File attachments on models in apps

[jdueitt]

We are in the process of porting an application we use for management from a stand alone ASP application into a nautbot app. The last feature that we're struggling to figure out the best path forward on is attaching arbitrary to the instances of the model. Similar to how image attachments are handled, but for non-image files.

I see the extras.FileAttachment, but it doesn't seem to have views and forms wired up to support the attachment. Is this because this is not how that's expected to be handled? Or, is it a case of it just hasn't been built out yet due to not being needed?

So far the gist of the model would be:

class Environment(PrimaryModel):  
    name = models.CharField(max_length=100, unique=True)
    description = models.CharField(max_length=200, blank=True)   
    file_attachments = GenericRelation(to="extras.FileAttachment")

    class Meta:
        ordering = ["name"]

    def __str__(self):
        return self.name

The URLs would be defined as:

router = NautobotUIViewSetRouter()
router.register("environments", views.EnvironmentsUIViewSet)

urlpatterns = [
    path(
        "environments/<uuid:object_id>/files/add/",
        # views.FileAttachmentEditView.as_view(), -- This doesn't seem to exist, but is the pattern that would follow what's done for ImageAttachments
        name="environment_add_file",
        kwargs={"model": models.Environment},
    )
]

urlpatterns += router.urls

Any suggestions on how the core app team feels this should be handled. If this is just a case of needing to build out the views and forms, we'd be happy to tackle that with submit a PR.
