Module: Sequel::Plugins::PreparedStatementsAssociations

Defined in:

lib/sequel/plugins/prepared_statements_associations.rb

Overview

The prepared_statements_associations plugin modifies the regular association load method to use a cached prepared statement to load the associations. It will not work on all associations, but it should skip the use of prepared statements for associations where it will not work, assuming you load the plugin before defining the associations.

Usage:

# Make all model subclasses more safe when using prepared statements (called before loading subclasses)
Sequel::Model.plugin :prepared_statements_associations

# Make the Album class more safe when using prepared statements
Album.plugin :prepared_statements_associations
