The json spec claims you must use a collection type at the top level of |

72

and decode non collection types that do not exist inside a collection. |
|
73
|
|
|
The to_python method relies on the value being an instance of basestring |
|
74
|
|
|
to ensure that it is encoded. If a string is the sole value at the |
|
75
|
|
|
point the field is instanced, to_python attempts to decode the sting because |
|
76
|
|
|
it is derived from basestring but cannot be encodeded and throws the |

exception ValueError: No JSON object could be decoded. |
