## Quickstart

Generate a CODA file from a factory:
```python
>>> from pycoda.factories import CodaFileFactory
>>> coda_file = CodaFileFactory()
>>> print coda_file.dumps()
0000029050288805 TWlscjlKSUAnthony Hicks GKCCBEBB 06141120086 2
10000 0000000026785942011208 000
2121170000 0000000700448471091015000000000 15030900000 0
8000 0000000000000000160417 0
9 134803000000336605556000000724123462 2
```

Check the values of the first record:
```python
>>> 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:
```python
>>> 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:
```python
>>> 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
10000 0000000026785942011208 000
2121170000 0000000700448471091015000000000 15030900000 0
8000 0000000000000000160417 0
9 134803000000336605556000000724123462 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
