• Postgresql fails to start on Ubuntu 10.04.4 LTS

  - by cancerballs

  I installed postgresql 9.2 from add-apt-repository ppa:pitti/postgresql using apt-get install postgresql-9.2 At the end of the install and every time I try to launch postgresql by using the following command /etc/init.d/postgresql start or service postgresql start I get this error: Error: could not exec /usr/lib/postgresql/9.2/bin/pg_ctl /usr/lib/postgresql/9.2/bin/pg_ctl start -D /var/lib/postgresql/9.2/main -l /var/log/postgresql/postgresql-9.2-main.log -s -o -c config_file="/etc/postgresql/9.2/main/postgresql.conf" : [fail] invoke-rc.d: initscript postgresql, action "start" failed. dpkg: error processing postgresql-9.2 (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: postgresql-9.2 E: Sub-process /usr/bin/dpkg returned an error code (1) I have tried everything found here: How to thoroughly purge and reinstall postgresql on ubuntu and here: Eliminating non working postgresql installations on ubuntu 10-04 and starting af. I have also done dpkg -P --force-remove-reinstreq postgresql-client-9.2 in my attempt to remove everything postgres related from my server. After removing postgresql I have used dpkg --get-selections | grep postg To be sure there is nothing left and I can do a clean install. I have also made sure that the files and folders mentioned in the error message have the right permissions. The /var/log/postgresql/postgresql-9.2-main.log file is empty. I have tried installing every postgresql version from 8.3 to 9.2 and I get the same error on every time. I once managed to compile postgresql from the source provided on their website but then I encountered weird errors with psycopg2 so I figured I'd install postgresql this way and avoid those errors. Also when I type apt-get install postgresql it by default tries to install the 8.3 version even when I can find the package by typing apt-get install postgresql-9.2.

• Postgresql has broken apt-get on Ubuntu

  - by Raphie Palefsky-Smith

  On ubuntu 12.04, whenever I try to install a package using apt-get I'm greeted by: The following packages have unmet dependencies: postgresql-9.1 : Depends: postgresql-client-9.1 but it is not going to be instal led E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a so lution). apt-get install postgresql-client-9.1 generates: The following packages have unmet dependencies: postgresql-client-9.1 : Breaks: postgresql-9.1 (< 9.1.6-0ubuntu12.04.1) but 9.1.3-2 is to be installed apt-get -f install and apt-get remove postgresql-9.1 both give: Removing postgresql-9.1 ... * Stopping PostgreSQL 9.1 database server * Error: /var/lib/postgresql/9.1/main is not accessible or does not exist ...fail! invoke-rc.d: initscript postgresql, action "stop" failed. dpkg: error processing postgresql-9.1 (--remove): subprocess installed pre-removal script returned error exit status 1 Errors were encountered while processing: postgresql-9.1 E: Sub-process /usr/bin/dpkg returned an error code (1) So, apt-get is crippled, and I can't find a way out.

• Problem with diacritics on psql 9.0 (PostgreSQL)

  - by Gaks

  I have two instances of PostgreSQL installed on my server: 8.3 and 9.0. There seams to be some problem with Polish diacritic characters (like óleaszzc) on postgresql 9.0 client - psql. When I connect to DB (either 8.3 or 9.0) with psql 8.3 - I can type all diacritics on the terminal without any problems: www:/tmp# sudo -u postgres /usr/lib/postgresql/8.3/bin/psql -q postgres=# ólscn However, when I connect to the same DBs with psql 9.0 client - I can't type diacritics on the terminal anymore: www:/tmp# sudo -u postgres /usr/lib/postgresql/8.3/bin/psql -q Here are some encoding settings: www:/tmp# sudo -u postgres /usr/lib/postgresql/9.0/bin/psql -q -c "show client_encoding" client_encoding ----------------- UTF8 (1 row) . www:/tmp# sudo -u postgres /usr/lib/postgresql/8.3/bin/psql -q -c "show client_encoding" client_encoding ----------------- UTF8 (1 row) . www:/tmp# sudo -u postgres /usr/lib/postgresql/9.0/bin/psql -q -l List of databases Name | Owner | Encoding | Collation | Ctype | Access privileges ---------------------+--------------+----------+-------------+-------------+----------------------- postgres | postgres | UTF8 | pl_PL.UTF-8 | pl_PL.UTF-8 | . www:/tmp# echo $LANG pl_PL.UTF-8 It looks like DB/cluster configuration doesn't matter - if psql 8.x on terminal works fine and psql 9.x does not. Any idea how to fix that?

