Class Method Detail
def self.condition(table : String, column : String, expression : School::Expression, bindings : School::Bindings, block : School::DomainTypes -> SupportedType | Nil) : ConditionPair | Nil
#
Returns a SQL condition and values given an expression. The
supplied function must return an appropriate supported type (or
nil
) given a rules domain type.
Macro Detail
Makes a pattern class given a model class.
Ktistec::Rule.make_pattern( PatternClass, ModelClass, associations: [child_of], properties: [id, name] )
In order to perform a match operation, pattern classes have to
transform literals and bound values into the types the SQLite
client library understands. This imposes constraints on types
that participating model properties may use. In the example
above, properties id
and name
must be one of the supported
types.
