Datamapper fails in Rails3 with jRuby

Reported by Juanma Cervera | March 31st, 2010 @ 05:48 AM | in 1.0.0

The edge version of Datamapper fails with Rails3 and jRuby.

After the update of the gems of Gemfile with jruby -S bundle install, I get this error:

I don know if this is important but I am getting this warning when I do
jruby _S bundle install

Installing dm-core (0.10.3) from git://github.com/datamapper/dm-core.git (at master)

dm-core at /home/jmcervera/.bundle/jruby/1.8/bundler/gems/dm-core-37b4bd22b9e3842977cf83d32baba459607e900a-master did not have a valid gemspec.
This prevents bundler from installing bins or native extensions, but that may not affect its functionality.
The validation message from Rubygems was:
["lib/dm-core/transaction.rb", "spec/public/transaction_spec.rb"] are not files

Juanma,

I don't have any ideas yet what's causing your errors, but I'm pretty sure they weren't related to the fact that dm-core's gemspec was out of sync. I pushed a fix for that to dm-core but I doubt that it'll change things for you. I will try to dig at the root of your problem but any additional hints you can give me (maybe a standalone script to reproduce the error?) would really help me

I'm sorry for being so late at responding.
I have just update to rails3-beta2 and try to use your template for generation of new app and I am getting the same errors.

You can see the console log here
https://gist.github.com/e266f14c5c3930992c2b

I will try to use the gemset feature of rvm and try to use a new fresh environment for the tests.
It might be something weird and messy with my installed gems.

There is no way to have jruby, rails3 and datamapper working for me.
I am using rvm to manage my ruby installation and I have try using new and blank gemsets for installing again all the gems, and even reinstalle completely the jruby environment. And I am having the same error.
Even when I generate a new app from scratch with your template.

It looks like in this specific case, Module#undef_method works differently in MRI as compared with JRuby. In MRI it accepts an Array with 0 or more method names, while in JRuby it accepts only a single method name.

Since the documented API is to accept only a single method, I am going to change DM to match. I will update this ticket when the commit is ready.

(from [7552a8b2d3ab25e5d7b7e7e4a57f8f7a984e4b53]) Fixed invalid usage of Module#undef_method
- In MRI Module#undef_method accepts 0 or more method names, and removes them all. In JRuby it accepts only 1 method name. The documentation shows that only 1 method name should be provided, so JRuby matches the docs, while MRI has a much looser contract.
DM was using the MRI API, but this has been changed to match the documented behaviour, and should work in JRuby.
