I have a serialized field called options(of type Hash) in my User model. The options field behaves like a Hash most of the time. When I convert the user object to XML, the 'options' field is serialized as a YAML type instead of Hash. I am sending the result to a Flash client via REST. This behaviour is causing problems at the client si...
Our team is developing a Rails app on MySQL and using config.active_record.schema_format = :sql per The Rails Guides. Naturally, our AUTO_INCREMENT values in development_structure.sql get out-of-sync as we develop in parallel. We know that having different values in our databases for AUTO_INCREMENT is not a technical problem. However, i...
Most of my work in a rails application is done with rails engines. When I develop new applications, it usually use a custom built cms. My CMS was inspired by refineryCMS in that there is a core that lives as a rails engine. Features that make up the application are other rails engines that register themselves with the core. For example t...

Hello, I am trying to update InstantRails, and I did really, really google for any tutorial for it but found none. One site was mentioned to have contained a tutorial but it is not gone http://dwiardiirawan.com/. I know there's this installer available for Windows, but I think one needs to extract a tar file and replace the existing file...
Two apologies in advance. One for trying to fight rails defaults, another for the example in the title, which I think sums up my question better than I can otherwise. Any way to do what I want without having the world collapse on itself? I got as far as putting a to_param in my model, but that doesn't quite go all the way. ...

Now that Rails 3 beta is out, I thought I'd have a look at rewriting an app I have just started work on in Rails 3 beta, both to get a feel for it and get a bit of a head-start. The app uses MongoDB and MongoMapper for all of its models nad therefore has no need for ActiveRecord. In the previous version, I am unloading activerecord in th...
