Module: DataMapper::Adapters::AbstractAdapter::Queries

Defined in:

lib/data_mapper/adapters/abstract_adapter.rb

Overview

You define your custom queries in a sub-module called Queries. If you don’t need to redefine any of the default functionality/syntax, you can just create constants that point to the standard queries:

SelectStatement = DataMapper::Queries::SelectStatement

It’s just as easy to turn that into a sub-class however:

class SelectStatement < DataMapper::Queries::SelectStatement
end

You sub-class and edit instead of overwrite because you want to make sure your changes only affect this database adapter and avoid introducing incompatibilities into other adapters.