• rails gem permissions problem (tabs on rails)

  I'm having trouble running a gem, tabs on rails -v=1.3.2, in my rails 2.3.8 app. The gem is installed locally (Ubuntu 10.10) and I have config.gem "tabs_on_rails", :version="1.3.2" in environment.rb.

Any help is very much appreciated!

• Ruby on Rails: url_for :back leads to NoMethodError for back_url

  - by Platinum Azure

  Hi all, I'm trying to use url_for(:back) to create a redirect leading back to a previous page upon a user's logging in. I've had it working successfully for when the user just goes to the login page on his or her own. However, when the user is redirected to the login page due to accessing a page requiring that the user be authenticated, the redirect sends the user back to the page before the one s/he had tried to access with insufficient permissions. I'm trying to modify my login controller action to deal with the redirect properly. My plan is to have a query string parameter "redirect" that is used when a forced redirect occurs. In the controller, if that parameter exists that URL is used; otherwise, url_for(:back) is used, or if that doesn't work (due to lack of HTTP_REFERER), then the user is redirected to the site's home page. Here is the code snippet which is supposed to implement this logic: if params[:redirect] @url = params[:redirect] else @url = url_for :back @url ||= url_for :controller => "home", :action => "index" end The error I get is: NoMethodError in UsersController#login undefined method `back_url' for # RAILS_ROOT: [obscured] Application Trace | Framework Trace | Full Trace

• How can I get access to password hashing in postgresql? Tried installing postgresql-contrib in ubun

  - by Tchalvak

  So I'm trying to just hash some passwords in postgresql, and the only hashing solution that I've found for postgresql is part of the pgcrytpo package ( http://www.postgresql.org/docs/8.3/static/pgcrypto.html ) that is supposed to be in postgresql-contrib ( http://www.postgresql.org/docs/8.3/static/contrib.html ). So I installed postgresql-contrib, (sudo apt-get install postgresql-contrib), restarted my server (as a simple way to restart postgresql). However, I still don't have access to any of the functions for hashing that are supposed to be in postgresql-contrib, e.g.: ninjawars=# select crypt('global salt' || 'new password' || 'user created date', gen_salt('sha256')); ERROR: function gen_salt(unknown) does not exist ninjawars=# select digest('test', 'sha256') from players limit 1; ERROR: function digest(unknown, unknown) does not exist ninjawars=# select hmac('test', 'sha256') from players limit 1; ERROR: function hmac(unknown, unknown) does not exist So how can I hash passwords in postgresql, on ubuntu?

• Can't store array in json field in postgresql (rails) can't cast Array to json

  - by Drew H

  This is the error I'm getting when I run db:migrate rake aborted! can't cast Array to json This is my table class CreateTrips < ActiveRecord::Migration def change create_table :trips do |t| t.json :flights t.timestamps end end end This is in my seeds.rb file flights = [{ depart_time_hour: 600, arrive_time_hour: 700, passengers: [ { user_id: 1, request: true } ] }] trip = Trip.create( { name: 'Flight', flights: flights.to_json } ) For some reason I can't do this. If I do this. trip = Trip.create( { name: 'Flight', flights: { flights: flights.to_json } } ) It works. I don't want this though because now I have to access the json array with trip.flights.flights. Not the behavior I'm wanting.

