Object of type Data is not JSON serializable #2

Closed bitnom closed 3 years ago

bitnom commented 3 years ago

I have a rather complex codebase in which I was previously dumping the dict form of my data to a JSON file. I refactored the entire code to use mo-dots only to finally encounter an error dumping to JSON:

TypeError: Object of type Data is not JSON serializable

Is it possible to stringify Data objects?

klahnakoski commented 3 years ago

json.dumps(team, default=lambda o: from_data(o)) may work. Give me some time to add some serialization tests; this short code does not handle FlatList (also found in this module).

I agree it is important that Data be able to serialize to JSON easily using the standard library. I use mo-json to perform the JSON serialization; I do not expect you to need that to do this.

.... confirmed: It can be done like so: 

json.dumps(team, default=from_data)

@TensorTom reopen if there are other combinations that cause problems.
