json-mapper 0.1.15

# About json-mapper

Package for map and parse JSON text to python dict.

For example, to bring to readable form of responses from the Rest API.

# Usage example

Suppose we have such a terrible JSON dump:

```python
{
"ApiResponse": {
"ApiResponseWrapper": {
"HotelsResponse": [
{
"Country": "Russia",
"HotelId": "1234",
"HotelName": "Space Hotel",
"Photos": [
{
"BigUrl": "http://www.image.url.com",
"ThumbnailUrl": "http://www.image.url.com"
},
... other photos ...
],
"RoomsResponse": [
{
"BedsCount": "1",
"RoomId": "12312"
},
... other rooms ...
]
},
... other hotels ...
],
"ResponseTimestamp": "2342423423423423",
"SessionId": "0ABAA840-F6EC-6913-A1C2-7341899060B6"
},
"SomeProperty": "SomeData"
}
}
```

Example to map the his pretty:

```python
import json
from json_mapper.mapper import map_json

json_data = json.loads(open('dump.json').read())

mapping_config = {
'ApiResponse.ApiResponseWrapper': {
'ResponseTimestamp': 'last_update',

'{loop=>hotels} HotelsResponse': {
'HotelId': 'id',
'Country': 'country',

'{loop=>photos} Photos': 'BigUrl',

'{loop=>rooms} RoomsResponse': {
'RoomId': 'id',
'BedsCount': 'beds'
}
}
}
}

result = map_json(mapping_config, json_data)

>>> pprint(result)
{'hotels': [{'country': u'Russia',
'id': u'1234',
'photos': [u'http://www.image.url.com',
u'http://www.image.url.com'],
'rooms': [{'beds': u'1', 'id': u'12312'},
{'beds': u'1', 'id': u'12312'}]},
{'country': u'Russia',
'id': u'1234',
'photos': [u'http://www.image.url.com',
u'http://www.image.url.com'],
'rooms': [{'beds': u'1', 'id': u'12312'},
{'beds': u'1', 'id': u'12312'}]}],
'last_update': u'2342423423423423'}
```