• Strange permission errors in new PostgreSQL installation

  - by Bart van Heukelom

  A freshly installed PostgreSQL (with configuration overwritten) won't start: $ sudo service postgresql start * Starting PostgreSQL 9.1 database server * Error: could not read /etc/postgresql/9.1/main/postgresql.conf: Permission denied Looks like it should be able to read it though: $ ls -l postgresql.conf -rw------- 1 postgres postgres 19450 2012-06-14 10:07 postgresql.conf But fine, I'll add chmod +r it to test if that works. $ sudo chmod +r postgresql.conf $ sudo service postgresql start * Starting PostgreSQL 9.1 database server * The PostgreSQL server failed to start. Please check the log output: Error: Could not open log file /var/log/postgresql/postgresql-9.1-main.log Huh? $ ls -l /var/log/postgresql/ total 4 -rw-r----- 1 postgres adm 827 2012-06-14 10:07 postgresql-9.1-main.log I don't get it. What can be wrong here? This used to work before. Can I maybe monitor what process attempts to open the file? It's Ubuntu 11.10 on EC2, using Chef. For completeness, here's the recipe: # Install PostgreSQL package "postgresql-9.1" # Stop server service "postgresql" do action :stop end # Overwrite configuration (setting data dir) template "/etc/postgresql/9.1/main/postgresql.conf" do source "postgresql-conf.erb" owner "postgres" group "postgres" end # Start server service "postgresql" do action :start end

• How to test Rails 3 Engines with Cucumber & Rspec?

  - by cowboycoded

  I apologize if this question is slightly subjective... I am trying to figure out the best way to test Rails 3 Engines with Cucumber & Rspec. In order to test the engine a rails 3 app is necessary. Here is what I am currently doing: Add a rails test app to the root of the gem (myengine) by running: rails new /myengine/rails_app Add Cucumber to /myengine/rails_app/features as you would in a normal Rails app Require the Rails Engine Gem (using :path=>"/myengine") in /myengine/rails_app/Gemfile Add spec to the root directory of the gem: /myengine/spec Include the fixtures in /myengine/spec/fixtures and I add the following to my cuc env.rb: env.rb: Fixtures.reset_cache fixtures_folder = File.join(Rails.root, 'spec', 'fixtures') fixtures = Dir[File.join(fixtures_folder, '*.yml')].map {|f| File.basename(f, '.yml') } Fixtures.create_fixtures(fixtures_folder, fixtures) Do you see any problems with setting it up like this? The tests run fine, but I am a bit hesitant to put the features inside the test rails app. I originally tried putting the features in the root of the gem and I created the test rails app inside features/support, but for some reason my engine would not initialize when I ran the tests, even though I could see the app loading everything else when cuc ran. If anyone is working with Rails Engines and is using cuc and rspec for testing, I would be interested to hear your setup.

• How to force reload all vendor/plugins in rails 2.3 (development mode)

  - by tsdbrown

  We have an application with a app/model that references another model stored in a plugin. When the app/model level is reloaded on the second and further requests and that relies on our model in vendor/plugins/... (which stays loaded) it fails (can't dup nil class). We've tried setting config.reload_plugins = true in the development.rb but this doesn't seem to do it. Does anybody know a way to handle this?

• Resolving “ssl handshake failure” error in PostgresQL

  - by Mitch

  I would like to connect to my Postgres 8.3 database using SSL from my XP client using OpenSSL. This works fine without SSL. When I try it with SSL (no client certificate), I get the error: error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure I have followed the instructions in the Postgres manual for SSL including creating a self-signed certificate. In my pg_hba.conf there is a line: host dbname loginname 123.45.67.89/32 md5 The version of OpenSSL on the server is 0.9.8g and on the client is 0.9.8j.

• Trying to install postgresql:i386 on 12.04 amd64

  - by tim jackson

  Due to some legacy 32 bit libraries being used in postgresql functions I need to get a 32 bit install of Postgresql on a 64 bit native system. But it seems like there is a problem with the multiarch not seeing all.debs as satisfying dependencies. uname -a: 3.8.0-29-generic #42-precise-Ubuntu SMP x86_64 dpkg --print-architecture: amd64 dpkg --print-foreign-architecture: i386 apt-get install postgresql-9.1: returns postgresql : Depends: postgresql-9.1 but it is nto going to be installed postgresql-9.1:i386 : Depends: postgresql-common:i386 but it is not installable Depends: ssl-cert:i386 but it is not installable Depends: locales:i386 but it is not installable etc .. But I have installed ssl-cert_1.0.28ubuntu0.1_all.deb and locales_..._all.deb andpostgresql-common is an all.deb Does anyone have experience installing 32 bit packages on 64 bit systems that depend on packages that are all.debs. Or has anyone installed 32 bit postgres on 64 bit? Any help appreciated.

