MappingField Issue #16

Closed romcab closed 6 years ago

romcab commented 6 years ago

I'm trying to learn this great python package. However, I'm currently receiving and error when converting the json file into object. I'm wondering whey the value of rabbit was mapped to RabbitInfo object instead of the "rabbit" field.

Error: localhost is not an instance of <class 'test_serializer.RabbitInfo'>

class SerializerTest(unittest.TestCase): def test_json_to_config(self): original_json = open(JSON_FILE).read().strip() json_dict = from_json(original_json) compose = to_model(Config, json_dict) compose.rabbit.host == "localhost"

    # rabbit = to_model(RabbitInfo, json_dict)
    # assert rabbit.host == "localhost"

@related.immutable() class RabbitInfo(object): host = related.StringField(required=True) user = related.StringField(required=True) password = related.StringField(required=True) vhost = related.StringField(required=True)

@related.immutable() class WebInfo(object): url = related.StringField(required=True) user = related.StringField(required=True) password = related.StringField(required=True) eauth = related.StringField(required=True)

@related.immutable() class Config(object): rabbit = related.MappingField(RabbitInfo, "rabbit") web = related.MappingField(WebInfo, "web")

config.json { "rabbit": { "host": "localhost", "user": "my_user", "password": "my_password", "vhost": "local" }, "web": { "url": "localhost", "user": "my_user", "password": "my_password", "eauth": "local" } }
