I'm trying to build a site with RoR on Google App Engine. I'm using the google-appengine gem (http://appengine-jruby.googlecode.com) and following the instructions in (http://gist.github.com/268192). The problem is that I can't submit ANY form!
I've already tried this in two diferent clean Win 7 Pro envs and the result is the same.
After install Ruby 1.8.6 (One-Click Installer):
1. gem update --system
2. gem install rails
3. gem install google-appengine
4. gem install rails_dm_datastore
5. gem install activerecord-nulldb-adapter
6. curl -O http://appengine-jruby.googlecode.com/hg/demos/rails2/rails2_appengine.rb
7. ruby rails2_appengine.rb (previously downloaded)
8. rails myproj
9. chmod myproj
10. ruby script/generate dd_model MyModel f1:string f2:float f3:float f4:float f5:integer f6:integer f7:integer -f
11. ruby script/generate scaffold MyModel f1:string f2:float f3:float f4:float f5:integer f6:integer f7:integer -f --skip-migration
12. dev_appserver.rb -p 3000 .
At this point, I manually test the scaffold in (http://localhost:3000/my_models). The index is OK, then I create a new registry with the generated form, everything's fine, but when I try to create a second one, I get a "java.lang.RuntimeException: DummyDynamicScope should never be used for backref storage" in the console.
As far as I read this is a won't-fix behavior in JRuby 1.4.1, but it's converted to a debug only warning in 1.5.0, so I proceed to install the pre release.
13. gem install appengine-jruby-jars --pre
With this, that exception is solved and everything works great... until I move the project to the GAE server.
14. ruby appcfg.rb update .
And now, in (http://myproj.appspot.com/my_models), again, the index is fine, also the new form, but in the moment that I submit it with valid data, I get a 500 error: "java.lang.IllegalAccessException: Reflection is not allowed on public int".
As I said, this behavior is not present in the local SDK.
In both cases, I'm completely unable to post anything.
This is what I have right now in the GAE environment:
