Quickstart

Generate a CODA file from a factory:

>>> from pycoda.factories import CodaFileFactory
>>> coda_file = CodaFileFactory()
>>> print coda_file.dumps()

Check the values of the first record:

>>> coda_file.records[0].field_dict()
{'account_holder_reference': 61411200863,
 'addressee': u'Anthony Hicks',
 'application_code': u'05',
 'bank_identification_number': 888,
 'bic': u'GKCCBEBB',
 'creation_date': datetime.date(2002, 5, 29),
 'duplicate': False,
 'empty': None,
 'free': None,
 'identification': 0,
 'reference': u'TWlscjlKSU',
 'related_reference': None,
 'transaction_reference': None,
 'version_code': 2,
 'zeroes': None}

Update a named field of the first record:

>>> coda_file.records[0].addressee = u'John Doe'
>>> print coda_file.records[0].dumps()
0000029050288805        TWlscjlKSUJohn Doe                  GKCCBEBB   06141120086                                             2

Make a new CODA file object and load the records / fields from the previous object string representation:

>>> plain = coda_file.dumps()
>>> from pycoda.codafile import CodaFile
>>> new_coda = CodaFile()
>>> new_coda.loads(plain)
>>> print new_coda.dumps()
0000029050288805        TWlscjlKSUJohn Doe                  GKCCBEBB   06141120086                                             2

>>> new_coda.dumps() == coda_file.dumps()
True

Model

The following model hierarchy is employed:

• CODA file: can consist of multiple records of given type
• Record type: each of the record types hold different specified named fields of given type
• Field type: the fields hold the actual values. All the parsing / printing footwork is done at this level

For each of those levels, the objects can:

• loads: set value from string representation
• dumps: generate string representation from value
