Hi all,

            Got struck up with this. Please help.

=20

The actual requirement is that I am trying to generate a model diagram
thru the railroad which I have installed in my machine. I use both
oracle and postgre db's in the db connection (database.yml file).=20

"puredisk_development:

  adapter: postgresql

  database: ca

  port: 10085

  username: ***

  password: ***

=20

reporting_development:

  adapter: oracle

  username: ***

  password: ***

  database: ***

"

The error which I am getting when I am running the command "railroad -M
-v -o models" is=20

This "pd.rb" in the error uses the postgre db conection.

The contents of the pd.rb file are=20

=20

"

class PD < ActiveRecord::Base

  connection =3D "puredisk_#{ENV['RAILS_ENV']}"

  establish_connection connection.to_sym

end

=20

class PD::Policy < PD; set_table_name 'policy'; end

class PD::Dsinpolicies < PD; set_table_name 'dsinpolicies'; end

class PD::Dataselection < PD; set_table_name 'dataselection'; end

class PD::Agent < PD; set_table_name 'agent'; end

class PD::Job < PD; set_table_name 'job'; end

class PD::Policyrun < PD; set_table_name 'policyrun'; end

class PD::Dstemplate < PD; set_table_name 'dataselectiontemplate'; end

class PD::Policytype < PD; set_table_name 'policytype'; end

"

And the rails_env is "development"

=20

Thanks in advance ..
