Field

Typed query-field expression builder.

Usage

Source

Field(path)

Comparisons create immutable FieldPredicate values; asc and desc create FieldOrdering values. Use query where calls for AND semantics instead of Python and/or.

__lt__()	Create less-than predicate.
__ne__()	Create inequality predicate.
asc()	Order ascending by this field.
contains()	Create substring containment predicate.
desc()	Order descending by this field.
ends_with()	Create suffix predicate.
in_()	Create membership predicate; strings are rejected as sequences.
