Functions

class src.utils_flask_sqla_geo.utils.JsonifiableGenerator(gen)

Bases: list

Inherite from list, so compatible with JSONEncoder, but must be initialized with a generator. Implement __bool__ as used by JSONEncoder.

__repr__

__iter__()

Implement iter(self).

__bool__()

class src.utils_flask_sqla_geo.utils.GeneratorField(cls_or_instance: Field | type, **kwargs)

Bases: marshmallow.fields.List

As marshmallow List field, but if value is not a list (e.g. map or generator), return a JsonifiableGenerator instead of a list.

_serialize(value, attr, obj, **kwargs)

Serializes value to a basic Python datatype. Noop by default. Concrete Field classes should implement this method.

Example:

class TitleCase(Field):
    def _serialize(self, value, attr, obj, **kwargs):
        if not value:
            return ''
        return str(value).title()

Paramètres:

• value – The value to be serialized.

• attr (str) – The attribute or key on the object to be serialized.

• obj (object) – The object the value was pulled from.

• kwargs (dict) – Field-specific keyword arguments.
