Question

I have the following code in my seeds.rb file in a jruby 1.6.3 rails 3.1 project which I invoke with rake db:seed

Role.destroy_all
User.destroy_all

["admin", "standard"].each do |role|
  Role.find_or_create_by_name(role)
end

if User.find_by_email("[e-mail]").nil?
  user = User.new
  user.email = "[e-mail]"
  user.password = "Passw0rd"
  user.password_confirmation = "Passw0rd"
  user.role = Role.find_by_name("admin")
  user.save!
end

if User.find_by_email("[e-mail]").nil?
  user = User.new
  user.email = "[e-mail]"
  user.password = "bonjovi5"
  user.password_confirmation = "bonjovi5"
  user.role = Role.find_by_name("standard")
  user.save!
end

When I run rake db:seed –trace , I get the following stack trace:

** Invoke db:seed (first_time)
** Invoke db:abort_if_pending_migrations (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:abort_if_pending_migrations
** Execute db:seed
rake aborted!
wrong number of arguments (3 for 2)

THis used to work, can anyone make any sense of what is going on? My gemfile looks like this:

source 'http://rubygems.org'
source 'http://gems.engineyard.com'

gem 'rails',               '~> 3.1.0.rc5'
gem 'sass-rails'
gem 'compass', git: 'https://github.com/chriseppstein/compass.git',branch: 'rails31'
gem 'fancy-buttons'
gem 'haml'
gem 'authlogic', :git => 'https://github.com/AndreasWurm/authlogic.git'#, :branch => 'rails3'
gem 'nokogiri'
gem 'bundler'
gem 'resque'              
gem 'resque-meta'        
gem 'jquery-rails'     
gem 'rake'#, '~> 0.8.7'          
gem 'eventmachine'
gem 'em-websocket'
gem 'json'
gem 'coffee-script'
gem 'uglifier'

platforms :jruby do
    gem 'activerecord-jdbc-adapter'
    gem 'activerecord-jdbcsqlite3-adapter'
    gem 'jruby-openssl'
    gem 'jdbc-mysql'
    gem 'jruby-rack'
    gem 'warbler'
    #gem 'glassfish', '1.0.3.dev'
end

group :test, :development do
  platforms :jruby do
    gem 'jdbc-sqlite3', :require => false
    gem 'fastercsv'
    gem 'ruby-debug'
  end

  platforms :ruby do
    gem 'sqlite3-ruby', :require => 'sqlite3'
  end

  gem 'mocha'
  gem 'factory_girl'
  gem 'fakeweb'
  gem 'shoulda', :require => 'shoulda'
end

Any help greatly appreciated.

This is a problem with the current version of activerecord-jdbc (1.1.3 as we speak).

Add this to your gem file and you should be good to go :

gem "activerecord-jdbc-adapter", 
    :git => "https://github.com/nicksieger/activerecord-jdbc-adapter.git"

Don’t forget to switch back to the gem repo when activerecord-jdbc 1.1.4 is released.
