data_fabric's Issues

data_fabric 1.3.3 not working with rails 3.1.1

I tried to use data_fabric with rails 3.1.1 but getting error as.... uninitialized constant DataFabric::ConnectionProxy::RAILS_ENV.
While the data_fabric development i.e. https://github.com/bpot/data_fabric.git. is working with rails 3.1.1. But It gives error while executing create statements from the migration file.

Release new version to RubyGems.org

I've been using "version 1.4.0" for almost a year now and it would be nice to finally kill that last github URL in my Gemfile.

Would it be possible to lock down a release and publish it to RubyGems?

data_fabric causing error to resque-mailer

I am using data_fabric from master branch for database replication and resque mailer for batch email processing. I found that data_fabric is causing below error to the resque-mailer. This error stops the processing of resque mailer and it usually occurs immediately after sending the first mail

PGError: ERROR: prepared statement "a3" already exists
: SELECT DISTINCT(attr.attname)
FROM pg_attribute attr
INNER JOIN pg_depend dep ON attr.attrelid = dep.refobjid AND attr.attnum = dep.refobjsubid
INNER JOIN pg_constraint cons ON attr.attrelid = cons.conrelid AND attr.attnum = cons.conkey[1]
WHERE cons.contype = 'p'
AND dep.refobjid = $1::regclass

Would you please help me out to resolve the above issue?

Note: The same type of issue I faced earlier and I resolved it using the code mentioned in below URL.
