class ICount(Aggregate):
name = 'ICOUNT'
sql_function = 'COUNT'
sql_template = '%(function)s(LOWER(%(field)s))'
is_ordinal = True
def __init__(self, lookup, **extra):
self.lookup = lookup
self.extra = extra
def _default_alias(self):
return '%s__%s' % (self.lookup,
self.__class__.__name__.lower())
default_alias = property(_default_alias)
def add_to_query(self, query, alias, col, source, is_summary):
super(ICount, self).__init__(col, source, is_summary,
**self.extra)
query.aggregate_select[alias] = self
