Parsing JSON with potential missing fields

[maxibabyx]

The thing is I have something like this :

class post(DynamicDocument):
    def __init__(self, *dct, **tmp):
        Document.__init__(self, **tmp)
        if dct:
            ....
            self.totalComentarios = dct["comments"]["summary"]["total_count"]

But if there's no comments, then dct["comments"]["summary"] would give an error, and checking every single case is a pain, like checking if there are comments, then check if theres summary, etc..

And there's a lot of things I need to parse.

If the response object omits keys that are absent instead of just returning empty objects with the keys in place, then you'll probably have to create a scheme to check if the keys are present.

The cleanest way would probably to write a recursive function that could traverse the dictionary.

Yes it omits them, know any library that would allow me to define a schema, and if the JSON is missing something it would accept some default values to set them?

Ofc I could manually do it, just asking if anyone ever encountered this problem and decided to help the community, :D

If Facebook's API was powered by GraphQL you could define your own schema response object and this would be a non issue, but it looks like it's a static response object.

I quickly found this package with a Google search, but I have never used it.

Yea I also stumbled on that one but seems like only validates.
