django tables 2 - delete column and delete_item for inherited tables

I want to have one abstract function for all my tablelists (one for each model) and (one delete_item) function in view.

I don't know how to make the delete (column in this table) and pass the model to the delete_item function in the view

Tables.py


    ############ Abstract Table
    class abs_Table(tables.Table):

    SN = tables.Column(empty_values=(), orderable=False)
    delete = tables.LinkColumn('delete_item', args=[A('pk'), ?????Model???],  attrs={
         'a': {'class': 'btn btn-small btn-dark'}
    # })


    def __init__(self, *args, **kwargs):
        super(abs_Table, self).__init__(*args, **kwargs)
        self.counter = itertools.count(1)


    def render_SN(self, record):

        pg = getattr(self, 'paginator', None)
        if pg:
            v = next(self.counter)
            return v + self.paginator.per_page * (self.page.number-1)
        else:
            return next(self.counter)


    class Meta:
        model = None
        fields = [ 'SN', 'id',  'delete', ]

        attrs = {"class": "table-striped table-bordered", 'width': '100%'}
        empty_text = "There are no Records matching the search criteria..."

Then for model Table

Tables.py


    class ModelTable(abs_Table):


    class Meta(abs_Table.Meta):
        model = modelname
        fields = abs_Table.Meta.fields+[selected_model_fields]

Views.py



      def delete_item(request, pk, delmodel):
        obj = get_object_or_404(delmodel, id=pk)


        if request.method == "POST":

                    obj.delete()

            return redirect("../")
        else:
            pass


        context = {
            'object': obj
        }

        return render(request, '/delete_confirmation.html', context)

For the Views part. It works for me after passing the model as string and then using apps.get_model to change it into a model.

views.py`

from django.apps import apps
def delete_item(request, pk, delmodel):

    DeleteModel = apps.get_model("Myapp", delmodel)
    obj = get_object_or_404(DeleteModel, id=pk)
    if request.method == "POST":
        obj.delete()
        return redirect("../")
    else:
        pass

    context = {
        'object': obj
    }

    return render(request, '/delete_confirmation.html', context)

Still the confirmation is not handled correctly and the delete column in tables need to be improved.
