Instance Attribute Details

#action_on_strict_loading_violationObject

:singleton-method: Set the application to log or raise when an association violates strict loading. Defaults to :raise.


277
278
279
# File 'lib/active_record.rb', line 277

def action_on_strict_loading_violation
  @action_on_strict_loading_violation
end

#application_record_classObject

Returns the value of attribute application_record_class.


270
271
272
# File 'lib/active_record.rb', line 270

def application_record_class
  @application_record_class
end

#async_query_executorObject

Sets the async_query_executor for an application. By default the thread pool executor set to nil which will not run queries in the background. Applications must configure a thread pool executor to use this feature. Options are:

* nil - Does not initialize a thread pool executor. Any async calls will be
run in the foreground.
* :global_thread_pool - Initializes a single +Concurrent::ThreadPoolExecutor+
that uses the +async_query_concurrency+ for the +max_threads+ value.
* :multi_thread_pool - Initializes a +Concurrent::ThreadPoolExecutor+ for each
database connection. The initializer values are defined in the configuration hash.

# File 'lib/active_record.rb', line 213

def async_query_executor
  @async_query_executor
end

#default_timezoneObject (readonly)

Returns the value of attribute default_timezone.


183
184
185
# File 'lib/active_record.rb', line 183

def default_timezone
  @default_timezone
end

#dump_schema_after_migrationObject

:singleton-method: Specify whether schema dump should happen at the end of the bin/rails db:migrate command. This is true by default, which is useful for the development environment. This should ideally be false in the production environment where dumping schema is rarely needed.


311
312
313
# File 'lib/active_record.rb', line 311

def dump_schema_after_migration
  @dump_schema_after_migration
end

#dump_schemasObject

:singleton-method: Specifies which database schemas to dump when calling db:schema:dump. If the value is :schema_search_path (the default), any schemas listed in schema_search_path are dumped. Use :all to dump all schemas regardless of schema_search_path, or a string of comma separated schemas for a custom list.


321
322
323
# File 'lib/active_record.rb', line 321

def dump_schemas
  @dump_schemas
end

#error_on_ignored_orderObject

:singleton-method: Specifies if an error should be raised if the query has an order being ignored when doing batch queries. Useful in applications where the scope being ignored is error-worthy, rather than a warning.


296
297
298
# File 'lib/active_record.rb', line 296

def error_on_ignored_order
  @error_on_ignored_order
end

#index_nested_attribute_errorsObject

Returns the value of attribute index_nested_attribute_errors.


240
241
242
# File 'lib/active_record.rb', line 240

def index_nested_attribute_errors
  @index_nested_attribute_errors
end

#lazily_load_schema_cacheObject

Lazily load the schema cache. This option will load the schema cache when a connection is established rather than on boot. If set, config.active_record.use_schema_cache_dump will be set to false.


171
172
173
# File 'lib/active_record.rb', line 171

def lazily_load_schema_cache
  @lazily_load_schema_cache
end

#legacy_connection_handlingObject

Returns the value of attribute legacy_connection_handling.


180
181
182
# File 'lib/active_record.rb', line 180

def legacy_connection_handling
  @legacy_connection_handling
end

#maintain_test_schemaObject

Returns the value of attribute maintain_test_schema.


258
259
260
# File 'lib/active_record.rb', line 258

def maintain_test_schema
  @maintain_test_schema

#query_transformersObject

Returns the value of attribute query_transformers.


340
341
342
# File 'lib/active_record.rb', line 340

def query_transformers
  @query_transformers
end

#queuesObject

:singleton-method:

Specifies the names of the queues used by background jobs.


255
256
257
# File 'lib/active_record.rb', line 255

def queues
  @queues
end

#reading_roleObject

Returns the value of attribute reading_role.


200
201
202
# File 'lib/active_record.rb', line 200

def reading_role
  @reading_role
end

#schema_cache_ignored_tablesObject

A list of tables or regex's to match tables to ignore when dumping the schema cache. For example if this is set to [/^_/] the schema cache will not dump tables named with an underscore.


177
178
179
# File 'lib/active_record.rb', line 177

def schema_cache_ignored_tables
  @schema_cache_ignored_tables
end

#schema_formatObject

:singleton-method: Specifies the format to use when dumping the database schema with Rails' Rakefile. If :sql, the schema is dumped as (potentially database- specific) SQL statements. If :ruby, the schema is dumped as an ActiveRecord::Schema file which can be loaded into any database that supports migrations. Use :ruby if you want to have different database adapters for, e.g., your development and test environments.


288
289
290
# File 'lib/active_record.rb', line 288

def schema_format
  @schema_format
end

#suppress_multiple_database_warningObject

:singleton-method: Show a warning when Rails couldn't parse your database.yml for multiple databases.


328
329
330
# File 'lib/active_record.rb', line 328

def suppress_multiple_database_warning
  @suppress_multiple_database_warning
end

#timestamped_migrationsObject

:singleton-method: Specify whether or not to use timestamps for migration versions


302
303
304
# File 'lib/active_record.rb', line 302

def timestamped_migrations
  @timestamped_migrations
end

#verbose_query_logsObject

:singleton-method:

Specifies if the methods calling database queries should be logged below their relevant queries. Defaults to false.


248
249
250
# File 'lib/active_record.rb', line 248

def verbose_query_logs
  @verbose_query_logs
end

#verify_foreign_keys_for_fixturesObject

:singleton-method: If true, Rails will verify all foreign keys in the database after loading fixtures. An error will be raised if there are any foreign key violations, indicating incorrectly written fixtures. Supported by PostgreSQL and SQLite.


337
338
339
# File 'lib/active_record.rb', line 337

def verify_foreign_keys_for_fixtures
  @verify_foreign_keys_for_fixtures
end

#warn_on_records_fetched_greater_thanObject

:singleton-method: Specify a threshold for the size of query result sets. If the number of records in the set exceeds the threshold, a warning is logged. This can be used to identify queries which load thousands of records and potentially cause memory bloat.


267
268
269
# File 'lib/active_record.rb', line 267

def warn_on_records_fetched_greater_than
  @warn_on_records_fetched_greater_than
