Hi everyone,
I'm in the early stages of using JRuby on Rails to build an
administration webapp for a travel site. So far it's looking
promising, although I've so far spent most of the time by far working
out kinks in the configuration. I need to talk to a MSSQL server using
JNDI, all running on an Oracle app server, and by now it's actually
working out fine (if I disable the Java security manager - I made
another post on that).
Anyway, my present problem is that upgrading to ActiveRecord-JDBC
0.2.4 seems to introduce an error related to aliasing. I have an alias
for the column 'udbyderId', which is called 'udbyderid' in the model
(alias_attribute :udbyderId, :udbyderid).
I should note that this is in the dev environment where I'm not using
JNDI but JDBC and WEBrick instead of Oracle, and MySQL in place of
MSSQL - but, rather impressingly, the error below is the same in both
environments.
Using ActiveRecord-JDBC 0.2.3 my webapp can connect to the database
and show a list of records. Everybody's happy.
Using ActiveRecord-JDBC 0.2.4 in exactly the same configuration gives
the following error:
NameError in Rejsetilbud#index

Should I create a JIRA issue? Can't be that something blatantly
obvious is wrong since it works with the 0.2.3 ActiveRecord-JDBC. Is
there some information I need to include with the issue report, or
have I gone overboard already? :-)
Kind regards,

P. S. The svn:externals property in the rails-integration
samples/helloworld-1.2.3/vendor/plugins directory needs to be updated
following the name change to goldspike. It refers to null and void at
the moment, and so you can't 'svn up' the project.
