I have also read that Pessimistic Locking is now baked into ActiveRecord in Edge Rails. I have tried Rails 1.1.2 and 1.1.4 and that doesn''t seem to be the case. Any idea when

Hi guys, I must be missing something obvious with pessimistic locking. Here is what I do (Rails 2.3, mySQL): In my Foo model: def test Foo.transaction do lock = UpdateLockForFoo.find_by_foo_id(self.id, :lock => true) sleep 30 end end For each Foo model, I have an UpdateLockForFoo. This "lock" needs to be acquired before doing any changes to Foo. I believe it works,

Hello to everyone, I have a problem that is giving me a headache, and trying to do a project in Ruby on Rails and I need to connect with a Data Base that is en Postgres, the truth is that I didn’t think that it was so hard to connect a DB with postgres because I was working with Msyql and everything was easy.

Due to the foolish implied assumption that there''d never be a revision to activerecord library, the Composite Primary Key code promptly broke for anyone who updated their apps to Rails 1.1.6 (with its activerecord-1.14.4) Now the gem dependencies are fixed and your legacy databases are free to wield composite primary keys without fear again.

When I make an empty Rails web application, and go through the steps to create/include a database, and scaffold, mongrel_rails start (or ruby script/server) works just fine. However, I attempted this with a pre-existing web app and I got some errors. First, I gathered the app''s folder (checked the contents, it has all the folders plus one extra: components) and placed it under ruby/

We spent a big chunk of yesterday hunting down a strange bug in one of our rails apps and created a test project to try out different theories on what was going on. The result so far is a very small test case app that perfectly reproduces the problem. The question is, is there anything *wrong* with what we''re doing here, or is it a problem with ActiveRecord? We''re on rails

Basically, how do I make sure that a specific controller action gets executed by only one mongrel server at one time? I obviously cannot use Mutex::synchronize, because we''re talking about different processes. I looked into using optimistic and pessimistic locking. I
