.action_on_strict_loading_violation

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

RDoc directive :singleton-method: action_on_strict_loading_violation

.after_all_transactions_commit(&block)

Registers a block to be called after all the current transactions have been committed.

If there is no currently open transaction, the block is called immediately.

If there are multiple nested transactions, the block is called after the outermost one has been committed,

If any of the currently open transactions is rolled back, the block is never called.

If multiple transactions are open across multiple databases, the block will be invoked if and once all of them have been committed. But note that nesting transactions across two distinct databases is a sharding anti-pattern that comes with a world of hurts.

# File 'activerecord/lib/active_record.rb', line 665

.async_query_executor

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.

.dump_schema_after_migration

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.

.error_on_ignored_order

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.

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 462

.lazily_load_schema_cache

Lazily load the schema cache. This option will load the schema cache when a connection is established rather than on boot.

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 198


RDoc directive :singleton-method: lazily_load_schema_cache

.message_verifiers

::ActiveSupport::MessageVerifiers instance for Active Record. If you are using ::Rails, this will be set to Rails.application.message_verifiers.

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 635


RDoc directive :singleton-method: message_verifiers

.migration_strategy

Specify the global default strategy to use for executing migrations. Individual adapter classes can override this by setting their own migration_strategy.

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 483


RDoc directive :singleton-method: migration_strategy

.protocol_adapters

Provides a mapping between database protocols/DBMSs and the underlying database adapter to be used. This is used only by the DATABASE_URL environment variable.

Example

DATABASE_URL="mysql://myuser:mypass@localhost/somedatabase"

The above URL specifies that MySQL is the desired protocol/DBMS, and the application configuration can then decide which adapter to use. For this example the default mapping is from mysql to mysql2, but :trilogy is also supported.

<code>protocol_adapters</code>.mysql = "mysql2"

The protocols names are arbitrary, and external database adapters can be registered and set here.

# File 'activerecord/lib/active_record.rb', line 621

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 549


RDoc directive :singleton-method: raise_int_wider_than_64bit

.schema_format

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. This can be overridden per-database in the database configuration.

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 454

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 245


def self.schema_ignored_table?(table_name)
  schema_ignored_tables.any? { |ignored| ignored === table_name }
end

.schema_ignored_tables

A list of tables or regex's to match tables to ignore when dumping the schema cache and the schema file. For example if this is set to [/^\_/] tables named with an underscore are dumped to neither.

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 241


RDoc directive :singleton-method: schema_ignored_tables

.schema_versions_formatter

Specify the formatter used by schema dumper to format versions information.

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 489


RDoc directive :singleton-method: schema_versions_formatter

.shuffle_unordered_selects

Shuffles the rows of every SELECT Active Record generates that has no ORDER BY clause.

The order of such a query is not specified, and databases are free to return its rows in any order. Enabling this option makes that explicit, so code (and tests) that accidentally rely on the order a given database happens to return today fails loudly instead of breaking later.

It is meant to be enabled in the test or development environments only.

Rows are shuffled after the database has returned them, so queries built from raw SQL strings are left untouched (Active Record cannot tell whether they are ordered), and queries ending in LIMIT 1 are unaffected because the database has already picked the row.

# File 'activerecord/lib/active_record.rb', line 432

Application configurable boolean that instructs the YAML Coder to use an unsafe load if set to true.

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 541


RDoc directive :singleton-method: use_yaml_unsafe_load

.validate_migration_timestamps

Specify whether or not to validate migration timestamps. When set, an error will be raised if a timestamp is more than a day ahead of the timestamp associated with the current time. .timestamped_migrations must be set to true.

RDoc directive :singleton-method: verbose_query_logs

.verify_foreign_keys_for_fixtures

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.

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 531
