Inheriting Schema models

[JoakimSoderberg]

Hello,

Is it possible in the Schema classes to inherit the properties from another class somehow?

The use case I have is that I have a bunch of different lists. All the lists share some common properties for pagination, the only thing that is different is the schema reference for the items in that list.

So what I would like is to reuse all those properties.

class ListModel(Schema):
    type = "object"
    properties = {
        "count": {
            "description": "The total number of items in the list",
            "type": "int"
        },
        "limit": {
            "description": "The number of items to show per page",
            "type": "int"
        },
        "offset": {
            "description": "Number of items to offset the pagination",
            "type": "int"
        }
        # "items" goes here in the inherited
    }

And then have multiple specific schemas for the different types:

class SomeListModel(ListModel):
    # properties should now get "items": SomeModel.array() added to it

Hmmm I mean I tried doing something like this:

class SomeListModel(Schema):
    type = "object"
    properties = dict_with_base_stuff.copy().update({"items": SomeModel.array()})

But I guess all that happens after the serialization is done. Because the result is just null in the output.
