django tables 2 - delete column and delete_item for inherited tables - django

Question

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.
