From 69700c9ee760c5880fc80af70a89b42bb791cf98 Mon Sep 17 00:00:00 2001 From: John Hawthorn Date: Mon, 29 Jul 2019 08:40:57 -0700 Subject: Move DatabaseAlreadyExists detection to DB adapter Previously it was the responsibility of the database tasks to translate the invalid statement from creating a duplicate database into an ActiveRecord::Tasks::DatabaseAlreadyExists error. It's actually easier for us to do this detection inside of the adapter, where we already do a case statement on the return code to translate the error. This commit introduces ActiveRecord::DatabaseAlreadyExists, a subclass of StatementInvalid, and updates both AbstractMysqlAdapter and PostgresqlAdapter to return this more specific exception in that case. Because this is a subclass of the old exception, StatementInvalid, it should be backwards compatible with any code expecting that from create_database. This works for both create_database and exectute("CREATE DATABASE") --- activerecord/test/cases/tasks/mysql_rake_test.rb | 6 ++---- activerecord/test/cases/tasks/postgresql_rake_test.rb | 2 +- 2 files changed, 3 insertions(+), 5 deletions(-) (limited to 'activerecord/test') diff --git a/activerecord/test/cases/tasks/mysql_rake_test.rb b/activerecord/test/cases/tasks/mysql_rake_test.rb index ac3c5bc26e..4b039395e8 100644 --- a/activerecord/test/cases/tasks/mysql_rake_test.rb +++ b/activerecord/test/cases/tasks/mysql_rake_test.rb @@ -93,11 +93,9 @@ if current_adapter?(:Mysql2Adapter) with_stubbed_connection_establish_connection do ActiveRecord::Base.connection.stub( :create_database, - proc { raise ActiveRecord::StatementInvalid } + proc { raise ActiveRecord::DatabaseAlreadyExists } ) do - ActiveRecord::Base.connection.stub(:error_number, 1007) do - ActiveRecord::Tasks::DatabaseTasks.create @configuration - end + ActiveRecord::Tasks::DatabaseTasks.create @configuration assert_equal "Database 'my-app-db' already exists\n", $stderr.string end diff --git a/activerecord/test/cases/tasks/postgresql_rake_test.rb b/activerecord/test/cases/tasks/postgresql_rake_test.rb index f9df650687..d74ba0580d 100644 --- a/activerecord/test/cases/tasks/postgresql_rake_test.rb +++ b/activerecord/test/cases/tasks/postgresql_rake_test.rb @@ -129,7 +129,7 @@ if current_adapter?(:PostgreSQLAdapter) with_stubbed_connection_establish_connection do ActiveRecord::Base.connection.stub( :create_database, - proc { raise ActiveRecord::Tasks::DatabaseAlreadyExists } + proc { raise ActiveRecord::DatabaseAlreadyExists } ) do ActiveRecord::Tasks::DatabaseTasks.create @configuration -- cgit v1.2.3
