Lovelace not accessible about pygrocy HOT 10 CLOSED

same here, the only way to get lovelace loaded is to restart hassio while webpage is loading and not reload it before you have disabled grocy integration.

Do you guys have barcodes associated with your products?

I have the same problems and yes i do use barcodes with my products

from pygrocy.

yes, I have barcodes.

Hey! I finally got the time to look into this, but it seems that this cant be fixed in pygrocy. The issue is that python doesn't know how to serialize the ProductBarcode object, but AFAIK it isn't possible to make objects serializable in python without changing the call to json.dumps. This call is located in homeassistant so the only way to fix this would be to change the data provided to HA in the custom component. I'm not sure how to do this, but other components had similar problems in the past (https://github.com/home-assistant/core/pull/34540/files).

I'm closing this for now, as I think this has to be fixed in the custom component unfortunately (@isabellaalstrom).

Thanks, I will try to fix.

@SebRut The default JSON decoder works with custom objects, if they have str as a parent object, I do that here https://github.com/ludeeus/awesomeversion/blob/main/awesomeversion/awesomeversion.py#L21

Test to prove it: https://github.com/ludeeus/awesomeversion/blob/main/tests/test_awesomeversion.py#L53

@ludeeus thank you for the hint, that sounds like a way to fix this. But I'm not sure if I like this solution because it leads to pygrocy being altered to be specifically compatible with HA by implementing a workaround.

Not really, that would enable the serialization of theses objects without creating and passing in a custom encoder to the dumper.
Everyone that uses this lib and JSON would benefit

Another option that will be easier to implement is to implement a custom encoder in this lib, and use that for the toJson() in https://github.com/SebRut/pygrocy/blob/develop/pygrocy/base.py#L13
json.dumps(self.as_dict(), cls: GrocyJSONEncoder)
