Introducing Python Data Contracts

With this package you can define your own data contracts strictly and define data validations and pre-processing steps which will insure data integrity and capable of serializing to-and-from JSON format.

Example Usage

from serializer import Interface
class IP(Interface):

    # Declaring data type validations
    ip_address = str
    host_name = str

class Record(Interface):
    user_name = str
    age = int
    ip = IP

    # Pre-processors to standardize data
    def __user_name__(value):
        return value.capitalize()

args = {
    'user_name': 'ximi', 
    'age': 21, 
    'ip': IP(ip_address='192.168.2.1', host_name='localhost')
    }
request = Record(**args)
print ("Serializing from Object to JSON: \n", request.serialize())
# Serializing from Object to JSON:  
# {'user_name': 'Ximi', 'age': 21, 'ip': {'ip_address':'192.168.2.1', 'host_name': 'localhost'}}
args = {
    'user_name': 'ximi', 
    'age': 21, 
    'ip': {
        'ip_address': '192.168.2.1',
        'host_name': 'localhost'
        }
    }
request = Record(**args)
print ("Serialise with Reverse type conversion: \n", request.serialize())
# Serialise with Reverse type conversion: 
# {'user_name': 'Ximi', 'age': 21, 'ip': {'ip_address': '192.168.2.1', 'host_name': 'localhost'}}
