Defaults to `true`. +The SQLite3Adapter adapter adds one additional configuration option: + +* `ActiveRecord::ConnectionAdapters::SQLite3Adapter.represent_boolean_as_integer` +indicates whether boolean values are stored in sqlite3 databases as 1 and 0 or +'t' and 'f'. Leaving `ActiveRecord::ConnectionAdapters::SQLite3Adapter.represent_boolean_as_integer` +set to false is deprecated. SQLite databases have used 't' and 'f' to serialize +boolean values and must have old data converted to 1 and 0 (its native boolean +serialization) before setting this flag to true. Conversion can be accomplished +by setting up a rake task which runs + + ```ruby + ExampleModel.where("boolean_column = 't'").update_all(boolean_column: 1) + ExampleModel.where("boolean_column = 't'").update_all(boolean_column: 0) + ``` + + for all models and all boolean columns, after which the flag must be set to true +by adding the following to your application.rb file: + + ```ruby + ActiveRecord::ConnectionAdapters::SQLite3Adapter.represent_boolean_as_integer = true + ``` + The schema dumper adds one additional configuration option: * `ActiveRecord::SchemaDumper.ignore_tables` accepts an array of tables that should _not_ be included in any generated schema file. This setting is ignored unless `config.active_record.schema_format == :ruby`. |
