I'm testing Central but have stucked in an problem: After load some configuration from a json file I got error when try to use json.dumps to save the config data values to another json file:

>>> import json
>>> from central.config.file import FileConfig
>>> config = FileConfig('/opt/daspanel/data/civmw76wg000001p2dwqxpvet/db/civmw76wg000001p2dwqxpvet.json')
>>> config.load()
>>> json.dumps(config._data)

How I can convert the contents of config._data in an python string using json.dumps ?

the content of the original json file is:

Hi,

Just to let you know, this library hasn't been finished yet and it is meant to be a read-only config library.

config._data is not a Python dict, it is a IgnoreCaseDict that inherits from Python MutableMapping.

Unfortunately json.dumps doesn't support MutableMapping, you would need to implement your own JSONEncoder to make it work or you would need to convert it to Python dict.
