.action_on_strict_loading_violation

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

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 369


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.

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 572

  open_transactions = all_open_transactions

        open_transactions << current_transaction
      end
    end
  end
  open_transactions
end

.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.

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 424


RDoc directive :singleton-method: dump_schema_after_migration

.dump_schemas

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.

[ GitHub ]

RDoc directive :singleton-method: error_on_ignored_order

.gem_version

Returns the currently loaded version of Active Record as a Gem::Version.

.lazily_load_schema_cache

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 190

.message_verifiers

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

RDoc directive :singleton-method: message_verifiers

.migration_strategy

Specify strategy to use for executing migrations.

[ GitHub ]

# File 'activerecord/lib/active_record.rb', line 409


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.

ActiveRecord.protocol_adapters.mysql = "mysql2"

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

# File 'activerecord/lib/active_record.rb', line 528

.queues

Specifies the names of the queues used by background jobs.

def self.schema_cache_ignored_table?(table_name)
  ActiveRecord.schema_cache_ignored_tables.any? do |ignored|
    ignored === table_name
  end
end

.schema_cache_ignored_tables

[ GitHub ]

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


RDoc directive :singleton-method: schema_cache_ignored_tables

.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.
