Does not support object hooks

[johann-petrak]

The methods do not support the "object_hook" keyword argument. There also does not seem some other way to achieve the same result.

This seriously limits its usefulness. Are there any plans to implement object_hooks?

@johann-petrak yup, ujson doesn't supports the object_hook keyword argument, but you can implement a __json__ callable in your object to be serialized, at you can see here. I know it's not as elegant as the object_hook method, but you can work around with that (at least). I hope this helps!

Thank you, I was not aware of that!
This is of limited usefulness because it seems to expect the complete JSON-String for an object which could be useful for strange flat fields in an object but kind of defies the purpose of ultrajson for complex nested objects.
However there is apparently also support for "toDict" which maybe could be used to recursively allow ultrajson to build the json for a dict-representation of any object.

It would maybe help more people to include this in the README?

@johann-petrak I'm glad I could help! And I was not aware of the toDict method 😅

I think I made myself aware of __json__ when I read ujson source code, so, yes, either using the wiki or documenting ujson for these small hacks would be awesome (since knowing C is not a requirement to use ujson). I just bumped into your issue here and had an answer, I don't have any plans on contributing to this project (at least, not yet). I don't even know if there's any documentation done for the project or on the way. Bummer ...

Unfortunately the only documentation is the README, and PRs are very welcome to update that, or indeed write some "proper" docs :)

@vltr Thanks for your help commenting this and the other issue!

[vltr]

@hugovk no problem, I'm glad I could help. Perhaps you want to tag this issue with "docs needed" and create a "docs" item on #352?

[hugovk]

✅ Labelled "documentation" and "help wanted". The #352 release has already been made :)

"help wanted" is a life saver sometimes 😎
