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

The contents of the pd.rb file are=20

"

class PD < ActiveRecord::Base

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

establish_connection connection.to_sym

end

=20

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

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

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

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

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

And the rails_env is "development"

Hi all,

Got struck up with this. Please help.



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).



"puredisk_development:

adapter: postgresql

database: ca

port: 10085

username: ***

password: ***



reporting_development:

adapter: oracle

username: ***

password: ***

database: ***

"



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

The contents of the pd.rb file are



"

class PD < ActiveRecord::Base

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

establish_connection connection.to_sym

end

Do you have an environment called 'development' in database.yml? It
seems you have reporting_development and puredisk_development but not
development.

That said, I think for one of my projects, I had some problems with
railroad trying to resolve class name because my file names didn't seem
to match the convention... I think my table was called TTFiles and my
model was TtFile and the file name was tt_file.rb - and it all didn't
add up to Railroad properly at that time. I don't know if the problem
you are seeing is because it expects your class to be Pd (not PD)?

Hope this helps.

Cheers,
Mohit.

It looks like it is looking for a class called Pd and not PD.

Try "class Pd < ActiveRecord::Base".
