+## Example

+
+# TODO update the JSON string below
+json = "{}"
+# create an instance of ModelField from a JSON string
+model_field_instance = ModelField.from_json(json)
+# print the JSON string representation of the object
+print(ModelField.to_json())
+
+# convert the object into a dict
+model_field_dict = model_field_instance.to_dict()
+# create an instance of ModelField from a dict
+model_field_form_dict = model_field.from_dict(model_field_dict)
