When a page connected to linkit is dropped the page where linkit was used starts returning a 500 error

I suppose the reason is that the data is stored using raw IDs instead of foreign keys with on_delete=PROTECT

Jep, you're right - that's a problem!

I don't want to solve this on the DB layer because I think the value column should be as generic as possible. The current implementation also allows for custom XYTypeForms where we have multiple additional fields and the value of these fields are json encoded in the value field.

Was the 500 related to any custom code by you? Because if you call label or href on a PageType link it should just return false (because the result of the real_value db query is null)

Maybe we can check registered LinkTypes with a django delete signal? Give custom (and existing) LinkTypes an option to tap into signals?
