Rails 3 and ActiveModel

Hi @all!

I want to start a new pet project and use the latest technology out there. For me it means Rails 3 and MongoMapper.

I’ve been trying to use the rails 3 fork which supports activemodel. However I’m suffering from severe lack of documentation.

I has able to setup the project, but now I have some questions: does the rails 3 fork supports generations? I tried to put “g.orm :mongo_mapper” and “g.orm :mongomapper” without any success (it always complains that it doesn’t know the ORM).

Any example out there using the rails 3 fork? Thank you for your help!

Hi Ruben. I'm still working on getting the new generators integrated into my fork of MongoMapper at http://github.com/merbjedi/mongomapper. I'll mainly be using the ones taken from here: http://github.com/indirect/rails3-generators

If you're using MongoMapper, you'll sort of have to get used to the lack of documentation. I tend to have the MongoMapper library tests open in an editor at all times so I can quickly search through them for code examples. The switch to ActiveModel could potentially remove the need to document a huge chunk of functionality (like validations) since you'll be able to use a lot of the core rails docs which seems to be extremely well maintained as of late.

Really though, MongoMapper isn't a terribly complex library. Codebase is well organized and fairly easy to understand. The biggest learning curve I had to overcome was just MongoDB itself and its ruby interface. And for that 10gen has pretty excellent docs. http://www.mongodb.org/display/DOCS/Ruby+Tutorial

I'd recommend getting as familiar as possible with the MongoDB commands and the ruby driver. It makes looking into the mongomapper internals and getting it to do what you need it to do much much easier.

Best of luck

Great answer Jacques.

I second that, John. Good advice, Jacques.

Hi Jackes!

This is always a good advice, and after reading your email and opening mongomapper test suite, it was really a blessing :)

Thank you for your time and help, and keep up the good work!! I will keep a close watch on the rails 3 branch :)

I saw how to get the merbjedi mongomapper working, how do I install
your generators, Jacques?

Sorry, haven't integrated them yet. You might be able to install them directly from the instructions here: http://github.com/indirect/rails3-generators

I still need to dive into the new generators in Rails3. Haven't wrapped my head around it quite yet.

If that's the actual code, might want to correct the example callbacks before_create and before_update ..
