Railroad problem

Ruby
1

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: ***

"

The error which I am getting when I am running the command “railroad -M
-v -o models” is

/usr/local/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support
/dependencies.rb:249:in `load_missing_constant’: Expected
config/…/app/models/pd.rb to define Pd (LoadError)

    from /usr/local/bin/railroad:16:in `load'

    from /usr/local/bin/railroad:16

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

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”

Thanks in advance …

Anand.

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,

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

Try “class Pd < ActiveRecord::Base”.
