Support for inlines in Django Admin?

[danmanix]

Haven't been able to dig through Admin to find out how to apply the same kind of patching to inline objects as is done in the included ModelAdmin subclass.

If anyone has any pointers would be happy to try further.

This is what I use in my project

class TabularInlineTypedModel(admin.TabularInline):
    """Mixin copied typedmodels.admin.TypedModelAdmin"""

    def get_fields(self, request, obj=None):
        fields = super().get_fields(request, obj)
        # we remove the type field from the admin of subclasses.
        if TypedModel not in self.model.__bases__:
            fields.remove(self.model._meta.get_field("type").name)
        return fields

    def save_model(self, request, obj, form, change):
        if getattr(obj, "_typedmodels_type", None) is None:
            # new instances don't have the type attribute
            obj._typedmodels_type = form.cleaned_data["type"]
        obj.save()


class StackedInlineTypedModel(admin.StackedInline):
    """Mixin copied typedmodels.admin.TypedModelAdmin"""

    def get_fields(self, request, obj=None):
        fields = super().get_fields(request, obj)
        # we remove the type field from the admin of subclasses.
        if TypedModel not in self.model.__bases__:
            fields.remove(self.model._meta.get_field("type").name)
        return fields

    def save_model(self, request, obj, form, change):
        if getattr(obj, "_typedmodels_type", None) is None:
            # new instances don't have the type attribute
            obj._typedmodels_type = form.cleaned_data["type"]
        obj.save()
