From 871f45347778856feedf4b99c599e8acabc87ab6 Mon Sep 17 00:00:00 2001 From: George Deglin Date: Sun, 20 Sep 2015 22:32:26 -0700 Subject: [PATCH] Fix a bug with returning_disabled when using the postgresql adapter The returning_disabled configuration option is required to make postgresql partitioning triggers work. This commit fixes a bug where an invalid query would be made in cases where returning_disabled was true and objects were created with no attributes defined. --- .../connection_adapters/postgresql_adapter.rb | 2 +- .../postgresql/postgresql_adapter_test.rb | 15 +++++++++++++++ 2 files changed, 16 insertions(+), 1 deletion(-) diff --git a/activerecord/lib/active_record/connection_adapters/postgresql_adapter.rb b/activerecord/lib/active_record/connection_adapters/postgresql_adapter.rb index 9de79a614c..25dfda9ef8 100644 --- a/activerecord/lib/active_record/connection_adapters/postgresql_adapter.rb +++ b/activerecord/lib/active_record/connection_adapters/postgresql_adapter.rb @@ -761,7 +761,7 @@ module ActiveRecord end def extract_table_ref_from_insert_sql(sql) # :nodoc: - sql[/into\s+([^\(]*).*values\s*\(/im] + sql[/into\s("[A-Za-z0-9_."\[\]\s]+"|[A-Za-z0-9_."\[\]]+)\s*/im] $1.strip if $1 end diff --git a/activerecord/test/cases/adapters/postgresql/postgresql_adapter_test.rb b/activerecord/test/cases/adapters/postgresql/postgresql_adapter_test.rb index 6e6850c4a9..8eb57f08d0 100644 --- a/activerecord/test/cases/adapters/postgresql/postgresql_adapter_test.rb +++ b/activerecord/test/cases/adapters/postgresql/postgresql_adapter_test.rb @@ -123,6 +123,21 @@ module ActiveRecord assert_equal expect.to_i, result.rows.first.first end + def test_exec_insert_default_values_with_returning_disabled_and_no_sequence_name_given + connection = connection_without_insert_returning + result = connection.exec_insert("insert into postgresql_partitioned_table_parent DEFAULT VALUES", nil, [], 'id') + expect = connection.query('select max(id) from postgresql_partitioned_table_parent').first.first + assert_equal expect.to_i, result.rows.first.first + end + + def test_exec_insert_default_values_quoted_schema_with_returning_disabled_and_no_sequence_name_given + connection = connection_without_insert_returning + result = connection.exec_insert('insert into "public"."postgresql_partitioned_table_parent" DEFAULT VALUES', nil, [], 'id') + expect = connection.query('select max(id) from postgresql_partitioned_table_parent').first.first + assert_equal expect.to_i, result.rows.first.first + end + + def test_sql_for_insert_with_returning_disabled connection = connection_without_insert_returning result = connection.sql_for_insert('sql', nil, nil, nil, 'binds')
