#async_query_executor ⇒ Object

:singleton-method: 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.

  @database_cli
end

#db_warnings_action ⇒ Object (readonly)

:singleton-method: db_warnings_action The action to take when database query produces warning. Must be one of :ignore, :log, :raise, :report, or a custom proc. The default is :ignore.

# File 'lib/active_record.rb', line 233

end

#dump_schema_after_migration ⇒ Object

:singleton-method: 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.



409

411
 
# File 'lib/active_record.rb', line 409

def dump_schema_after_migration
  @dump_schema_after_migration
end

#dump_schemas ⇒ Object

:singleton-method: 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.



419

# File 'lib/active_record.rb', line 419

def dump_schemas
  @dump_schemas
end

#error_on_ignored_order ⇒ Object

:singleton-method: 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.

# File 'lib/active_record.rb', line 380

def error_on_ignored_order

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

def permanent_connection_checkout
  @permanent_connection_checkout
end

#protocol_adapters ⇒ Object

:singleton-method: 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.

Class Method Details

.after_all_transactions_commit(&block) ⇒ Object

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.
