ORMs?

Hi, Does anyone know of an R ORM (Object Relational Mapper)? I'm thinking of something similar to sqlalchemy (http://www.sqlalchemy.org/). Alternatively or additionally, can people offer suggestions about managing relational databases from R. I'm currently using postgresql, but would like a flexible solution that works across different databases, hence the enquiry about ORMs. Please

Are there any plans to move the schema definition from migrations to the model, where it should be? Like og does, which I think is used by the ruby Nitro framework... ObjectGraph: http://www.rubygarden.org/index.cgi/Libraries/og_tutorial.rdoc Example code: [code] class Post property :title, String, :sql => ''VARCHAR2(32) NOT NULL'' property :body, String property

What is the best way of checking this? I have 3 tables: groups users group_members class GroupMember < ActiveRecord::Base belongs_to :group belongs_to :user validates_uniqueness_of :user_id, :scope => "group_id" Then I want a method here that checks if a given user is a member of a given group. What is the right way of doing that? def

I''m trying to run on trunk. When I run "rake -T" I get an error: undefined local variable or method `full_config'' for Merb::Orms::Sequel:Module I''m not 100% sure that I haven''t messed something up, so I hesitate to cry "bug" without checking with everyone. Is anyone else seeing this? P.S. I''m running merb trunk installed as a gem,

I''m a Django/Catalyst user that''s evaluating Rails ... I need a Ruby framework, and I''m trying to see if learning Rails is worth it or I should just go for Sinatra + various libs available. Django has a couple of things I like ... 1) the Forms API In Django I like that it''s being decoupled from models ... form objects have fields with validation rules that

=== 1. Camping on Rack === I''ve just finished rewriting Camping to use Rack in the "core". I got rid of (a little less) than 1kB in camping.rb and removed lots of un-necessary files (lib/server/*.rb, fastcgi.rb & mongrel.rb). bin/camping does now only provide WEBrick, Mongrel and console-support and should only be used in development. It uses Rack::ShowExceptions to catch

Daniel, Tobias, Renato and myself have been looking a little bit at the potential underlying reason for why http://llvm.org/perf/ is instable, and have found some clues. I want to share them here to give people with more experience in the frameworks used by LNT (flask, sqlalchemy, wsgi, .) a chance to check if our reasoning below seems plausible. Daniel noticed the following backtrace in the

Hi, when I define a db column to be non-nullable or of length 20 or as numeric, I would expect rails to validate that, but that doesn''t seem to be the case. Any idea why that is? The metadata is accessible, at least in the mysql case. I am using rails 1.0 with mysql 5. Cheers, Mariano

Hello Railists, I have a piece of Ruby on Rails code that has a complex SQL query (well, not that complex, but as far as I know beyond the ORM capabilities) and for my taste it has too many strings and harcoded values. I''d like to improve it as much as possible, so my question is open ended, what else can I do to improve it? Some particular issues I have - Is there a way to get a table

= About Ackbar Ackbar is an adapter for ActiveRecord (the Rails ORM layer) to the KirbyBase pure-ruby plain-text DBMS. Because KirbyBase does not support SQL, joins or transactions, this is not a 100% fit. There are some changes to the ActiveRecord interface (see below), but it may still be useful in some cases. = URIs Ackbar: http://ackbar.rubyforge.org KirbyBase:

Guys, I''m designing an application currently that will ultimately be implemented in either Rails or php5 (most likely Rails). While I''ve coded many PHP (pre-5) applications in the past, OO support was so weak that my OO designs were never truly divorced from the limitations of the language, thus I never had to consider this problem. The question is: how does Rails (and how do

In Rolling with Ruby on Rails tutorial - http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html - I saw that to introduce a new element to my domain, I needed to define it in a table, generate a model element with a similar name and the class would autoamtically take the attributes from the table definition. Is it possible to do this in the other direction... i.e to take the class diagram

I hope this isn''t too rambly. This is sort of a brain dump of a subject I''ve been thinking about for months as I''ve used RSpec. Let''s say we''ve got a simple query method, that will find all the users in the DB older than 18. Our model could look like class User < ActiveRecord::Base def self.find_older_than(age) find :all, :conditions =>

Hello, I just did a "gem update" on my server updating to the latest version. After this none of my scripts work. In apache error log I get: FastCGI: comm with (dynamic) server "/home/user/public_html/dispatch.fcgi" aborted: (first read) idle timeout (30 sec) My only guess is that the problem is related to the fastCGI binding but I have no idea what to look for.

Hey, I''m working on a project, and mongrel may be part of the stack, but I''ve got some more general questions and ideas I''m hoping to run by this list. The people on this list have a broader knowledgebase and more experience than any place else I know - plus a general friendliness and willingness to help!

Since there are so many efforts at the moment to port restful_authentication I figured I''d put a repo up so that it can be a collaborative effort. You can pick up a copy of the repo at git clone http://snatcht.com/git/merbful_authentication.git at the moment the app is in a branch. Not in the master. get the branch by git checkout -b remote/initial origin/inital_repo At the moment

Hi people, just thought I''d mumble out my thoughts on merb''s apps directory structure and config concepts and see what other people are feeling... the app dir: mvc/application is layed out as expected....maybe without the mailer by default (another discussion) the config dir: I really think that it''s confusing to have such a mixture of ways to configure some
