From 16dadb1223fcabc9d904456d4b64d6e82f9e1a76 Mon Sep 17 00:00:00 2001 From: Chris Arcand Date: Wed, 23 Mar 2016 08:39:26 -0400 Subject: Make 'migrate' clear the schema cache afterward Without clearing the caches afterward, removals done in migrations would not be reflected in a separate task in the same process. That is, given a table with a migration to remove a column, the schema cache would still reflect that a table has that in something such as the 'db:seed' task: `rake db:migrate db:seed` (A common thing to do in a script for a project ala `bin/setup`) vs `rake db:migrate && rake db:seed` (Two processes) The first would not reflect that the column was removed. The second would (cache reset). --- activerecord/lib/active_record/tasks/database_tasks.rb | 1 + activerecord/test/cases/tasks/database_tasks_test.rb | 15 +++++++++++++-- 2 files changed, 14 insertions(+), 2 deletions(-) (limited to 'activerecord') diff --git a/activerecord/lib/active_record/tasks/database_tasks.rb b/activerecord/lib/active_record/tasks/database_tasks.rb index 261a6a264f..8881986f1b 100644 --- a/activerecord/lib/active_record/tasks/database_tasks.rb +++ b/activerecord/lib/active_record/tasks/database_tasks.rb @@ -159,6 +159,7 @@ module ActiveRecord Migrator.migrate(migrations_paths, version) do |migration| scope.blank? || scope == migration.scope end + ActiveRecord::Base.clear_cache! ensure Migration.verbose = verbose_was end diff --git a/activerecord/test/cases/tasks/database_tasks_test.rb b/activerecord/test/cases/tasks/database_tasks_test.rb index 429aeca1d9..0aac5bad31 100644 --- a/activerecord/test/cases/tasks/database_tasks_test.rb +++ b/activerecord/test/cases/tasks/database_tasks_test.rb @@ -309,19 +309,30 @@ module ActiveRecord end class DatabaseTasksMigrateTest < ActiveRecord::TestCase + def setup + ActiveRecord::Tasks::DatabaseTasks.migrations_paths = 'custom/path' + end + + def teardown + ActiveRecord::Tasks::DatabaseTasks.migrations_paths = nil + end + def test_migrate_receives_correct_env_vars verbose, version = ENV['VERBOSE'], ENV['VERSION'] - ActiveRecord::Tasks::DatabaseTasks.migrations_paths = 'custom/path' ENV['VERBOSE'] = 'false' ENV['VERSION'] = '4' ActiveRecord::Migrator.expects(:migrate).with('custom/path', 4) ActiveRecord::Tasks::DatabaseTasks.migrate ensure - ActiveRecord::Tasks::DatabaseTasks.migrations_paths = nil ENV['VERBOSE'], ENV['VERSION'] = verbose, version end + + def test_migrate_clears_schema_cache_afterward + ActiveRecord::Base.expects(:clear_cache!) + ActiveRecord::Tasks::DatabaseTasks.migrate + end end class DatabaseTasksPurgeTest < ActiveRecord::TestCase -- cgit v1.2.3
