.. autoapisummary::

   src.utils_flask_sqla_geo.utils.geojsonify



.. py:class:: JsonifiableGenerator(gen)


   Bases: :py:obj:`list`

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

   .. py:attribute:: __repr__

      

   .. py:method:: __iter__()

      Implement iter(self).


   .. py:method:: __bool__()



.. py:class:: GeneratorField(cls_or_instance: Field | type, **kwargs)


   Bases: :py:obj:`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.

   .. py:method:: _serialize(value, attr, obj, **kwargs)

      Serializes ``value`` to a basic Python datatype. Noop by default.
      Concrete :class:`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()

      :param value: The value to be serialized.
      :param str attr: The attribute or key on the object to be serialized.
      :param object obj: The object the value was pulled from.
      :param dict kwargs: Field-specific keyword arguments.
      :return: The serialized value