• Rails application keeps timing out when attempting to connect to Postgresql DB

  - by Corillian

  I'm hosting a postgresql database on a small windows azure Ubuntu 13.04 VM with a default postgresql.conf. I have a Rails application running on a medium windows azure Ubuntu 13.04 VM. When accessing the postgresql database the rails application is constantly timing out. In its database.yml I have the connection pool size set to 120 and the timeout set to 15 seconds. Despite this my rails logs are full of the following error message: ActiveRecord::ConnectionTimeoutError: could not obtain a database connection within 5 seconds (waited 5.0023203 seconds). The max pool size is currently 120; consider increasing it. My postgresql.conf has a max connection limit of 120, making it any larger prevents the server from being able to successfully restart. I've also made sure that ssl was off in the postgresql.conf per this article but beyond that I have no idea what's going on. My postgresql logs don't contain any info indicating something is going wrong. My website is getting ~1k hits per day so perhaps a small VM instance just isn't powerful enough? I appreciate any assistance! [Edit1] The postgresql database is in a separate cloud service within the same affinity group. For example: db small VM: mydatabase.cloudapp.net (Affinity Group US East) forums medium VM: myforums.cloudapp.net (Affinity Group US East) On the database server I have opened port 5432. The connection to the database server from the forums server is using its hostname. Is it possible that the DNS resolution is what's taking so long?

• Migrate from MySQL to PostgreSQL on Linux (Kubuntu)

  - by Dave Jarvis

  Storyline Trying to migrate a database from MySQL to PostgreSQL. All the documentation I have read covers, in great detail, how to migrate the structure. I have found very little documentation on migrating the data. The schema has 13 tables (which have been migrated successfully) and 9 GB of data. MySQL version: 5.1.x PostgreSQL version: 8.4.x I want to use the R programming language to analyze the data using SQL select statements; PostgreSQL has PL/R, but MySQL has nothing (as far as I can tell). A long time ago in a galaxy far, far away... Create the database location (/var has insufficient space; also dislike having the PostgreSQL version number everywhere -- upgrading would break scripts!): sudo mkdir -p /home/postgres/main sudo cp -Rp /var/lib/postgresql/8.4/main /home/postgres sudo chown -R postgres.postgres /home/postgres sudo chmod -R 700 /home/postgres sudo usermod -d /home/postgres/ postgres All good to here. Next, restart the server and configure the database using these installation instructions: sudo apt-get install postgresql pgadmin3 sudo /etc/init.d/postgresql-8.4 stop sudo vi /etc/postgresql/8.4/main/postgresql.conf Change data_directory to /home/postgres/main sudo /etc/init.d/postgresql-8.4 start sudo -u postgres psql postgres \password postgres sudo -u postgres createdb climate pgadmin3 Use pgadmin3 to configure the database and create a schema. A New Hope The episode began in a remote shell known as bash, with both databases running, and the installation of a command with a most unusual logo: SQL Fairy. perl Makefile.PL sudo make install sudo apt-get install perl-doc (strangely, it is not called perldoc) perldoc SQL::Translator::Manual Extract a PostgreSQL-friendly DDL and all the MySQL data: sqlt -f DBI --dsn dbi:mysql:climate --db-user user --db-password password -t PostgreSQL > climate-pg-ddl.sql mysqldump --skip-add-locks --complete-insert --no-create-db --no-create-info --quick --result-file="climate-my.sql" --databases climate --skip-comments -u root -p The Database Strikes Back Recreate the structure in PostgreSQL as follows: pgadmin3 (switch to it) Click the Execute arbitrary SQL queries icon Open climate-pg-ddl.sql Search for TABLE " replace with TABLE climate." (insert the schema name climate) Search for on " replace with on climate." (insert the schema name climate) Press F5 to execute This results in: Query returned successfully with no result in 122 ms. Replies of the Jedi At this point I am stumped. Where do I go from here (what are the steps) to convert climate-my.sql to climate-pg.sql so that they can be executed against PostgreSQL? How to I make sure the indexes are copied over correctly (to maintain referential integrity; I don't have constraints at the moment to ease the transition)? How do I ensure that adding new rows in PostgreSQL will start enumerating from the index of the last row inserted (and not conflict with an existing primary key from the sequence)? Resources A fair bit of information was needed to get this far: https://help.ubuntu.com/community/PostgreSQL http://articles.sitepoint.com/article/site-mysql-postgresql-1 http://wiki.postgresql.org/wiki/Converting_from_other_Databases_to_PostgreSQL#MySQL http://pgfoundry.org/frs/shownotes.php?release_id=810 http://sqlfairy.sourceforge.net/ Thank you!

