1. Hello! I faced problem with adapters. …

   Scenario:
   I run tests on couple environments:
   test, lite, etc.
   But I get purge only on my "test" database when I invoke tests with RAILS_ENV=lite because of
       task :purge => :environment do
         abcs = ActiveRecord::Base.configurations
         case abcs['test']['adapter']
   It is wrong behavior and it breaks tests with connection error if adapters for test and lite differs.
   
   Makes me very sad about that. I had to monkeypatch my Rake file like so:
   
   # Add your own tasks in files placed in lib/tasks ending in .rake,
   # for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.
   
   require File.expand_path('../config/application', __FILE__)
   require 'rake'
   
   EUAdvantage::Application.load_tasks
   
   if %w(lite moscow).include? Rails.env
   
     tasks = Rake.application.instance_variable_get '@tasks'
     tasks.delete 'db:test:load'
     tasks.delete 'db:test:purge'
   
     db_namespace = namespace :db do
       namespace :test do
         task :load => 'db:test:purge' do
           ActiveRecord::Base.establish_connection(ActiveRecord::Base.configurations[Rails.env])
           ActiveRecord::Schema.verbose = false
           db_namespace['schema:load'].invoke
         end
         task :purge => :environment do
           abcs = ActiveRecord::Base.configurations
           case abcs[Rails.env]['adapter']
             when /mysql/
               ActiveRecord::Base.establish_connection(:test)
               ActiveRecord::Base.connection.recreate_database(abcs['test']['database'], mysql_creation_options(abcs['test']))
             when /postgresql/
               ActiveRecord::Base.clear_active_connections!
               drop_database(abcs['test'])
               create_database(abcs['test'])
             when /sqlite/
               dbfile = abcs['test']['database'] || abcs['test']['dbfile']
               File.delete(dbfile) if File.exist?(dbfile)
             when 'sqlserver'
               test = abcs.deep_dup['test']
               test_database = test['database']
               test['database'] = 'master'
               ActiveRecord::Base.establish_connection(test)
               ActiveRecord::Base.connection.recreate_database!(test_database)
             when "oci", "oracle"
               ActiveRecord::Base.establish_connection(:test)
               ActiveRecord::Base.connection.structure_drop.split(";\n\n").each do |ddl|
                 ActiveRecord::Base.connection.execute(ddl)
               end
             when 'firebird'
               ActiveRecord::Base.establish_connection(:test)
               ActiveRecord::Base.connection.recreate_database!
             else
               raise "Task not supported by '#{abcs['test']['adapter']}'"
           end
         end
       end
     end
   
   end
   
   
   Hope to hear Your opinion! It works for me but it surely not expected behavior for RAILS_ENV=some_not_named_test_environment_for_tests rake test.
   Thanks,
