Using django-polymorphic with django-import-export #342
Description
I'm trying to use polymorphic models with the Admin import-export support provided by django-import-export. I've not (yet) looked into how this project does it's work, but a quick test reveals that the saved .csv file does not contain the fields from the subclass models (the saved data DOES contain the polymorphic_ctype as one might hope).
Now, I realise that the saved format of the data is a slightly tricky problem, especially if you have multiple levels of inheritance because the flat (relational-like!) format of a .csv file does not lend itself to the variable nature of the fields/columns. Maybe something like JSON encoding of the child fields might be needed?
At any rate, it would be nice to have this integration.