• Why am I getting "ArgumentError: wrong number of arguments (1 for 0)" when running my rails function

• Rails 2 support after Rails 3 has been released

  - by J. Pablo Fernández

  Is there some plan or estimate about how long will Rails 2 be supported after Rails 3 has been released? I wanted to ride the wave and move to Rails 3 right away, specially for projects that may take 4 or 6 months to finish (so that they would probably be released with Rails 3.0.0 final) but I've found many things still not working, many basic plugins and gems; so I believe I'm stuck with Rails 2 for now.

• How to extend an 'unloadable' Rails plugin?

  - by Vitaly Kushner

  I'm trying to write a plugin that will extend InheritedResources. Specifically I want to rewrite some default helpers. And I'd like it to "just work" once installed, w/o any changes to application code. The functionality is provided in a module which needs to be included in a right place. The question is where? :) The first attempt was to do it in my plugin's init.rb: InheritedResources::Base.send :include, MyModule It works in production, but fails miserably in development since InheritedResource::Base declared as unloadable and so its code is reloaded on each request. So my module is there for the first request, and then its gone. InheritedResource::Base is 'pulled' in again by any controller that uses it: Class SomeController < InheritedResource::Base But no code is 'pulling in' my extension module since it is not referenced anywhere except init.rb which is not re-loaded on each request So right now I'm just including the module manually in every controller that needs it which sucks. I can't even include it once in ApplicationController because InheritedResources inherites from it and so it will override any changes back. update I'm not looking for advice on how to 'monkey patch'. The extension is working in production just great. my problem is how to catch moment exactly after InheritedResources loaded to stick my extension into it :) update2 another attempt at clarification: the sequence of events is a) rails loads plugins. my plugin loads after inherited_resources and patches it. b) a development mode request is served and works c) rails unloads all the 'unloadable' code which includes all application code and also inherited_resources d) another request comes in e) rails loads controller, which inherites from inherited resources f) rails loads inherited resources which inherit from application_controller g) rails loads application_contrller (or may be its already loaded at this stage, not sure) g) request fails as no-one loaded my plugin to patch inherited_resources. plugin init.rb files are not reloaded I need to catch the point in time between g and h

• Postgresql server will not start

  - by Claudiu

  I'm on Windows 7. I restarted my computer. I then tried to connect to the database and got an error. I don't remember which one in particular but it was some connection issue. I decided to try to restart the server, so I clicked on "Restart server" from the start menu. This blocked. After a few minutes I killed the process and tried again, only to get a "The service is starting or stopping. Please try again later." message. I rebooted the computer again, tried to start again, and got the same error. I killed the pg_ctl process and tried starting it manually, but that didn't work either: C:\Users\DrClaud>cscript "C:\Program Files\PostgreSQL\8.3\scripts\serverctl.vbs" start wait Microsoft (R) Windows Script Host Version 5.8 Copyright (C) Microsoft Corporation. All rights reserved. The PostgreSQL Server 8.3 service is starting................................... ....................................... The PostgreSQL Server 8.3 service could not be started. The service did not report an error. More help is available by typing NET HELPMSG 3534. The start command returned an error (2) Any ideas?

