Comment (by BeryCZ):
Hello Natalia, thanks for your response, but I think you either
misunderstood or I'm missing something that's not clear from your answer.
Based on the docs https://docs.djangoproject.com/en/5.1/topics/db/models
/#multi-table-inheritance I can override the primary key on `ArticlePage`
so instead of `page_ptr` I can have just `page`. So that's what I'm doing,
it works when I put it in `ArticlePage` model, but not when I put it the
`AbstractPageType`.
I've just asked on discord and klove said it should be ok to name the pk
`page`.
So I even tried to remove my custom pk field and checked
`ArticlePage.page` and `article_page_object.page` and both raise
AttributeError, so by default `page` is not there.
My use case is - I want to have the "parent" model `Page` from which I can
MTI "submodels" like Article, Category, Product, Reference, whatever. The
`Page` model will then be used for references in other models (galeries,
urls, tree-maps, ...).
So, am I missing something, or is this a bug? I'm not saying it's an easy-
to-fix bug :) but I honestly think it is a bug.
I'm not even sure where the lazy load of `to` relationship is, or why it
doesn't work in abstract models, otherwise I would try to fix it and PR.
Thank you,
Bery
