batch_size

integer value of max record count inserted by 1 query/transaction

batch_transaction

bool (false by default), if transaction is used when batch importing

and works when :validate is set to true
before_import

proc for before import action, hook called with importer object

after_import

proc for after import action, hook called with importer object

before_batch_import

proc for before each batch action, called with importer object

after_batch_import

proc for after each batch action, called with importer object

validate

true|false, means perform validations or not

on_duplicate_key_update

an Array or Hash, tells activerecord-import

to use MySQL’s ON DUPLICATE KEY UPDATE ability.

timestamps

true|false, tells activerecord-import to not add timestamps (if false)

even if record timestamps is disabled in ActiveRecord::Base
ignore

true|false, tells activerecord-import to use MySQL’s INSERT IGNORE ability

template

custom template rendering

template_object

object passing to view

resource_class

resource class name, override to import to another table (default config.resource_class)

resource_label

resource label value (default config.resource_label)

plural_resource_label

pluralized resource label value (default config.plural_resource_label)