• PostgreSQL 8.4 - Tablespace Optimization

  - by FloE

  I'm currently running a PostgreSQL Database with about 1.5 billion rows / 500 GB of data (including indices). There are several schemata: on for the (read only, irregular changes / updates) 'core-model' and one for every user (about 20 persons). The users can access the core and store data in their own schema, so everything is located in one database. The server runs with CentOS and PostgreSQL 8.4 and is used for scientific studies, exploration etc and is running quite well. These days an upgrade of the DB storage hard disks arrive - all with the same performance as the old ones. I'm looking for the best way to distribute the data on these disks. It would be possible to separate frequently used objects (the core-data) from the user schemata, but I'm not sure if this is really worth the effort. It seems to be a much better idea to move the WAL files (pg_xlog directory) to its own partition. http://www.postgresql.org/docs/8.4/static/wal-internals.html What are your opinions? Are there any tablespace- or partitioning-related performance documentations / benchmarks?

• Writing tests for Rails plugins

  - by Adam

  I'm working on a plugin for Rails that would add limited in-memory caching to ActiveRecord's finders. The functionality itself is mature enough, but I can't for the life of me get unit tests to work with the plugin. I now have under vendor/plugins/my_plugin/test/my_plugin_test.rb a standard subclass of ActiveSupport::TestCase with a couple of basic tests. I try running 'rake test' from the plugin directory, and I have confirmed that this task loads the ruby file with the test case, but it doesn't actually run any of the tests. I followed the Rails plugin guide (http://guides.rubyonrails.org/plugins.html) where applicable, but it seems to be horribly outdated (it suggests things that Rails now do automatically, etc.) The only output I get is this: Kakadu:ingenious_record adam$ rake test (in /Users/adam/Sites/1_PRK/vendor/plugins/ingenious_record) /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -Ilib:lib:test "/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rake-0.8.3/lib/rake/rake_test_loader.rb" "test/ingenious_record_test.rb" The simplest test case looks like this: require 'test_helper' require 'active_record' class IngeniousRecordTest < ActiveSupport::TestCase test "example" do assert false end end This should definitely produce at least some output, and the only test in that file should produce a failed assertion. Any ideas what I could do to get Rails to run my tests?

• Rails 2.3.5 and oauth-plugin

  - by pgb

  I started a rails application from scratch, using Rails 2.3.5, and installed oauth-plugin. The installation was done by running script/plugin install git://github.com/pelle/oauth-plugin.git. Now, when I try to start the server, I get the following errors: => Rails 2.3.5 application starting on http://0.0.0.0:3000 /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:440:in `load_missing_constant': uninitialized constant Rails::Railtie (NameError) from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:80:in `const_missing' from /Users/Pablo/Projects/test.oauth/vendor/plugins/oauth-plugin/lib/oauth-plugin.rb:16 from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in `new_constants_in' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /Users/Pablo/Projects/test.oauth/vendor/plugins/oauth-plugin/rails/init.rb:1:in `evaluate_init_rb' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/rails/plugin.rb:158:in `evaluate_init_rb' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/core_ext/kernel/reporting.rb:11:in `silence_warnings' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/rails/plugin.rb:154:in `evaluate_init_rb' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/rails/plugin.rb:48:in `load' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/rails/plugin/loader.rb:38:in `load_plugins' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/rails/plugin/loader.rb:37:in `each' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/rails/plugin/loader.rb:37:in `load_plugins' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/initializer.rb:369:in `load_plugins' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/initializer.rb:165:in `process' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/initializer.rb:113:in `send' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/initializer.rb:113:in `run' from /Users/Pablo/Projects/test.oauth/config/environment.rb:9 from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in `new_constants_in' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/commands/server.rb:84 from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require' from script/server:3 I can't figure out why this is failing.
