data_fabric 1.3.3 not working with rails 3.1.1

[vishakhasawant]

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.

Yup, the RAILS_ENV issue is fixed on master. I hope to push a new version of the gem this week with that fix and 3.2 support. What errors are you seeing from the migration?

Hi bpot,

Thanks for the reply. Below is the error stack-trace I am getting while trying to run migration with model.create statements.

e.g. class User < ActiveRecord::Migration def change create_table :user do |t| t.string :name t.string :email t.string :address
end #data User.create(:name => 'firstname', :email => '[email protected]', :address => 'uk') end

end
