DataMapper, JRuby and sqlite3 error
Reported by Łukasz Adamczak | August 28th, 2009 @ 08:23 AM
I'm trying to get JRuby+DataMapper combo work with sqlite3 database.
I have this script:
require 'rubygems'
require 'dm-core'
require 'pp'
DataMapper.setup(:default, "sqlite3:///Users/Czak/tmp/datamapper/development.sqlite3")
class Event
include DataMapper::Resource
property :id, Integer, :serial => true
property :title, String
property :description, Text
end
# Just get an item
pp Event.first
It works perfectly under MRI Ruby 1.8.7, but fails under JRuby 1.3.1. The error is:
/opt/jruby-1.3.1/lib/ruby/gems/1.8/gems/dm-core-0.9.11/lib/dm-core/adapters/data_objects_adapter.rb:68:in `read_one': (sql_state=null) column -1 out of bounds [1,2] (Sqlite3Error)
from /opt/jruby-1.3.1/lib/ruby/gems/1.8/gems/dm-core-0.9.11/lib/dm-core/adapters/data_objects_adapter.rb:173:in `with_connection'
from /opt/jruby-1.3.1/lib/ruby/gems/1.8/gems/dm-core-0.9.11/lib/dm-core/adapters/data_objects_adapter.rb:61:in `read_one'

from /opt/jruby-1.3.1/lib/ruby/gems/1.8/gems/dm-core-0.9.11/lib/dm-core/model.rb:267:in `first'
The current gems installed for JRuby:
addressable (2.0.2)
data_objects (0.9.12)
dm-core (0.9.11)
dm-migrations (0.9.11)
do_jdbc (0.9.12)
do_sqlite3 (0.9.12)
jdbc-sqlite3 (3.6.3.054)
I can't tell from the documentation if JRuby is or is not supported, so I'm submitting here.

Sorry about the formatting, it seems I can't update it now.

- State changed from “new” to “not-applicable”
I'm going to mark this as not-applicable for the time-being, as JRuby support in 0.9.12 was not complete and we did not have all of our spec suite passing at the time of release.
Pending the next release, try "edge" DataMapper: http://gist.github.com/159270
