PostgreSQL (Postgres-pr) + Rails = Unexpected EOF error?

ruby-talk
1

I'm running XP, Ruby 1.8.2RC3, Rails 0.8.5, PostgreSQL 8BetaRC3, and
Postgres-pr (new Ruby library).

My problem is that I'm getting an "Unexpected EOF error on client
connection."

Does anyone perchance know what's causing this? It happens both on Webrick
and Apache.

Regards, Abe

P.s. I have not yet successfully completed a connection to the PostgreSQL DB
yet.

Hi David and Michael;

I'm not entirely sure where the problem lies so I thought I'd just ask
both of you if you might know what could be causing the error I'm
getting trying to run a tutorial on Rails. I'm running Rails-0.8.5,
postgres-pr-0.2.1, and a PostgreSQL DB (version 8 RC 3), on Ruby 1.8.2RC3.

The code that evokes the error is as so...

in [todo_controller.rb]

require 'abstract_application'
require 'todo'

class TodoController < AbstractApplicationController
  helper :todo
  scaffold :todo
end
and in [todo_helper.rb]

module TodoHelper
end

and lastly in [todo.rb]

require 'active_record'
require 'todo'

class Todo < ActiveRecord::Base
end
The issued URL looks like: http://localhost/todo/

The error:

TypeError in Todo#index

superclass mismatch for class ParseError

Hm, ParseError is a class in postgres-pr/message.rb. But I don't understand
the error message "superclass mismatch". Can you update to
0.2.2 which puts all stuff into a module PostgresPR. Maybe it was a
namespace issue?

Regards,

  Michael

I had it last night for a bit, it was a bad database.yml setting.
Can you get in with psql?

The following database.yml:

production:
  adapter: postgresql
  database: dbname
  host: db.server
  username: dbuser
  password: dbpass

maps to

psql -U dbuser -h db.server dbname
<enter dbpass when prompted>

If you can't see your tables (type \dt once you're in psql), create them.

Thanks for the helpful instructions Dick. :slight_smile:

I hadn't yet tried getting in with psql, but using what you described I was
able to get in with the settings I have currently established in the
database.yaml file.

Talk about frustrating, I think I'm gonna have to break out my process
viewer so I can see what files this baby touches. UGH.
