Instance Method Details

#query_set(set_name, options = {}, &block) ⇒ Object

Defines a query set with the given name. This has the effect of defining a method that calls every implicit or explicit scope added to that query set.

When a block is given, that block is evaluated in the context of either a newly-created query set or (in the case of inherited classes) the pre-existing set of that name. See QueryableWith::QuerySet#queryable_with and QueryableWith::QuerySet#add_scope for more details.

When parent is given as an option, the new query set will inherit all of the scopes from the named parent.
